I am ready to get rid of my cheap r50's for the rears and looking to upgrade. Im looking at the monitor 70's but leaning towards the rtia7's which I know are probably much better. My fronts are the csi5 and rti150's. What do you all think? Or should I go all out and get the rtia9's and move my rti150's to the rears. Which in fact are alot like the a9's just a few models old. I probably cant afford that option though. Help me decide please.
