Re: Plenum rated speaker wire?
Is your ceiling an "other space used for enviromental air" as discussed in 300.22?
In other words, does the ceiling act as the return air, or ar the air returns ducted?

Some people think that speakers and wiring don't matter. Same rules apply to the wiring and you may be required to use backboxes, not open speakers. Check with the AHJ.

Re: Plenum rated speaker wire?
Don't forget to use CL2 or CL3 rated cable. Zip cord style speaker wire is not listed for use when concealed by walls, ceilings etc. If it's a plenum than you'll need CL2P or CL3P cable or equal.

Holy cow. And you can bid this way and get work, or is it mostly T&M? Curious...
Re: Plenum rated speaker wire?
To be honest, we use the enclosures for the improved sound performance, both the better bottom end and reduced transmitted noise which is a biggie in 2 story homes. We point it out during the bid process and I think it makes it look like the other guys are cutting corners. I just tell people if you want it done right this is how, if you want it done cheap there are other ways. The few bids we lose purely over cost are probably not customers we wanted anyway. The fact that they are fire rated is just a bonus and second selling point for us.
