I started out the same way you did. I have the RF62s, RC62, and RW10d. i promise the RW10d has plenty of thump and I have it in a 31x15 room. I have it +4db on my receiver and just default on the sub itself. I like alot of bass also. Would you rather spend alot more money on a sub or would you rather save some money, turn it up a little and buy you something nice like a RC62. The RC52 is not the matched center with the RF82s anyway. trust me I have listened to them with music and movies. If you have the room on the walls i would say go for the RS42s. Unless you would rather go with something like the RB61 and put them on stands? up to you really. i like the ceiling mount speakers, out of the way and concealed. sounddistributors.com has some very very good prices on anything you want.
