Brand: NHT

#62 NHT B-12d: $699 Discontinued eBay

Pros: A compact sealed 12 inch subwoofer with a strong amp and a boundary control that adjusts it for its placement, now discontinued. It uses a 12 inch sealed driver with a 500W RMS BASH amplifier in a 356mm cube. Measured output reaches 114.4dB across the 40 to 80Hz bands and 99.9dB down to 20Hz. A Boundary Control lets you adjust the response for its placement without moving it.

Cons: It is rated 27 to 130Hz at -3dB, so it does not go as deep as larger ported subwoofers. At 15.3kg in a 356mm cube it is compact but still heavy for its size. It is discontinued, so it must be bought used. It is not the choice for a very large room.
