I've never had a sub before this ep350, but I can't find fault with it. My friend has a sub (I think its an Energy since that's what his mains are) that doesn't sound any better. It took me a little while to find a good spot to place mine, but that's about it.

Actually, it would be cool if it had a remote. And the grill shouldn't come down all the way. I think I must have broken the plastic plugs that connect the grill to the sub by tilting it forward to better access the controls on the back. No problem though, Joe sent me out a handful of replacements promptly and free of charge.
