DESC: The U2 is a compact, two-cabinet subwoofer offering the same bass output as the U1, but made to serve different application and room requirements.Offering front firing drivers and an unusually compact enclosure size, the U2 modules can be installed in cabinets, on low shelves, or in corners with no compromise in bass output. And in rooms where bass performance is problematic-- too much bass caused by standing waves or too little as a result of cancellation -- the dual U2 enclosures can be placed in asymmetrical positions to help improve response.
