SP4BW-BK02S
Engineered by noted high-end cable designer Jay Victor; the SP4BW is designed for use with high performance audio systems that will delight even the most discerning audiophile.
SP4BW has a unique internal Star-Quad design; two of the four conductors are 14AWG for low frequency loudspeaker driver terminals and two conductors are 16AWG for connection to the high frequency terminals making this a perfect cable for a bi-wire speaker environment. If a 2-Channel cable is desired combining conductors will result in a 12AWG speaker cable.
Star-Quad geometry consists of four conductors wound together in a "positive, negative, positive, negative" configuration. The result is the cancellation of opposing electromagnetic fields generated by each conductor pair. This design improves the system's performance by preventing EMI noise from entering and distorting the signal. For even more sound clarity the SP4BW is engineered with propriety cable winding geometry to reduce distortion. Each conductor is made with 6 bundles of stranded wire wound clock-wise then these bundles wind counter clock-wise around a larger solid center conductor that is insulated with a precision formulated PE dielectric. This design ensures low-loss, superior imaging and improved musical definition to deliver a wide-open sound stage.
Termination and testing of SP4BW is done at our facility 
in Orlando, Florida. As a result, this cable can be configured in any lengths as a standard 2 channel speaker cable with 2 connectors on each end or as a bi-wire cable with 2 connectors on the amplifier end and 4 connectors on the speaker end. When terminated as a bi-wire cable, the speaker ends are labeled as "Low Pass" (14AWG) and "High Pass" (16AWG). The cable can be terminated with various banana plugs or spade lugs and is available in zip lock bag packaging or Display packaging for retail stores in individual lengths (mono) of 4ft, 6ft, 8ft and 10ft.
Cosmetically, the PVC UL® CL2 jacket has a 13mm (½") O.D. and is covered with an elegant black and royal blue woven material that matches the color of Series 4 Audio cables. The SP4BW is available on 200ft spools. For in-field terminations, kits are available with enough rubber boots and heat shrink to make 10 cables. So not only does the SP4BW outperform most moderately priced speaker cables on the market but it out dresses them as well!
SP414UL-BK02S
Designed to be used in Atmos® or other multi-speaker surround systems as an upgrade to standard 14/2 bulk CI wire, SP414UL is constructed of two 14AWG HC-OFC conductors each engineered in a multi-gauge cable configuration housed in a black UL® CL2 PVC, siamese-type jacket. This conductor configuration improves the overall sonic performance of the cable by providing an easier path for low frequency signals improving bass response and sound clarity.
SP414UL is flexible and easy to terminate in the field. Standard bulk CI 14/2 is made of two 14AWG bare copper stranded conductors individually insulated and then covered in a tube jacket. When terminating the CI wire the outer jacket is cut and then the inner insulators need to be stripped creating more work and leaving the end result looking rough. The SP414UL is vastly simpler to use. Simply pull the 
positive conductor from its negative twin in the siamese cable and strip the ends. The result is professional and clean with less effort. So there you have it, the SP414UL simply sounds better and terminates faster with a fit and finish your customer's expect from a specialty installer.
SP144UL is available on 200ft spools or terminated with banana plugs or spade lugs. Also available in ziplock bag packaging or Display packaging in individual lengths (mono) of 4ft, 6ft, 8ft and 10ft.
