Thank you very much, two cables. Yes, I guess I'm expecting too much out of it. I would like to replace it with the Klipsch Synergy 12. I've seen videos on youtube of people who have done it, but I just don't know how to.

Doesn't seem to be any issues with cables... Do you know who I could ask that would know how to replace the subwoofer with a different one?

Sounded fine, no issues.

Also... I feel like something is wrong, because there are so many rooms about how insanely powerful the sub is, but when I have it up too high it just makes a rattling sound like something is wrong with it. I know it's not blown, but...

OH yeah. I've tried max volume, which seems to make the subwoofer sound like crap, I've tried bass boosted songs, which makes the sub sound like crap, and I've tried maxing out the sub with about 60% volume, which sounds okay. There is only bass control on the right speaker, I think, which is up all the way.

Thanks for the response. It's way too little; I want stuff in my room to rattle.

Edit - It is possible, I just need to know how to do it.
