Public Theaters have lots of appeal for me as well. But I hope to have a sillier feel in my room. I have no doubt that my room with sound better, but a 96" screen is hard to compar to a 40 ft screen.

Then again, my room is small enough that my screen size should give you a similar feel. And my movie can pause if I need to use the washroom!

 

Im definately watching this, I have some serious nodes in my theater room, Interested to see how you solve your issues.

 

going for 5.1 or 7.1 setup?

 

I'm sticking with 5.1 for now. I haven't heard any real advantage in the addition of extra speakers. I may switch this in the future, but not for now.

I will be building all the speakers for this system. A serious advantage IMHO.

 

a lot of the great movies make use of 7.1

 

Most movies take advantage of the extra channels these days. Dolby has the ability to do 10.1 last I heard, but the advantages are minimal.

MTA, what problems are you having?
All rectangular rooms will have three main problem frequencies along with multiples of each of those. There is nothing you can do to prevent them. What you need to do, is try and control the peaks as best as you can. This can be done in lots of ways that I will be going into when I start talking about my room design.

 

my bass frequences have severe cancelation( really bad standing waves )

the best viewing position has the absolute worst sound position! I mean the worst.
the best is only 7.5 feet away from the screen ... on a 106" screen... yeah you know what Im talking about HD headache

Ive even gotten to the point of setting the subwoofer directly beside my seat inorder to have some bass in my movies!! I get a bit of better response when I cross over all my speakers at 80-100Hz but the sound from my sub becomes too boomy

it's a real pain in ****... Ill draw you a room layout with dimensions after I watch SAW - The final CHapter... this is goin to be gross sitting to it that close lololol

Oh i have been reading a bit about treating my room... but right now I cant do too much in my garage to build, alll my outdoor furniture is in there

 

I'm definitely intrigued with your project, fozzz I'm subscribed I'm also curious how you are going to go about the acoustical issues, so good luck (not sure you'll really need it, but just the same ) and keep us posted

 

Sub bass is the hardest thing to get right in a room. Bass traps will help you for sure. Every corner in a room will cause problems. The rear corners should be your place to start. Bass traps need to be LARGE! My room will be using the entire rear wall as a bass trap ( ther will be more than just this one). And it's 14" thick. So imagine a 7th high, 12 ft wide wall of absorption.
Some people will treat a room with curtains, and egg catron foam, or other thin items. Too much of these items will hurt you more than anything. Thin treatments will absorb only mid and high frequencies. Sub bass will be unaffected. So you can imagine how this will hurt your sound.
One solution to poor bass response is using multiple subs. I'm using two subs for this reason, but four subs would be better. You would need to mount one sub along the mid point of each wall. This helps to minimize the comb filtering problem that you're having.

 

also pics are always nice to see espcially during process and making of the room.
