Paradigm electronics has updated one of their most popular subwoofers. The new Servo-15 v.2 Subwoofer plays louder and deeper than its predecessor, the original Servo-15. With three times the RMS power output of the Servo-15, the Servo-15 v.2 is able to produce 121 db without distortion and is accurate to 10 Hz according to Paradigm.

The Servo-15 v.2 features Paradigm’s proprietary 15” high-excursion bass driver which has more than 2 inches of peak-to-peak cone travel that promotes deep bass response. The next-generation mineral-filled copolymer polypropylene cone, with RCR Resonance Control Ribs, is engineered for high power and low levels of distortion. The rigid, lightweight design of the three-inch, eight layer bifilar aluminum voice coils promote greater stability and support during extended cone travel according to Paradigm.

The Servo-15 v.2’s dual spiders and oversize long-travel suspensions encourage extended cone excursion while maintaining control over cone movement. The 29 lb. magnet structures generate a large magnetic force field while minimizing inductive distortion. With this in mind, the instrumentation-grade accelerometer is designed to withstand the driver’s extreme changes in motion. Other features on the Serrvo-15 v.2’ driver include a high-pressure, die-cast aluminum chassis, a proprietary AVS cooling and a large extruded aluminum ventilated center heatsink.

The subwoofer features an all new Ultra-Class D Switching Amplifier that provides 4500 watts RMS (FTC) power in optimized, high current, discrete output design with advanced patented servo controller. The novel adaptive PWP power processor minimizes distortion, while the 14 lb. low-noise high-power toroidal isolation transformer ensures prodigious output and ultra-quiet operation through a complete reduction in a stray magnetic energy says Paradigm. Opto-coupled inputs offer better isolation and lower noise.

Inputs include both RCA and balanced; control facilities include auto on/off, trigger on/off, subwoofer level control, continuously variable phase control from 0-80 degrees and bass contour, which allows for up to +6 dB boost at 60 Hz.

Paradigm also believes the amplifier’s precision components and dual-sided military spec (FR-4 rated) glass/epoxy circuit boards ensure performance and long term reliability. The advanced output stage is 10 times faster than conventional Class-D designs for superior efficiency.

Safety features on the amplifier include a proprietary voice coil temperature sensor, an amplifier temperature sensor and short circuit protection which reacts within 10 microseconds.

The Servo-15 v.2 subwoofer measures 20- 1/8 in. x 18- 1/8 in. x 21- 1/2 in., weighs 114 lbs. And is available in cherry, sycamore, rosenut and black ash. Suggested retail price is $2,200.
