BIC produces BIG bass without busting your bank account. 100 watts of RMS power and a down firing speaker will give pleasant lows without the boomy sound, just a nice punch of extra low frequency bass that will fill a small to medium sized room. Nice complement to any surround system. Very compact and can be hidden very easily.

Can't think if any.

Low cost.

Hums.

This thing hums all the time. It works, but you can hear a hum if you sit within 5 feet of it. It's not my receiver since it occurs on two receivers that I have and other subs don't hum with those same receivers. I tried plugging it into the same outlet as the receiver and in different outlets. It always hums. When I try to move it, it hums really loud. I think Something is loose. I called BIC tech support and they wouldn't take it back. They gave me a suggestion for fixing it that included shielding with tin foil. Why am I fixing it? I still own it and use it, but I wish I'd bought something else.
