The builder of our house put two double load-bearing studs in the middle of the media room wall where we want to install an in-wall center channel speaker. Would installing a box frame with double 2x4's for the top and bottom plate to distribute the load as shown in the picture below compromise the short or long-term integrity of the load?
The orange box in the picture is where the speaker would go.
This room in the only room upstairs in the 1 1/2 story house. There is attic space behind this wall up to the diagonal studs on the left side. Above and behind the diagonal studs is outside/roof/bricks.
I wouldn't do the work myself, but before I reach out to any contractors, I wanted to get the folks' opinions on this forum.
If it's too much of a risk/hassle, I may opt for a different option for the speaker. Such as mounting it on the wall or a shelf.
UPDATE: Well I just found out the builder has already hung the sheetrock along with mudding and tapping it! They won't allow me to fur it our at few inches as K H pointed out below. Which I think would have been a good option.
Now I am back to the drawing board. So it's either cut the drywall or go through the attic to access the studs to put in re-enforced headers (a couple of 2x10's or 8's).
I've reached out to a residential structural engineer to get his opinion. I'm waiting to hear back.
