Two subwoofers in smallish HT room?


My home theater system is set up in a 16x11x8 ft room. I currently have one line-level HT subwoofer in the front-right corner. It's a very good subwoofer (Vandersteen V2W), but it needs to play pretty loud to produce good LFE. When it plays loud, it seems to localize.

I've been thinking about getting a 2nd sub and locating it near, but not in, the back left corner of the room in an attempt to smooth out bass response and give me the opportunity to turn down the volume on the front sub.

Does this make sense, or will it make in-room bass response worse? Is the room too small for two subs?

Two of the same subs for sure. I try to match wave launch of subs with that of the two front mains.Measure out from back edge of dust cap to front edge of each respective speaker and sub. The difference will be the amount of offset..Typical sub will be 1 to 3 inches in front of mains..Acoustical phase match of subs to mains is critical in this type of alignment though more easily heard and measured. Recommend direct coupling of speakers to floor for even smoother bass much lower spurious cabinet noise and better hand off to mains.Tom
Electrical phase reversal may actually be putting the sub in acoustical phase with the mains.You can also have a phase or timing issue with another sub plugged into a separate AC line other than that used for the main sub..Tom
db you now own both..Feel free to experiment, by doing so can only increase your experience and may be beneficial later on..I do feel your results will have you placing the hgs 10 in the lower level..Tom
