Cannot do 5.1 then does 3.1 make a difference or just stick to 2.1?

I agree with big_greg that you could look at the Legacy Cinema HD.  If money is not an issue and 10" is not too high, I would probably look at the Legacy Silverscreen HD instead, to keep the ribbon tweeter voicing that would match your Aeris.

I don't know that I would recommend the Klipsch RC-7 because the horn-loaded tweeter is going to have a radically different voicing.   If you are going to look at different brands, I would look at a Dali Epicon Vokal first, because it uses a similar AMT ribbon tweeter and I think the voicing will be a lot closer than Klipsch.   However, the Legacy Silverscreen is still going to be the best.

Thanks all I decided to get the center channel and going all the way. Need to fix furniture later. Thanks again

My two cents: Center for movies with your setup. Music, keep it two channel for your setup.

mental ! Yes absolutely.
