Revel B15 powered subwoofer. It has a 15" kevlar woofer and a 1000 watt internal amplifier. The sub retailed for $3000 and is made by the excellent US company Revel. Here are a few notes: Sound "Makes bass frequencies sound fast" -- "what it does is hit down low in a very tight and tuneful way," provides "hard-hitting and visceral" impact too; "illusion of the soundstage's scope increases substantially" with the B15 in use. Features Features a 15" "'ultra-rigid Kevlar pulp and alloy composite' woofer driven by a 1000W amplifier"; low- and high-pass functionality along with a built-in parametric equalizer for fixing bass trouble spots. Use "Revel supplies a CD of test tones" and "a special B15 setup disc" to aid in the fine-tuning process; "there is also Low Frequency Optimization (LFO) software that Revel has developed and which runs on Windows-based PCs"; "won’t take speaker-level connections." Value "At $2995, the Revel Performa B15 subwoofer is not cheap, but its value is apparent." Subwoofers are common in music systems today, but this certainly hasn't always been the case. Audiophiles of the time, though, wouldn’t have it. Although they certainly liked the idea of splitting their electronics into as many component chassis as they could, they wanted their stereo speakers only -- and preferably large stereo speakers. Enter the $2995 USD Revel Performa B15, the most versatile subwoofer I’ve come across. The B15 finally fulfills what’s been promised to hardcore audiophiles for so long: perfect integration along with staggeringly deep bass. Description Most subwoofers are rather simple and in need of only a paragraph or two to describe their features. Not the B15. There is a lot to this subwoofer. At the heart of the B15 is a 15" "ultra-rigid Kevlar pulp and alloy composite" woofer driven by a 1000W amplifier (reportedly capable of 1400W peaks). Revel says the B15 can produce 30Hz at 126dB in a "standard listening room." The driver has a 3" voice coil and a magnet that weighs more than eight pounds. All of this adds up to a subwoofer that can move serious amounts of air, extending a sub/sat speaker system to the point of being considered full range. do NOT contact me with unsolicited servic
