The SVS subs are nice, but I would say they have a particular sonic signature that is popular with the "consumer electronics home theater crowd". It's sort of a larger-than-life type boomy of sound that a lot of consumers find attractive, but it is not necessarily accurate.
@auxinput What are you basing these assertions on? I’ve never read any review that says SVS subs sound like this. Further, I own an SB2000 and would not at all categorize them as “larger-than-life type boomy” sound.
