Creative placement of IB

[zeus00]

So, I've been thinking about were to place an IB in my basement... and I had a creative thought.

My basement is comprised of my HT area - and the other half is unfinished (HVAC, washer/dryer/etc). However, in my HT area, I have a closet.... It's mostly just long term storage and a water meter - I rarely get into it because it's partially obscured by a screen wall -- w/speakers behind it.

So, my question is, could I build an IB array in the closet - and use the floor joists above to couple it to the unfinished basement?

It would basically be a medium size box (closet) coupled (via ceiling) to the "infinite" box (unfinished basement).

I imagine that it's going to come down to the surface area of the openings in the ceiling joists and whether it constricts/colors the sound?

I'm thinking surface area of the openings in the ceiling would be 6ft (depth of closet) x .75ft (8" tall floor joists) = 4.5 sq ft....

So, closet is roughly 117 cuft, ceiling volume between closet and unfinished area is 31 cuft, and unfinished basement is 1300 cuft.

A crude not to scale image is attached. Closet is top left, with IB array in the front, orange/yellow represents IB volume (with the blue being the floor joists.... so for that area -- it would NOT be the whole height, only the ceiling.

Does this sound crazy?

The idea is unrestricted free space behind the woofers. So using ceiling joist space as tubes to connect the closet with the unfinished area is a no go.

You maybe able to use the closet by itself or there maybe other options

Do you have photos of the basement?

Yeah, I had a feeling that would make it a no go.. I think that the volume of the closet is too small... I should measure it just to double check.

I'll get some pics.

I can still put an IB manifold or array in the unfinished part of the basement - just a little concerned about the WAF.

I actually have a 6-8cuft sealed sub underneath the stairs -- which I could replace with a manifold -- but have read that behind the seating is the worst choice for IB placement.
