I guess we would really know the dimensions of your room to make a more informed comment,but I will give it a shot. If you have a relatively small to medium room, ie a F.R.O.G., You could go this route for about $1800-1900, depending on your local dealer.
3 sets of RB-51s for fronts, side surrounds, and rear surrounds. I am a advocate for using all of the same speakers in this application for timbre matching.
RC- 51 for your center
RW-10d sub.
Then you will have a little money left for stands and brackets
Or, if you had to have floor standers, you could replace one set of the RB-51s with RF-52s. The timbre match should still be good. That will have you at about $1900-2100, again depending on your local dealer.
