Short answer: the HSU Research ULS-15 MK2. It ranks #4 of 212 subwoofers at $999 against the Power Sound Audio XV15’s #10 at $1,995, and its sealed cabinet delivers tight, accurate bass with low bloat. The PSA XV15 is a 15-inch ported downfirer with 500W that digs deep into the lowest frequencies, so it is the one to consider if output and extension matter more than pitch definition.
