I thought it may be that the LFE channel was out on my receiver, but after trying the sub on another receiver, I see that the sub is the problem.
Hooked up, it just gets a very faint bass signal. When I turn it up on the sub and the receiver I get a little more sound and a "pop" of bass on occasion.
Any ideas?
I shot an email to hsu tech support hoping they can help.
