MitchOK Theater Construction Thread

I am sure Bryan will give a much better answer, but yes...essentially by enclosing them (I have Klipsch bookshelf speakers) it changes the acoustics and doesn't allow the speaker to "breath"... as opposed to a speaker that was actually designed into a cabinent. I took Bryan's suggestion and significantly oversized the shelfs that the speakers will sit on and made sure the center speaker shelf was completely open. I am sure it isn't ideal, but I don't really want the speakers on the floor or on stands away from the wall where they would likely sound better. I have traffic flow issues in the room. If I end up with any issues, I guess I plan on dealing with it by use of baffles, sound deading material, or other solution depending on the issue encountered. My sub will be out in the room so that isn't an issue. The screen is only about 5-6 inches at most in front of the speaker plane... so I don't expect an issue there.

Going tomorrow to pick out granite countertops... woo hoo... getting closer.

Any time you place a speaker that's not designed to be in wall or in a box, in one, you're going to substantially change bass response and impact the baffle step compensation that the speaker designer built into the crossover.

If you must put it in a cabinet, the balance of the cavity it sits in needs to be filled with insulation or absorbtion of some sort to prevent lots of nasty resonances and ringing. That won't help the baffle difference but will help with the bottom end.

As for the screen, optimally yes. But it also depends on the off axis vertical response of the speakers. Ear level is good. A proper screen though, will also be set up so seated ear/eye position is approx 1/3 up from the bottom of the screen.

Great job! I love the retractable projector mount. Looks like its going to be a nice room.
