HTiB sub question

[Rob J in WNY]

Don,

HAMP and Aramis are spot-on. Your bed is in a "cancellation zone" and that boils down to a locational problem. Rising the sub may help, but a complete locational change is just about your only option. Before you build a riser, see if you can place the sub higher on something to test the theory. A few inches will probably not really help you, but it's worth trying. Hate to say it, but moving your sub is likely going to be your only real solution.

I know that's an option that you cannot make right now, but could your bedroom be entirely rearranged so that you can put your bed where the bass is not nullified?

Yours is the perfect example as to the commonly mentioned notion that a sub can "go anywhere in a room because bass frequencies are non-directional." Whereas the latter part is true, room acoustics play a strong role in low-frequency propagation - no matter what the size of the sub.

Good luck to ya!
