The Paradigm SUB 2 Reference Sibnature subwoofer may be the best-measuring, self-enclosed, powered home cinema subwoofer ever made!
As you might expect the amplifier is anything but conventional. This Class-D power plant can deliver a maximum continuous RMS power output of (gulp!) 4,500 watts with 9,000 watts of dynamic peak power when connected to a 240-volt line; it will deliver 3000 watts RMS with a 120-volt line. Both voltage options are available with the SUB 2.

The SUB 2 structure measures 24.5 inches tall, 23.75-inches wide and 22-inches deep. Those heavy motors and stiff cabinet mean that the SUB 2 is no lightweight, weighing in at a 230 pounds. You need at least three people to safely set it up.
Within the first couple of seconds of that first depth charge explosion, I knew the SUB 2 was a game changer. The entire room shook and the leather in the theater chairs flapped like they were in a giant wind storm.
Next I put on the Sum of All Fears, a terrorist drama that has a rogue nuclear explosion and an awesome stealth bomber take off. With every low bass effect, these ultra-low frequency experiences were something new, hearing and feeling sounds that don’t normally come from speakers or woofers of any kind. Even the finest movie theaters do not go where the SUB 2 goes — with low frequency extension of 7Hz (DIN)!

Next came critical music listening. I typically shut off my subwoofers when listening to music because of the cohesiveness of my good full-range system. But I wanted to try different crossover setting to see how flattering (or not) the SUB 2’s low end extension would be for music. I started with 80 Hz and was distracted by the location (slightly left of center) of the bass and kick drum on "Pineapple Getaway" from Fourplay - Let’s Touch The Sky album. I kept moving the crossover down with this directional characteristic decreasing as the frequency decreased and the best result ended up at lowest setting which is 35 Hz. There the kick drum was perfectly centered with tremendous whack.
