The Cardas Speaker Placement Guide. Setting up speakers in a golden ratio, golden cuboid, golden trapagon room, etc.. Speaker placement calculators. Speaker Placement Rectangular Room The Cardas Speaker Placement Guide Setting Up Speakers in a Rectangular Room Very precise speaker placement can open up a whole new dimension in listening, so I will outline the system that is becoming the standard of the industry. This standardized listening room is a Golden Cuboid and is the model for the math used in this system. This method will work with any box speaker, in any reasonably sized rectangular room. You may find that you have already positioned your speakers this way by ear. Active nodes are the main concern when placing speakers in a rectangular room. A node, or the frequency where speakers and parallel walls interact, is proportional to the speaker to the wall distance. The three most importance nodes, in order of importance, are proportional to the distance between the speaker and: 1. The side wall nearest the speaker 2. The rear wall 3. The side wall across from the speaker A secondary factor is the speaker-to-speaker time constant. When you use this Golden Ratio method to set your room up, the speakers are placed so the three nodes progress or differ from one another in Golden Ratio. This eliminates any unison or near unison resonance in the nodes. Panel or dipole speakers such as Apogees and Magnepans cancel their side waves, so a formula of .618 x the ceiling height can be used for determining placement from the rear wall. Most box speakers radiate low frequencies in all directions thus a formula that places the speaker to rear wall distance at 1.618 the side wall distance should be used. Speaker placement, simply stated: The distance from the center of the woofer face to the side walls is: Room Width times .276 (RW x .276) The distance from the center of the woofer face to the wall behind the speaker is: Room Width times .447 (RW x .447) This is all you need to know to place speakers in a symmetrical, rectangular room! The Near Field Listening Position In the near field position the speakers and the listener’s head are the points of an equilateral triangle. Near field listening gives the perfect stereo field. It is frequently used in the recording studio to position the microphones and the voice in the mix. The near field listening position is determined by the "center to center" distance of the speakers and the distance to the listener’s head. It does not refer to the room in any way. The importance of symmetrical speaker placement in a small room cannot be over emphasized. Once the speakers are set as close to perfect as possible, you must angle them slightly toward the listening position. This can be done by ear and usually a ¼ to ½ inch tweek will do. Box speakers generally require a bit more toe-in than planear speakers. You will be able to hear a center focused voice clarify when the sweet spot is hit. Near Field Golden Cuboid Listening Room Diagram The Golden Cuboid listening room is 10’ x 16’ x 26’ (Read 10.000 x 16.18033989... x 26.18033989... Its dimensions differ in a Golden Ratio or Fibonacci sequence (5-8-13-21-34...). The three major room nodes progress or differ in Golden Ratio and thus null rather than add or beat. Golden Cuboid Listening Room Relationships Expressed in Golden Ratio The Golden Ratio listening room is a relationship of potential nodes or energy storage units and can be expressed as a ratio or Golden Progression, using the speaker to speaker distance as 1. Golden Ratio Listening Room Relationships Expressed in Fibonacci Progression The Golden Ratio room set-up can be seen as a Fibonacci progression. Fibonacci Horizontal Listening Rooms If you are forced to place your speakers on the long side of a symmetrical, rectangular room, create a Golden rectangle in each rear corner. Your speakers can then be placed anywhere along a line extending from the outside rear corner through the inside front corner (Diagram F). Golden Rectangles, 1.618 from the side walls x 1 from the rear wall, create diagonal lines for speaker placement in a horizontal room. Horizontal Square Listening Rooms If you have the misfortune to have a square listening room, as in the previous setup (Diagram F), create Golden Rectangles in the rear corners of the room. Your speakers can then be placed along lines extending from the outside rear corners through the inside front corners (Diagram G). Square The Golden Trapagon The Golden Cuboid (Diagram H) is the best "rectangular" shape for a listening room. If, however, you have full architectural freedom, a Golden Trapagon (Diagram I) is by far the favored shape. A Golden Trapagon has a Golden rectangle for the front wall behind the speakers, and the room progresses to a larger (by Golden Ratio in area) Golden rectangle back wall behind the listener. For example, if the wall behind the speakers is 10 feet x 16 feet, the room would then be 26 feet long and the wall behind the listener would be 13 feet x 21 feet. Ideally, the rear portion of this room would vent into an attic space filled with fiberglass insulation. The trick to a Golden Trapagon shaped room is it eliminates the problem of parallel walls and the slap and sharp nodes associated with them. The "sound" of this room is a decaying hologram of the original, not a slap. This decay is exponential, or higher, at all frequencies. The relationship between the height and the width of the room, at any point, is Golden Ratio. The cross-section area at the rear of the room is 1.618 times the cross-section of the front. In the example above, the ceiling height would be 12.72 feet. The ratio of front height or width, to rear height or width, is 1.272 to 1. 1.272 is the square root of 1.618 or Golden Ratio. The progression of size at the ends of the room is a area relationship. The sound confronts the entire surface of the end walls at the same time, rather than progressively as with height and width. It is like tuning a guitar to a major chord, the side walls become the strings and the end walls are the bridge and tailpiece.

Cardas cables last forever. Which could be a problem, since your equipment might change. Fortunately, Cardas cables can be re-terminated with new connectors to suit your changing needs. And our lifetime warranty is there if you never have an issue. Obtain a return authorization to get a quote, and to send your cables in for service. Top Re-Termination, Repair, Warranty, & Authentication Service Click the button to fill out our Return Authorization Form, to initiate the process of having your cable re-terminated or repaired. Or read more about re-terminations and warranty service below. This form can be used for sending any Cardas product in for service, cable or otherwise. Return Authorization Form Our lifetime warranty We offer a lifetime warranty on our cables. In the unlikely event that your Cardas cables develops a functionality issue, please send it to us for repair. Just obtain a Return Authorization Number at this link , and follow the instructions. Before doing so, you're welcome to contact Cardas tech support for trouble-shooting guidance. Although the problem may be the cable, cable problems are exceedingly rare. It is not uncommon for somebody assume (or hope) that a cable is the source of a problem, send it to us for service, the cables tests perfectly, and they then realize that the actual problem is with one of their components. Perhaps wishful thinking is at play - it's a lot easier to send a cable in for service than it is to send a heavy amplifier or a delicate turntable. Our tech support advisor may be able to help you determine if the problem is truly with the cable. What is covered by the warranty? Bad or intermittent internal connections. Shorts. Loose connectors. General functionality & listenability issues. Nearly anything that can go wrong with a cable through no fault of the user. What is not? Wear and tear, such as scratched plating. Bent or broken banana plugs. Cosmetic issues. Animal damage. Vacuum cleaner damage. Re-terminations Our shop can re-terminate (ie, change the connectors on) your Cardas cables, should your needs change. • If you have a long pair of cables, we can cut & re-terminate it into two (or more) shorter pairs. • If you buy a new set of headphones, we can modify your Cardas headphone cable to work with them. • If you move from the US to Europe, we can put Shucko plugs on your Cardas power cables. • If you buy speakers with bi-wire binding posts, we can bi-wire your single-wire Cardas speaker cables. • If you switch from a balanced system to single-ended, we can change your Cardas interconnects from XLR to RCA. Or vice-versa. Nearly any Cardas cable can be modified in nearly any way. Note - we only service Cardas cables. If you have cables made by another manufacturer, they can perform this service for you. To begin the process of having your Cardas cables re-terminated, fill out the form at this link , and we'll contact you with a quote. Can't I repair or re-terminate my cables myself, or have a local shop do it? It's your cable, so yeah, do what you want. But we're glad to honor our warranty if your cable develops and issue. And if we repair or re-terminate your cable, your lifetime warranty remains intact. If Cardas cables are serviced elsewhere, the warranty becomes void. Keep in mind that we use Litz conductors. Even the most experienced technician or talented solder-ist (is that a word?) is unlikely to have much if any experience with this sort of wire. Most cables attempted to be serviced outside of our shop end up here anyway. So why not skip that frustrating and disappointing middle step? My cable has a problem, but I also want it re-terminated to different connectors. Can that be done under warranty? Our warranty polic y is pretty liberal, but it is limited to restoring your cable to its original state. In other words, if your headphone cable for Sennheiser HD800s develops a short, but you also want it re-terminated for use with Focal headphones, that is not a warranty repair. If your RCA interconnect has an issue, but you also want it switched to XLR, again, not a warranty situation. Authentication Service If you have cables that you would like us to inspect and authenticate, please fill out the form above, as you would for a re-termination or repair. Please be advised that cables deemed to be counterfeit will be indelibly marked and/or branded, and returned. If you purchased second hand cables and you doubt their authenticity, your best option is to return them for a refund from the seller.

Having started in 1987, there are a number of cables that we have discontinued in favor of newer, improved designs. Discontinued Cardas cables include Hexlink, Quadlink, Cross, Golden Cross, Neutral Reference, Golden Presence, Golden Reference, and Clear Light. Discontinued Cardas Products Hexlin k One of the earliest Cardas cable lines, Hexlink went through many variants in its lifespan. There was Hexlink, Hexlink Five Series, and Hexlink Golden 5C to name a few. In their time, Hexlink cables were our top-of-the-line performers. However many technical advancements over the years has allowed our entry & mid-level cables to outperform them. We'd suggest looking at Iridium or Parsec if you're considering Hexlink, but would rather get something newer. Also be aware that there are a lot of fake Hexlink cables out there. We've had good luck with eBay removing fraudulent Hexlink cables. Aliexpress, however, has nothing but fakes, and refuses to address the issue. Click here to read more about counterfeit Cardas cables . Quadlink Another classic dating to the early days of Cardas, the Quadlink cables were discontinued with the release of the Parsec cable line. Quadlink included interconnect, speaker, and power cables. Parsec took similar design geometries, and incorporated higher performing conductors. Cross Cross cables sat just below our then flagship Golden Cross. There were Cross interconnect, speaker, and power cables. Golden Cross One of the most sought after second-hand Cardas cables, Golden Cross remained at the top of our cable line for many years. Revered for its warmth, musicality and richness, Golden Cross cables command high prices on the used market. Golden Cross included an interconnect and speaker cable. A closely associated power cable, Golden Power, was also offered. Today, somebody seeking a cable with similar characteristics should consider Clear Reflection . Neutral Reference This was one of the first Cardas cables to break away from the "warm" end of the spectrum, in favor of - as the name implies - total neutrality. Neutral Reference included an interconnect, phono, and speaker cable. There was even a video cable. Remember those? In our current product line, both Clear Sky and Clear Cygnus occupy similar price points once held by Neutral Reference, with improved performance. Golden Presence Seated between Neutral Reference and Golden Reference, Golden Presence never caught on a best seller. An excellent combination of neutrality and musicality, most people either spent a little less and got Neutral Reference, or splurged on Golden Reference. Typical middle-child syndrome. But a great cable if you can find it on the second hand market. Golden Presence included an interconnect and speaker cable. As with Neutral Reference, modern day cables in a similar price & performance range include Clear Sky and Clear Cygnus . Golden Reference The cable that unseated Golden Cross as the king of Cardas cables. Combining the magical richness of Golden Cross with the neutrality of Neutral Reference, Golden Reference is still a great cable by modern standards, and remains at the heart of many spectacular stereo systems. Golden Reference included interconnect, speaker, power, and phono cables. To create Clear Reflection , we borrowed the geometry of Golden Reference, and incorporated our Matched Propagation conductors. Clear Light After developing Matched Propagation Conductors and creating Clear interconnect and speaker cables , George Cardas worked on a way of bringing similar performance to a lower price point. Coming up with a simplified conductor design, he made Clear Light interconnect and speaker cable. And eventually Clear Light headphone cable. Further developing and improving upon this conductor design lead to Clear Sky and Clear Cygnus . Unfortunately, Clear Light counterfeits have infiltrated the second-hand market. Unlike most counterfeits, these really look correct. Including the packaging and product literature. These fool us in pictures, and even in person... until we cut them open. What's inside is garbage wire. But on the outside, it all looks legit. So be very careful when considering second-hand Clear Light interconnect and speaker cables. Crosslink 6X and Crosslink 8X Both of these were variants of our Crosslink Speaker Cable , with 6 and 8 conductors, respectively. HD MI HDMI is a moving target, having already gone through several standards, with more surely on the horizon. As a small manufacturer, investing in the production of a product that might be obsolete in a year (or less) is dangerous territory. Our speciality and expertise is in audio. We're sticking with that. Cardas Clar ifier App We programmed the Clarifier App in-house, using cobbled together code and an HTML5 "wrapper" called Phonegap. It was an interesting learning experience. One of the main things we learned is that the people who charge $10,000+ to write mobile apps are not necessarily charging too much. We also learned that short of publishing a viral app, it would take about 100 years to start profiting from an app, when you take the cost (or time) of programming it into account. And in those 100 years, there are going to be OS updates and app-store requirements that force you to update your app, thereby putting you further behind in your efforts just to break even. Suffice to say that Apple & Android OS updates made Phonegap obsolete, which put us in a position of having no choice but to either start from scratch, or abandon the project.

In the early days of Cardas Audio, George Cardas realized that there was a lack of high quality connectors for his cables. So he designed and started making his own. We now offer many different audio connectors, plated with silver & rhodium, for cables, speakers, and electronic equipment. Connectors As with all Cardas products, our connectors are available through any Cardas dealer or distributor . This includes any physical store that carries our cables, or any online dealer . However we have dealers that specialize in parts & connectors who may be more knowledgeable about our parts offerings, and are more likely to have our parts in stock. Manufacturers who wish to purchase our parts in large quantities can buy directly from Cardas Audio. Read more about our OEM program at this link .

Cardas Quad Eutectic Solder, Rosin Flux Paste, and Cardas Contact Conditioner. They're supplies, because know, they run out. So you gotta re-supply. Solder & Supplies Roll Solder Bar Solder Flux Paste Contact Conditioner Where To Buy Quad Solder Cardas Quad Eutectic Solder Description: A proprietary blend of copper, silver, tin, and lead. Proprietary as in "please don't ask for the recipe because we're not telling, and we don't want it to get weird." No other solder flows as well, solidifies as uniformly, sounds as good or provides as durable and long lasting solder joints. There's a reason Quad Eutectic is considered the best in audio, and is widely used outside of our industry as well. Quad Eutectic Solder was developed in the early days of Cardas Audio when George Cardas realized that the available solders on the market - from hardware store grade to expensive silver-heavy solders - all had shortcomings that lead to degradation in sound quality & long-term reliability. He worked with an English metallurgist to arrive at the perfect blend of elements. The four elements in Qua d Eutectic Solder are in specific proportion to melt and solidify at a temperature lower than that of any of the component metals! Thus the resultant joint is contiguous from wire to connector rather than slurry - this provides a perfect and permanent connection that will never breakdown over time. Quad Eutectic Solder has a rosin core, and has a melting point of 350º F (177º C). Available on 1/4 pound and 1 pound spools. For soldering tips, check out our video series "Soldering With Jesus" , starring our head-terminator Jesus Ornelas. Please note: The label on Cardas Quad Eutectic Solder is changed on occasion. If you have a spool with a label that differs from what you see on this page, that does not mean your solder is counterfeit. As long as you buy from an authorized dealer , you're getting genuine Cardas Quad Eutectic Solder, regardless of the label. Part numbers: P41.6 for 1 pound spool P41.7 fo 1/4 pound spool Bar Solder Cardas Bar Solder Used in solder pots to tin Litz wire, we offer both leaded and lead-free bar solder.

Quadlink X speaker cable. Quadlink was based on our legendary Quadlink speaker cable, offering performance improvements. Quadlink X Interconnect Quadlink X Speaker The original Quadlink speaker cable launched in the mid 80's was one of Cardas Audio's most successful products. It stood the test of time. Quadlink X speaker was designed to offer better performance in all areas. Bigger bass, more detail, more richness. Quadlink X uses a similar geometry with a modified star-quad, larger air tubes, larger conductors, and advanced dielectrics. Quadlink X speaker is suitable for virtually any amp and speaker combination including those with difficult loads. In spite of exceeding our performance goals, Quadlink X became a victim of bad timing, as we had developed Cross speaker cable at the same time, and the two would have occupied similar price & performance points. So we shelved Quadlink X for the time being. Cross being long retired, we decided we'd release Quadlink X into the wild. The supply sold fast, with the only remaining Quadlink X being available through our dealer Music Direct .

Learn about our products, and contact us with any technical questions you might have. About Cardas About Cardas Audio A brief history of Cardas Audio is below. However this video, "American Made: Cardas Clear Beyond" , produced by Jana Dagdagan in 2021, tells the story of current-day Cardas Audio beautifully. A Brief History of Cardas Audio Cardas Audio is located in Bandon, a small town (population 3, 321) on the Southern Oregon Coast, about 1.5 hours north of the California border. We specialize in premium audio cables, consisting of multi-stranded Litz conductors, featuring our own ultra-pure copper. We also produce high quality connectors, chassis wire, bulk cable, and accessories for home & pro audio systems. Our company was founded in Ontario, California, in 1987, by George Cardas. George’s previous career was as a line engineer with the telephone company. He had a strong background in challenges of transmitting audio over cable. He was also an avid, and quite successful, semi-pro racing driver. He and his machinist, Mike Colver, came to realize that Golden Ratio proportions could be applied to various aspects of engine and exhaust design. And the results were often so successful that their designs would be banned in their racing league for giving them an unfair advantage. A music lover and HiFi enthusiast, George came to realize that cables were a limiting factor in his audio system. He began experimenting with cable design, applying what he knew from his career with the telephone company, and using Golden Ratio scaling of conductors to reduce resonance, and came up with some very effective designs. His cable consisted of multi-stranded Litz conductors. In a Litz conductor, every strand of wire has an enamel coating to eliminate cross talk, and to prevent oxidation of the copper. George's conductors featured Golden Ratio scaled strands, in which the smallest strands were at the center, with each layer of wire being a Golden Ratio step (1:1.618) larger than the layer beneath it. This stranding is a micro-resonance control technique, and George was awarded two US patents (4,980,517 & 4,628,151) for his cable & conductor designs. He also found the last copper producer in the US who could make ultra-pure, fine copper wire to his specifications. They were on the verge of closing their doors, but George made a deal with them - keep going, and I'll keep ordering copper. The copper they produced with George's method is the purest, highest quality copper wire available. His next challenge was getting a cable factory to take him seriously and produce his designs for him. Most of them dealt exclusively with military contracts, and were accustomed to making many thousands of feet of cable at a time. George just wanted a few hundred feet to see if it would sell. Through persistence, he finally persuaded a vendor in Southern California to produce his designs. He made cables for friends, and got enthusiastic positive feedback. But to make it a business, he had to get his cable into stores. He once again faced resistance. But he finally got his local stereo shop to give his cables a try. The owner was reluctant, but agreed to audition the cables. George came back a few days later, and the guy was blown away. He became George’s first dealer, and sales slowly but steadily grew. At first, George and some friends would terminate cables in the family garage, and George continued to work at the phone company. But soon, the cable business showed signs of becoming self sustaining. He and his wife, Darcy, decided it made sense for him to take early retirement, and focus on Cardas Audio. Before long, the Cardas “factory” moved out of the garage, and into a space in an industrial park. And business continued to grow, with new dealers in the US, and distributors in other countries, signing on to represent the cables. George and Darcy’s oldest daughter, Mary, ran the business side of the company, while George focused on product design. A few years later, in 1992, when the lease came up on the manufacturing space, George and Darcy thought it made sense to consider other options. They could renew the lease and stay put, or… maybe move somewhere else. They decided to drive up the west coast, eventually stopping in Bandon, Oregon. They fell in love with the small town, and decided to move the ocmpany north, bringing with them their staff. Expect Mary. She decided to stay in Southern California. So they brought their middle daughter, Colleen, to take over as manager. Over the years, both Bandon and Cardas grew. Once primary a cranberry farming town, a new golf resort just north of the city, Bandon Dunes, really put Bandon on the map. And George continued to work on new cable ideas. Whereas his early cables, such as Hexlink and Golden Cross, helped tame the edge of early digital recordings, he started to work on more revealing and sonically accurate cables such as Neutral Reference and Golden Reference. And these new cables sold really well. George continued to work on cable designs, most recently receiving US Patent US7674973B2 for what we call the Matched Propagation Conductor. This conductor matches the propagation rate of the signal in the conductor, which is essentially light speed, to that of the dielectric materials, which are generally 30% slower than the speed of light. This mismatch has plagued audio cables since the beginning of the telephone age, causing smeared, unintelligible audio over long distances. Telephone companies attempted to solve the issue using loading coils, developed by Mihajlo Pupin in the early 20th century. George’s solution is much more graceful - and effective - utilizing specific wire-winding pitches and carefully selected dielectric materials, eliminating the issue within the cable, and continuously throughout the cable. Our Matched Propagation Conductors are used in all of our cables within the Clear range, which includes Clear Sky, Clear Cygnus, Clear SE9 MP, Clear Reflection, Clear, and Clear Beyond. Today, Cardas Audio is managed by George & Darcy’s youngest daughter, Angela. George continues to be the head designer of Cardas products, and he and Darcy split their time between Bandon, and Chapala, Mexico. And our capable staff holds down the fort while they’re away

Neutral and accurate cables, allowing your high performance audio system to perform at it's best. Amazing spatial imaging and musicality. Anchor 1 Clear “I’ve been using Cardas since the early days of my audiophile journey. I’ve enjoyed the progression of improvements, starting with Hexlink, then Golden Cross, followed by Golden Reference.

Cardas Grade 1 Ultra Pure Copper is used in nearly all of our cables, and also by other cable & equipment manufacturers. In fact, there are laboratories in the US & Europe using our copper for its superior electrical and thermal conductive properties. Cardas Grade 2 Copper is a more affordable variant, but still of extremely high quality, and produced using similar methods. Grade 2 can be found in our own 101 Speaker and Crosslink cables. Grade 2 is also used throughout the audio industry. Cardas Silver is used in Clear Beyond Headphone Cable , and is very popular with other high-end cable and electronics manufacturers. Cardas Copper & Silver is sold by weight, rather than by the foot or meter. Large minimums & long lead times apply. Copper & Silver strand is not available through our dealers. If you're not sure if you should be considering Cardas Chassis Wire or bare copper or silver strand, the answer is Cardas Chassis Wire . If you're interesting in buying dozens or perhaps hundreds of pounds of copper or silver strand, contact Darla in our front office. Comparing Copper We electrically etched away the outer layer of several copper strands manufactured using differing methods, to demonstrate that the perfect grain structure of Cardas Grade 1 extends below the surface. How to buy: Cardas copper & silver strand is typically sold by the pound, and long lead times may apply. We have a limited variety of gauges in house, If we have the AWG you want in stock, you may purchase as little or as much as you wish. However if you need a gauge of copper or silver that we do not have in stock, the minimum production run is between 200 and 800 pounds, depending on the gauge.
