I have just upgraded my system from the RM7600 to RTi A1's in the front (bi-ampd) and RTI A4's in the rear with the CSi A4 center.
The sound is simply no comparison.
I have the PSW450A sub which has been a killer and still works perfectly. I have the option of a free PSW10 or applying the cost to another sub.
The DSW PRO 400 looks to be a fit but just wondering if the bass is an improvement over the PSW450A.
Need feedback it is greatly appreciated..
