Analysis Plus REL Subwoofer Cable - 4.0 Meter - SpeakOn connector - Bananas

Tight Clean Bass Enhances REL Subwoofers

The Analysis Plus REL Subwoofer Cable uses the Analysis Plus patented hollow oval design to give you the tight clean bass you expect to hear with REL powered subs.

This cable uses Swiss-made Neutrik SpeakOn connectors at the input to the REL 'sub bass system.' With over 100,000 RELs sold the world over, this connector has proven itself to be reliable, neutral, and mechanically ideal. Termination is with high quality bananas or spades.

Revolutionary Hollow Oval Conductor Design

Analysis Plus is uniquely qualified as an authority on speaker cable design. The Flushing, Michigan-based company earned its reputation testing and analyzing cables for leading cable manufacturers whose names you'd recognize in a flash. After examining the best, Analysis Plus decided it could do even better by developing its own proprietary hollow-oval conductor design.

Why the unique conductor geometry? Mark Markel and Qinwei Sun, the chief engineers at Analysis Plus at the time, determined that round cable used in conventional speaker cable designs has high levels of current bunching, skin effect phenomenon, and other frequency characteristics that degrade signal quality. Rectangular conductors were a little better, but these suffered high electric field values caused by sharp corners which can also cut into and injure the dielectric when the cable is flexed.

After many computer simulations, Analysis Plus found that a hollow oval cable was the best design due to its minimal change in resistance with frequency, plus other benefits. The company chose a flexible, braided conductor rather than the conventional solid conductor, which is susceptible to kinks and deformations with resulting signal degradation. A unique woven pattern places every wire statistically as close to the return current as every other wire for evenly distributed high-current density and superior sound.

Hand Constructed in Michigan

Analysis Plus cables are hand constructed in Michigan. Construction is quite labor intensive and can require up to one hour per cable. Analysis Plus relies on pure silver solder for all connections, which ensures not just high quality sound, but also as the cable ages and oxidation sets in, sonic degradation should be nil due to the conductive properties of pure silver.
