Hi guys:

I need some help. I bought two 602s3s last year with the large LCR600 center, and am using leftover deftech procinema 100s for the surrounds and backs.

I only watch tv/movies (no music), and have a room that is about 14 wide by 25 long - it's a dedicated home theater room. The speakers are being driven by a new onkyo 705 (no separate amp), and the video is a panny ax100. My sub is a deft tech prosub 80

My dealer has a one year upgrade program, so I can apply the purchase price of the fronts/center to whatever I upgrade to.

My question:

Is it worth it to upgrade to 705s with the matching HTM7 center? My 602s/lcr seem much larger - I know size isn't everything (ha ha ha), but I also don't want to waste money on an upgrade if it really isn't. Should I get 684s or 683s instead of the 705s?

We tend to listen at moderate levels. I'm more of a video guy than an audio guy, so I appreciate your help. If the 705s have crystal clarity at relatively low volume levels that would be a big plus for me.

Any thoughts? Would I be better off just spending the money on 600s or 686s for the surrounds/backs instead of upgrading the fronts?

I'd appreciate as many thoughts as people would care to offer.

I'd get some 683s.
