Thank you all for your comments. You have given me A LOT of things to look into. So far I have been VERY impressed with the Adam Audio reviews for their GTC series. Triads sound amazing as well. While "best" is a subjective term, I wonder if the GTC line is comparable to the JTR's and the Seatons? The Adam Audio review was very strong. That said, I'm not sure Adam's subs are equal to either the above mentioned JTR Captivors or Seaton Submersives. Anyone have any thoughts on this?
As for speaker placement for my rears, unfortunately my room cannot accomodate in-wall rears due to an uneven back wall. They will have to be in-ceiling if they are to be equal distance from the screen. Even if this wasn't important, I still could not accomodate in-walls - there simply isn't space for them on one side of the room.
Yes, I am putting in effort to soundproof the space. I have used (and please don't laugh at me if this is just worthless marketing B.S.) THX approved drywall through-out. I used two varieties, one 5/8's thick and the other is over an inch, heavy as h*ll, and expensive to boot. In addition I've used some reddish and bluish soundproofing putty to seal an extra layer of drywall in some ceiling areas. In these areas there will be an air-pocket separating drywall layers. All in all, I think I've done an amazing job, especially when you consider I have no idea what I'm doing! Of course it's probably all wrong. I know that. But at least me it's mine all wrong and say what you will, there is a certain satisfaction in that (for me, anyway.) Like Frank, I can say, "I did it my way..."
I will certainly look into all your suggestions and do sincerely appreciate any comments on anything I've written here. I really do. You are all truly a bunch of good eggs.
