While not a Spica product, the TC-50 / Kinergetics' SW-100 sub combination was prominently displayed in the Kinergetics brochure. The Kinergetics SW-100 subwoofer was offered in two configurations, the dual woofer SW-100 and single woofer SW-100.5. The SW-200 amplifier was a separate amplifier/crossover designed to drive the SW-100. The SW-100 sub/SW-200 amp combination was marketed as the BSC* Subwoofer System. Kinergetics also offered the "Music Mate" stands for mating the subs with a satellite system, prominently displayed with Spica TC-50's in the brochure.

The January 1990 Stereophile review of Kinergetics KCD-40 CD player references the TC-50 / BSC* subwoofer combination saying:

"..one thing I have noticed is that the small California company Kinergetics has invariably produced extremely musical sounds from CDs at CE Shows with a system put together around relatively modest-priced components, in particular a pair of Spica TC-50 speakers coupled with Kinergetics' BSC subwoofer system."


Kinergetics Research, closed its doors in August 2000 ending its 20 year run in audio. According to a September 2000 article in Stereophile, company president and owner Tony DiChiro attributed the company's shutdown to "a shrinking market for high-quality two-channel audio." which appears to have been the fate of many of the audio companies of this era.

*Bennett Sound Corporation (BSC) was apparently a division of Kinergetics, Inc. I found patents for BSC and Kinergetics listing the same engineer.
