Audio Speaker housing in cement
(OP)
Good Day Engineer Gurus!
I am in need of your concrete/structural expertise please.
I need for some audio speakers(6 1/4 diameter) to be encased into an 11" floor of cement, in between an 8x8 square of rebar somewhere in each floor. Need to be able to screw into housing in anyway to hold the speaker in place. These will be throughout each floor/ceiling going into condos.
I need the housing for each speaker to be able to handle the pour of cement and possibly stay in place. Cost is a major issue(over budget) if we use metal don't want any rust issue, only using a clear sealant on exterior of concrete.
I am looking at Sono Tubes, but they are cardboard?
Once I come up with a solution, I need to present to a group of architects. If you have any questions, feel free to write me.
Thank you in advance for all your assistance!

RE: Audio Speaker housing in cement
Does the speaker sit just partially into the floor (i.e. do you need the entire 11" of depth for the speaker?)?
How will the speaker be wired?
Is this new construction?
You mention rebar at 8" on center in each direction, what size is the bar?
Some kind of custom sheet metal form to get a round hole or pvc pipe.
I am not sure how small of a sonotube form there is, but I am sure that they don't come in fractions.
Are you asking whether this is possible or asking for design advice? If the latter, contact a local engineer or the actual design engineer for the floor.

I've never done anything like this. But take a look at www.mcmaster.com, and look for item # 8261K25. It is a PVC NEMA enclosure, 6.9" square X 4.6" deep (these may be outside lid dimensions, so it might be a bit small yet). Look on the catalog pages before and after this item for some other similar stuff.
Another alternative is to just build a wooden box, cast it into the concrete, and leave it there.
Check with whoever is designing the rebare- you can probably shift those bars over a bit right around the opening if you need to.

I expect a structural engineer to not do that.

Buy a dictionary, keep it nearby and USE it. Webster's New World Dictionary of American English is recommended, and Webster's Collegiate Dictionary.

It's concrete, not cement.
