hi there guys, im finally looking at buying some new speakers too finish off my system. and was looking at the b&w 600s3's i think they are about £100 each,and are not too big and look great. would these be suitable for fronts and rears as our room is not that big approx 13x15? also the b&w 60 center speaker about £200,too go with them. and finally, the vx10 sub roughly £200, any advice please guys i have about £800 too spend on my speakers. i will be using a denon2801 amp. thanx dudes!
