My design goals for my dedicated HT room are:
1. Select HT seating and placement
2. Sound diffusers/blockers/traps
3. Complete woodwork (crown molding) & decorations
4.
Then start upgrading everything...
a. Start with new sub (decide on what type of sub) - I need to feel the "boom"
b. HD DVD player
c. Receiver
d. Speakers
Pitfalls:
I was given some bad advice (wasn't a membe here yet) and didn't insulate any of the room while tearing down and rebuilding...

On my next windfall, I'll just have to start over. Might take down the false wall with the HVAC ducts, re-route and open the room up for wider seating.
Future plans:
Get all my my Theater sources calibrated: Projector, 55" Hitachi, 42" Plamsa, 34" Sony Flat Screen...
Upgrade my Surround System in the Gameroom, move the Onkyo to the Master (oh, add TV in master.)
Besides the funds and time, I'm just about ready.
My neighbors system consists of a Mistu 3000 Projector, the screen is stretched fabric, I think his receiver was Onkyo. He has Dish with the Sports package and the Theater is primarily used for everday watching and all Sports events. His picture is very clear. His Velodyne sub thumping from the rear tops off a very nice Theater Room.
I'm glad everyone came and I hope you enjoyed your visit to my humble abode. I'm looking forward to our future visits where can get some hands on with some new projects.
