The Two Speakers In Full
SVS SB-5000 R-Evolution: $1,999.99 SVS eBay
Older model: the SVS SB-4000 (rated 4.2/5).
Pros: Sealed 15-inch high-excursion driver with a 2,000W RMS dual-monoblock amplifier and a 295MHz DSP. SVS rates it at 17-280Hz within 3dB. The SVS Subwoofer Control app adds DSP control and Auto EQ room calibration.
Cons: No independent measurements yet, so its output can’t be compared with ranked subwoofers. A sealed box trades some deep-bass output for tighter response compared with a ported design of the same size.
