SVS PC-2000 Pro: $1,099.00 Amazon eBay
Older models: the SVS PC-2000 (rated 3.7/5) and the SVS PC12-NSD (rated 3.6/5).
Pros: Ported 12-inch driver in a cylinder cabinet that takes up less floor space than a box of similar output, driven by a 550W RMS (1,500W peak) Sledge amplifier. SVS rates it at 16-290Hz within 3dB in its standard mode. App control and the SoundPath isolation system are included.
Cons: No independent measurements yet, so its output can’t be compared with ranked subwoofers. At 34.3 inches tall it is more conspicuous than a box subwoofer, and ported output does not solve room modes on its own.
