    I have this hooked up to a sub output on a Sony tv. Decent sub for extra bass. I will be buying another one for a tv in the bedroom.

    We are using this sub in addition to another sub which we already have. The action movies are on another level now. The ability to change the phase on this sub was helpful. The original phase setting in our basement caused the bass to cancel out between our two subs. I switched the phase on this one and..... Boom! That is what I now feel during the movies!

    No regrets! Definitely glad I made this purchase. Love the adjustable volume which comes in handy for providing deeper bass when needed. The auto cutoff function is a plus ensuring I'm not wasting electricity when not in use. I've seen reviews that knock it's power, but the proper source and receiver adjustments it's more than enough.
