Yeah I know I'm too late for this but......

QS4 v/s QS8
for only an extra $50 per speaker you get:

400 watts Max Amp Power v/s 175 watts
Freq Resp +3dB/ -9dB (Hz) 65-22K v/s 100-22K
Woofer Dual 5.25" v/s Dual 4.5"
Weight 11lbs per speaker v/s 5.5 lbs

Not my money but it seems to me that this is a case where a little $ buys a LOT more product.
