Brand: SVS
#119 SVS 20-39 PC-Plus: $1,399 Discontinued eBay
Pros: A 12 inch ported cylinder subwoofer that stands tall on a small footprint, now discontinued. It has a 525W RMS amplifier and measures 112.3dB average from 40 to 80Hz. Output stays at 102.7dB at 20Hz and 91.0dB at 15Hz, rated down to 16Hz. The down-firing cylinder is about 406mm across, so it takes little floor space.
Cons: It stands 1016mm tall and weighs 24.9 kg, so it is tall and needs space to clear the port. It is expensive for a 112.3dB average. Ported designs can add port noise at high output. It is discontinued, so you would need to find one used.
Notes: “Cylinder” shape
