#140 BK Electronics Extreme: $5,995 Discontinued eBay
Pros: A big 15 inch subwoofer with a powerful amplifier and continuous phase control for flexible setup, now discontinued. It pairs a 15-inch driver with a 1000W RMS amplifier and measures 110.5dB average from 40 to 80Hz. Output holds 100.7dB at 20Hz and 92.8dB at 15Hz. Continuous 0 to 180 degree phase control helps blend it with the main speakers.
Cons: It weighs 91 kg, which takes two or more people to move and needs a strong floor. The price is very high for output that measures about 110.5dB average, which several far cheaper subwoofers match or beat. It is discontinued, so buying means finding one used.
Is the BK Electronics Extreme right for you?
