ceiling speakers and air escape

[PoorOwner]

I am considering a couple of ceiling speakers I have already acquired, a good brand and not some $30 one.

But I am concerned fumes or gasoline smell escaping through up into the second floor?

The cone had no holes so the only concern would be the rim of the Speaker flange?

Per most codes it is a no no for the reasons you state above. But there are covers that are air seals you can install that will provide vapor barrier and air infiltration but you should really make a fire rated sheet rock box. You cut holes in and it is a direct fire path.

I might make a plywood box to house it then, still very low profile. The speakers sound good in a sealed box of any size.

Something like that might work. I'd can foam around it to hold it and improve sound quality. But I can foam EVERYTHING.

Tthe ceiling of a garage under living space had to be fire rated. Speakers of any type in the ceiling are a no-go without a fire rated enclosure.

Yes I thought I did not want any of the issues

I am going to cut a triangle piece and install the speakers at the corner but vertically so it has a built in look once painted

If you want to retain the fire rating make an enclosure out of 5/8 sheetrock. It also has good mass so it's good for preventing sound transfer through the second floor and will improve the quality of sound below.

I installed can lights in my garage, I had to box them in with drywall.

Why not just build an enclosure for the speakers and hang them from the ceiling?

Uh, you can't have holes in the sheetrock since it is a fire block. I'd surface mount the speakers.

Does anyone read all of the posts in a thread before hitting the reply button?

The OP stated he's going to be building enclosures to prevent cutting into the drywall.
