The S1500 represents a new standard in compact subwoofer value. With new ICEpower® amplifiers, improved SE drivers, and updated cabinet design the new S1500 takes everything that made the XS15se an excellent value and improves upon it. The new S1500 offers deeper extension, increased output, and better overall sound quality. The satin black finish combined with the new form factor allows the S1500 to disappear into virtually any home decor. You simply cannot find a better value in the industry today.

AVS member RN2013 posted a detailed review of his experience with the new S1500. Click on the AVS logo below to read the full review.

"the great thing I found using the S1500 is that the improvements are apparent on virtually all recordings, not just the “demo your system audiophile recordings."

"the low end sound/support it provides is clean, deep, has a really good pitch and blends well with the mains"
