#140 PSB SubSeries BP8: $2,099.00 Estimated Amazon eBay
Same family: the PSB SubSeries BP7 (smaller subwoofer, estimated 3.3/5) and the PSB SubSeries BP12 (larger subwoofer, estimated 4.2/5).
Pros: A sealed subwoofer with two opposed 8” woven carbon fiber drivers and a 500W continuous nCore-based amplifier, rated 25 to 150Hz (±3dB) and 20Hz at -10dB from a 33cm cabinet.
