Planning My IB

I'm currently building our new home.
We are nearly done so it is time to start building the Theater Room.
The only feature which needs to be mentioned for the false wall (IB) is that there will be a vented louver door in the back right for an entrance. I beileve I have read in other posts that such a door would allow the space behind it to be counted for its 10 X VAS.

By the looks of the plans and pictures am I on the right track?

Re: Planning My IB

If you have an 8 foot ceiling, then the Component Room has 276 cubic feet. What is the Vas of the AE 18's?

Re: Planning My IB

The two configurations (illistrations below) I am think about is the woofers in the wall or the manifold at the center.
I will be using two AE 18"s.
Is there a difference in output, sound and the amount of air they push out between these two configurations?

I prefer the woofers in the wall it allows the screen to be dropped 4" which will allow a diagonal screen of 110.

If there are any manifolds designs which will not exceed 15" of height this might be more of a consideration. The center channel speaker is a Onix Rocket 200 and will be built inwall perferribly.

I'm also not looking forward to do the eq wizard. Is this absolute necassary? It seem just a little overwhelming right now.

Please look at what I wish to do, give me some suggestions.

Re: Planning My IB

I'm not sure what effect the vented louver door will have on your IB as the door will allow the backwave of the woofer to reach the front wave. You might wind up with a cencellation issue. Hopefully someone who knows for sure will chime in here.

Re: Planning My IB

What I would do if I were you, is frame in a wall by your right main speaker and build a door somewhere down the right wall or even around the corner if you could (dont know what your whole floor plan is) and kick that 3' wall for your back wave room and keep that open. Also I would only use a manifold with your drivers.

Thats what I would do. Hope this helps.

Oh yeah those numbers for the ib15's dont look right.

There is only a staircase to the right, thats "FILLED" with tanks, and pumps. The opening is not movible.

Man,,, I put that wall in there just for the IB sub,, swore that was the way to proceed.

Am I to understand that the vented door will not work for my vas. The 3' room is insulated, with r21, and rockwool all sides and ceiling.

Any more suggestions of guidance will be appriated.

Thanks for the help.

It will work for the Vas. The problem is the cancellation that will occur when the back wave meets the front. Trevor's suggestion to frame in a wall was to separate the back wave from the front.

Re: Planning My IB

Maybe, I need to give more information.
The vented door, opens from the bathroom. The bathroom will be closed in, and entrance to the theater room will also have either an acoustical curtain or more likely a door.
I will redo my sketch up to include these rooms for a better layout.

Once again,, thanks for your input and interest.
