Summary of the SVS SB16 Ultra (in room -3 dB floor of 15.5 Hz). The SVS SB16 Ultra is a GREAT answer to this question: Can I get world class bass in a subwoofer that is basically a 20 inch cube? On music, the Ultra 16 was very close to matching the agility of the EP800, with just a hint of bloat (under blind testing) that was not present in the EP800. The bass line from the David Sanborn disc was more on a par with the V3601 - both very good, just not best in class. It handles the Steely Dan material with ease, and is a subwoofer that usually disappears both physically and in the music performance. On movies, it hits the deep bass scenes with a little more authority than does the EP800, and while it IS possible to get it to audibly distort, it will only do so at SPL levels that the EP800 won't quite hit. Chalk that up to a little bit less aggressive use of the DSP. The Pods emerge scene form WOTW is surprisingly potent for a single, 16 inch driver - while not does not move the floor with the same ease as do the dual 18's from the PSA, it still makes for great cinema. Sam's arrival in the grid does cause audible overload with the SVS, but that's a small price to pay, considering the compact size and low entry price ($2000 delivered). Special merit for the smart phone App ... We are watching "DareDevil" on Netflix, and the bass is a bit overblown for the entire series. Being able to tamp it down from the listening position is a real plus. Overall ... the SB-16 Ultra gets and A- for both music and movies.
