Audyssey makes products to programatically equalize sound in home theater environments. I typically encounter these in receivers from various manufacturers.
I recently had the opportunity to work with the stand alone version for subwoofers. This system had one attached to a single subwoofer located in the front of the theater.
It appeared to do a reasonable job from 20 to 50 Hz, but was very poor from 50 to 100 Hz. This caused severe bass management problems with speakers that needed to have the speaker crossovers set above 50Hz. The phase of the subwoofer was also dramatically altered with this box in place making it difficult to phase the other speakers with the subwoofer.
In general I would avoid this unit. At a price of $799 I would allocate my funds to a second subwoofer, Rane PE-17 and/or a subwoofer with a manual PEQ. My experience with their receiver based products is better than this, but they are still vastly inferior to manually adjusting a subwoofer equalizer, receiver or preamp processor. Multiple subwoofers are a superior way to even out bass response in a room and reduce low frequency distortion. With a price of $799 you can purchase another subwoofer. The second subwoofer also does not need to be as powerful as the primary sub since its primary job will be to smooth the bass response from 30 to 120 hertz. A second subwoofer will also lower the overall distortion at these frequencies since each will need to output less sound to achieve the same sound pressure level. I find manual subwoofer equalization to be preferable to automatic calibration if you have the proper equipment or help in setting it up.
Is this a real A/V company? I entered www.AccuCal.com
and got a site about calibration......of pipets and a lot of industrial/technical jargon.
