Ok so so far i love my system! =] i was wondering would going from rti a3 to a'5s be a major diffrence?! this is all ht...so i was wondering should i go for rtia5 for better midrange?! or does the a'6 take the credit for "vocals" or should i shoot for the a'9s wouldnt want to blow alot of money just want a honest opinion!my sub will take over lows perfectly!
