In case you missed our review of SVS SB-16 Subwoofer, we were pretty excited about this massive, gloss black, low frequency machine. You can read the full review here. However, if the SB-16 series is just a little bit too big for your environment, or a touch too expensive for your holiday budget, their new 4000 series is the way to roll. We compared the SB-16 series to the ZO6 Corvette. Hey, there’s no shame in getting a Grand Sport.
