My current plan is no more display tech, and my next project is a HT after we move. I've told the wife my only real request for the next house (build or buy used) is enough room for my HT project.
Here are a couple of calculators I thought were cool.
My goal is 100" range 16x9 screen, with 6 chairs, 3 in each row with two rows. Probably plan to spend about $4000-5000 on the PJ. Now I just have to find the house
Seriously, it's a 3-4 year plan, but my current setup will stay in place until that happens.
