TONE Audio Reviews the PC-4000 Subwoofer
"Digs down deep. In a larger room, it was easy to achieve near concert hall levels, and we could not drive the PC-4000 to clipping or exceed the woofers excursion levels. Excellent upper bass response, with low coloration, making it easy to mate with a wide range of main speakers. If you need bass, and floor space is at a premium, the SVS PC-4000 is the way to go."
