What can I get for $600? 2 towers and center

[mj79]

I have a pioneer vsx819 receiver and an all Polk setup. I have 2 subs on the way ( a 12" and a 15" aa hdsub ) but I have a feeling thesesubs are going to over power my current setup up front of a Polk cs10 center and tsi 300 towers. I see there's tons of good deals people find here from all over the net so I'm looki g for suggestions

I have about 2 weeks left on my 30 day return policy from best buy so any suggestions would help. If theres a good dual 6 1/2 speaker tower or 3 5 1/4 that would be good cuz it really seems these speakers seem to struggle when turned up


Are the monitor 60s much better than what I have? Cuz I see alot of people running them and they seem pretty happy. So any suggestions of around or if possible,less than $600 thT wouldbe great. Thanks again

I believe my receiver is rated for 110x5 with the 1khz rating. So maybe dri ing all 5 channels maybe right around 70-80/ per channel?
