Purchased brand new, my new system unfortunately doesn't allow for its integration. PC12–NSD – The original SVS subwoofer was a cylinder design, and this unique and elegant form factor has since become an iconic symbol of SVS performance heritage. The PC12–NSD is our most affordable powered cylinder, but after experiencing its performance, no one would dare call it 'entry level'. Every component reflects SVS performance pedigree, and the PC12–NSD obliterates over–priced and under–performing brick & mortar subwoofers, even at twice the price. Prepare to be pleasantly shocked at what the PC12–NSD will bring to your music and home theater system – bass so accurate, detailed, dynamic, and deep that after one listen your old 'subwoofer' will be kicked to the curb. Best In Class Performance Our Most Affordable Powered Cylinder Compact Footprint, Efficient Performance Features & details Our Sledge STA–400D amplifier sports technology and features simply not found anywhere else at this price point. Starting with a conservatively rated 400 watts of DSP–controlled power – a perfect match for the rugged NSD–12 driver. With only a 16.5" diameter footprint, the PC12–NSD will fit into almost any location, and no other subwoofer design offers more bass performance per square inch of floor space. Using vertical height to achieve a generous enclosure volume and a deep–tuned port, the result is excellent deep bass performance and outstanding mid–bass slam – all in a very manageable size.
