OOOOOOOOOOOO.....pretty! Paradigm's new Signature series of speakers have really taken them to the next level both sonically and in fit and finish. This entire line has some of the nicest wood finishes in the industry, from Bird's Eye maple to beautiful cherry. The Servo 2500 shown here has Paradigms new 1200 watt amplifier, which adds 6 dB more output then the Servo-15 model in the reference line up. Paradigm's subwoofer designers have been busy. There are three new models shown here. From left to right we have the 10" Seismic Sub, the 12" Seismic Sub, and the new PW-2100. All of these have Class-D (digital switching) amplifiers. The two Seismic Subs share the same 1200 watt amplifier as the Servo 2500 and while they look small, my back assures you the weigh a ton. They utilize a down-firing driver and two heavily weighted passive radiators mounted opposite one another. The PW-2100 is a downsized version of the PW-2200 with basically the same output thanks to the new 400 watt digital amp.
