The hand crafted Active Subwoofer cable is another weapon in the Synergistic Research arsenal. After the accolades and rave reviews received for Synergistic Research cables, from one generation to the next, we were urged to develop a subwoofer link. We developed specialized low frequency geometries, and of course installed Zero Capacitance Active Shielding technology to the inherent signal transfer aspect that low frequencies require. The results were nothing short of amazing.

We have always been aware of just how important phase coherency is in signal transfer. Now through our research we have discovered that lower frequencies are extremely sensitive to very small changes in phase coherency. For example: A 20 hertz low frequency wave requires at least 40 feet to propagate. If the phase is out, by just a little, it provides an unstable platform for the frequencies that are directly above. Higher frequencies have shorter wave lengths, and these are adversely affected by phase shift anomalies at the lower frequency range.

The new Active TESLA LE subwoofer cables feature the ability to change the voicing of your system via three different Active Shielding circuits, called “Enigma Bullets”. Each circuit features a different sonic characteristic:

• Silver Module = Open and airy
• Black Module = Warm and rich
• Grey Module = A hybrid of both the Black and Silver

The “Enigma Bullets” enables you to fine tune any component for a perfect system match.

TESLA LE Subwoofer 1 cables deliver the same benefits as our retired Alpha Sterling Active Subwoofer cables, but to a greater degree. Benefits start with deeper frequency extension, and not like turning up the volume on your powered subwoofer, but like upgrading to a much better subwoofer. The effect is not unlike spending many times as much on a much better subwoofer. As with all Synergistic Research Active Subwoofer cables, soundstage depth and width will be greatly enhanced, with layering and holographic presence that is startling at first listen. The TESLA LE Subwoofer 1 cable outperforms the Alpha Sterling in it’s application with higher performance powered subwoofers, to deliver enhanced detail from lower frequencies and the highest frequencies your system is capable of producing. Refinement of overall presentation will also be enhanced with smoother highs, more layered mid-range, and deeper, more extended bass frequencies, all with a more layered and holographic sound-stage.

“Enigma” Active Shielding Tuning Circuits.

Application: For systems seeking to optimize low frequency extension, with better integration, and an overall increase in sound-stage depth, width, and layering. Detail in the upper and mid-range frequencies will also be improved with more inner detail and extension when compared to Alpha Sterling Active Subwoofer cables.

Geometry: Dual Parallel (Active Conductors: Copper Matrix Type 1 )

Terminations: RCA and XLR

TESLA LE Subwoofer 2 cable is the perfect Active subwoofer cable for most music and home theater systems. It delivers all the performance found in TESLA LE Subwoofer 1 cables, but with a level of refinement and frequency extension that they cannot match. This cable delivers a huge expansive sound field; many times bigger than is possible without a TESLA LE Subwoofer 2 cable in your system. The increase in detail in the upper registers is possibly the most amazing aspect of this cable. At first listen, many users report hearing details from their favorite recordings for the very first time. Home theater buffs report imaging so improved they find themselves turning down their systems in the middle of a film to see if what they are listening to is coming from the score or from outside. To say that the TESLA LE Subwoofer 2 cable is a breakthrough is an understatement. This is a must audition product.

TESLA LE Subwoofer Reference cable is the choice for state-of-the-art audio and home theater systems. For systems whose performance potential warrants the high level of resolve these cables offer, no other subwoofer cable can compare.

Simply put, TESLA LE Subwoofer Reference is not for every system, as most systems are not capable of revealing the level of detail TESLA LE Subwoofer Reference can deliver. For those systems,  TESLA LE Subwoofer 2 will be the correct choice. But for a select few systems, TESLA LE Reference will deliver performance that a big a leap forward when compared to  TESLA LE Subwoofer 2 cable; as big a leap when comparing  TESLA LE Subwoofer 1 cable to the now retired Alpha Sterling Active Subwoofer cable. Of course, hearing is believing, so compare  TESLA LE Subwoofer 2 cables to TESLA LE Subwoofer Reference cables in your system before making your decision.
