The Marty's mentioned above are a great value DIY build, and I agree if you don't mind going the DIY route and have somewhere to put (hide) them, like behind a screen wall.
If this is going in a living room where you have to make it wife approved, the subs you mentioned are all highly regarded choices. I haven't heard all of the choices, but I would probably go with the PSA, but the PC-4000 gets a lot of love too. Rythmik is supposed to be excellent for music.
