Polk Audio Cobra Speaker Cable - 2 pc X 20 ft (round) Heres what Dick Olsher of The Absolute Sound had to say on the history of these... The Japanese were apparently first to commercialize a Litz-wire speaker cable, possibly based on the work of Kaneda and Egawa. Imported by Polk Audio circa 1977, it became recognized as the first high-end cable design and was commonly referred to as “Cobra cable” due to its distinctive appearance. It was constructed of two bundles of Litz wire (colored green and copper), one for each cable polarity, which were intimately woven together around a plastic core. Such a geometry drastically minimized cable inductance since the induced magnetic fields around the negative and positive conductors were in the same direction but in opposite polarity and largely canceled each other out. The resultant inductance was only 0.026µH/ft.—an order of magnitude lower than that of 18-gauge zip cord. The downside was a massive increase in cable capacitance to 500pF/ft. or almost 20 times that of 18-gauge zip cord. That didn’t sit well with marginally stable solid-state amps, which simply blew up when smitten by the Cobra’s capacitive venom.?

Please read the entire description before using Buy It Now to purchase these items. For sale here is a pair of vintage Polk Audio Cobra Cable braided speaker wires. These were manufactured in Japan. They are each 25 feet long (approximately 24-6 + the length of the terminations). They are in very good condition, with just one of the terminations missing (see the attached pictures). That particular end should be easy to re-terminate, because it is on the bare copper side (adding a termination to the enameled side would be more difficult, since the enamel would need to be removed from the individual strands to make the connection). These are the FLAT version of this legendary speaker cable. They are approximately 9/16 wide (13 mm) and 3/32 thick (2.33 mm). Each 25 spool weighs approximately 14 ounces (400 grams). This braided design results in a cable with extremely low inductance, supposedly making it one of the fastest ever made, with an extended high frequency response. This design also means that the cable has very high capacitance, which is what has made it somewhat controversial. Tube-based amplifiers are said to love this cable. The high capacitance is reported, though, to have caused some older, solid-state amplifiers to oscillate, resulting in damage to the amp. This shouldnt be a problem with most newer solid-state amplifiers, but I WILL NOT BE RESPONSIBLE FOR ANY AMPLIFIER DAMAGE that results from using these cables with amplifiers that are not compatible with them.

LEGENDÄRE POLK COBRA SPEAKER CABLE NEU !!! NOS !!! SEHR SELTEN !!! Das Kabel absolut NEU !!! UNBENUTZT !!! Das Kabel auf der Obrfläche hat noch Schutzfilm !!! ich biete hier meine nie genutzten Polk Audio Kabel zum Verkauf an. Es handelt sich um die mittlerweile sehr sehr seltene runde 10m Version.Es handelt sich hierbei um das beste jemals hergestellte Lautsprecherkabel, klanglich über alles erhaben, selbst bei einer Strecke von fast ganzen 10 Metern. Verbesserte Laufzeit, extrem hohe Auflösung und sehr gute Abschirmung vereinigen sich in diesem bis heute sehr gefragten Spitzenprodukt.Sie erwerben dieses einmalige Angebot in Deutschland und evtl. Weltweit !!! hier noch die Meinungen einiger Techniker aus dem Internet mit Quellenangabe: The Polk is extremely transparent, lucid, clean and extended in the highs. Accordingly, it is not a good match for those audiophiles looking for something euphonic to compliment digital or solid-state sound. It is the most revealing cable I have ever heard and it must be used in parallel or else it will sound noticeably lean on low- impedance, or even average impedance, speakers Art Salvatore - www.high-endaudio.com Peter Moncrieff of International Audio Review. Here is part of what he wrote in IAR Issue No #9: If only Polks resistance were lower, it would be a virtually perfect speaker cable...The beautifully flat error curve of Polk suggests a plan for creating the virtually perfect cable: run many Polks in parallel. They excell at soundstage and midrange detail. - MadMax, user of Polkaudio.com Bitte nur realistische Preisvorschläge !!!
