#4 HSU Research ULS-15 MK2: $999.00 HSU Research $999.00 eBay

Pros: A sealed 15 inch subwoofer with tight, accurate bass, a great value in large subs. Sealed design delivers tight, accurate bass with low bloat. 600W BASH amplifier. 30% less expensive and 20 lbs lighter than predecessor. Easy integration with Q and EQ controls. Great value in the 15” sub market.

Cons: No phone app or room correction, so setup is manual, and it ships in a plain vinyl finish where a similarly priced SVS offers gloss black. The foam surround is a minor durability worry compared with rubber, and larger sealed subs outperform it at the extremes.

Notes: Price includes shipping
