THE WORLD'S MOST POWERFUL SUBWOOFER.
All ServoDrive loudspeakers incorporate a unique, patented operating principle involving
the substitution of high-speed rotary servo-motor and belt-drive system for the traditional
loudspeaker voice coil/magnet transducer system. The concept was created by renowned
engineer, Thomas Danley. In the years since their introduction, ServoDrive subwoofers
have heightened the awareness of the tremendous effect massive low frequencies have
in both fixed installations and touring sound applications. ServoDrive's BassTech
7s provide more sound pressure level capability than any other subwoofer on the market.
Features include: exceptionally low harmonic distortion, true high-fidelity performance,
virtually no output loss due to power compression, frequency response virtually flat
to below 28Hz, extraordinarily efficient - low power requirement for full SPL output.
The BassTech 7s display smooth frequency response (essentially flat from crossover
frequency down to 28Hz). Revolutionary motor-driven belt design increases linear
excursion and efficiency, handles large low-frequency peaks without damage or sonic
compromise.
The BassTech 7s have been on tour with the Rolling Stones, Michael Jackson, U2,
Garth Brooks, Phish, and Lyle Lovett. From Super Bowl half-time shows, to Disney
World, Universal Studios, the Mirage Volcano, Buccaneer Bay at Treasure Island, Crystal
Cathedral, and Blumenthal Theater - wherever crowds gather, these subwoofers are
guaranteed to bring a new level of excitement!
