SVS SB-4000 Subwoofer Review

This is a review of the 13.5 inch 1400W RMS SVS SB-4000 sealed box subwoofer in the Premium Black Ash finish.

It replaces the previous generation SVS SB-13 Ultra, and is the little brother of the 16” SVS SB-16 Ultra.

Correction: the sub is only 1200W RMS, which is sadly on 4 times as powerful as my first sub!

I just got my SB 4000, and it is a nice sub. It keeps up with quick changes, yet it still slams hard when called for. It is very impressive.
