Ok, so I have some RTi A7's as my main speakers, and I gave my parents my old RTi8's (I got the A7's on a deal from American for $800 for the pair about a year ago) when I got the A7's. The RTi8's replaced some huge Optimus Mach 2's, and my mom appreciated the visual change from huge boxes on stands.
My parent's living room does not really have room for a sub or any good place to put one (plus my mom will start complaining about more room being taken up), so to help my folks speaker setup and improve bass response, I'm giving them my A7's, and I'm taking the RTi8's back.
I was thinking of getting some A5's to replace the RTi8's, because I have a kick*** sub, so I probably don't need something that can play real deep. Is there a huge difference between the RTi8's and the RTi A5's? I know it's similar components in a different cabinet. I'd really like a pair of A9's just for the sheer awesomeness of them, but I can't justify the money for them now. And, I only have a Yamaha RX-V861 so I don't think it's high powered enough for the A9's anyway.
