Re: My retirement Home Theater

My my actual measurements are not the same as calculated with my horns - I'm guessing yours will follow suit. I'd be sure that there is plenty of room to slide them back and forth for the smoothest response. ie, my best placement would have been front and rear right corners. Unfortunately I had everywhere else except for the rear corner to put subs.

is the screen wall solid other than the AT Screen? Should be if at all possible. If solid other than the screen, you'll have resonances from the pseudo-cavity and have 2 sets of length modes to deal with.
I was planning on having a 2x4 frame structure for the wall with it all being open... This would be for the 15' part only though as the hallway end wall would be solid (so on the left there is a cavity ). I was thinking of using acoustic treatment on the whole cavity to make it dead. What do you suggest?

Well I will have 5' of depth to play with, which means the speakers can move up to 3' backwards if needed. If I have to I can rotate the subs to make the narrow edge be facing the front screen wall.

Re: My retirement Home Theater

I would look at using the subs as part of the wall have the openings like what I plan to do with my spuds. There might be a way you could frame around them and then they would just be part of the wall.

I originally thought of that but I am not sure I have enough space for them between the center and left or right channels. I think that once we get started I can play around with seeing where they sound the best and go from there. If I go that route then all my speakers in the front should be butted up against the screen wall, correct?

I figure as soon as we get the screen wall framed I will move the speaker in the room 1 pair at a time and run the test signals to see where the need to be to sound best. I was thinking of setting up each pair by it self to get the best soundstage... Mark the locations for that particular pair and then work on integrating them into the room design. Once a pair has been setup, then I would remove it from the room and move on to the next pair. I figure I would do the same for the subs, but I would do them with the front pair in place and without them in place to see how they sound.

Does this sound like it would work? Is there a better way?

Re: My retirement Home Theater

I think you want to do the subs first, but I could be wrong. As for the rest I am not sure hopefully someone chimes and helps.

Re: My retirement Home Theater

Would it cause problems acoustically if I mounted the surround speakers at an angle on the rear wall an then built the upper wall out (at the same angle as the speakers) to make them flush?

Re: My retirement Home Theater

Probably would be OK pending how steep the angle is. Lots of rooms built in attic bonus rooms end up with upper walls angled like that.

Re: My retirement Home Theater

Question: I noticed another forum member used Sheetrock, GG, and then MDF... Is there a reason why we do OSB, GG, and then sheet rock instead of sheet rock, GG, and then OSB or MDF?

Re: My retirement Home Theater

The reason some folks use MDF on the layer closest to the studs is to provide a mounting surface anywhere in the room. Drywall on the facing layer for the smoothest, best looking, easiest to paint layer showing.
