I would definitely agree with this. Though $600.00 for twin RW-12d's is a killer deal, and really hard to pass up if you are subless, a better quality sub will do wonders for your system.

I know these subs leave a lot to be desired but since the addition of xt32 they are really sounding quite good. (I actually got 2 new for 300.00 total) My biggest challenge is the half wall directly behind the sofa. If I could just add a couple of rb's far enough back I would call it a day with 7.2
Maybe a couple of side surrounds would work but was just curios as to what benefits front wides / front heights would add to the movie experience...
