Description:
Infinity's BU-120 Powered Subwoofer is everything most people want in a subwoofer: high powered, flexible, simple to use, and earth shaking. Tuned well, it's hard to believe there's really a subwoofer in use; the bass seems to emanate naturally from the other speakers. A continuously variable crossover (50 to 150 Hz) and level control allow the BU-120 to blend with nearly any room and system. Achieving the perfect crossover point and volume level will depend entirely on your other speakers and your taste, so suit yourself--this subwoofer lets you. Positioning can be tricky, so if it doesn't sound perfect right off the bat, try moving it around some; a 180-degree phase-invert switch helps with distances of more than five feet. Infinity recommends placing the BU-120 away from walls, and we found our sweet spot--the point where the subwoofing low frequencies blended seamlessly with the rest of our system--in fairly short order. Setup, while simple, will depend on how you want to configure your system, but rest assured that the flexible BU-120 can accommodate receiver/preamplifiers with dedicated subwoofer/low-frequency outputs and those without. The flip side of this flexibility is that the BU-120 wants two inputs, a left and a right, even if you're feeding it a mono, low-frequency output (as in a Dolby Digital or DTS 5.1-channel system). In that event, the monaural signal must be split using an RCA "Y" cable (one female to two male, not supplied)--an inexpensive but inconvenient fix. For dynamic, made-to-order low-end presence at a reasonable price, the Infinity BU-120 is hard to beat. Pros:
- Ease of placement
- Flexible configuration
- Floor-shaking bass
Cons:
- Connecting cables not supplied
