There are installed systems all over my work.  Most are Meyer power speakers.  Typically an outlet box is put near the fly point.  Then a flexible cable (not sure if it's SO or SJ) goes from a twist lock at the box to the PowerCon on the speaker.  Tie wrapped to the hang cable along with the signal cable.  Probably 20 rooms on the campus set up like this..

I've seen this too. SO for about 30+ft from the speaker hang to the nearest installed via conduit outlet.

Obviously there's some leeway, but I could see how running SO along a building structure instead of along the aircraft cable hang is vastly different.

i don't think powered speakers in a fixed install make sense.  Even after the extra trouble of getting them installed, WHEN they fail the electronics that need service are 30 ft in the air.   I like a Amp and DSP in a rack where I can install a backup in a hurry.   I've had to do it on Sunday morning between the beginning of practice and the service.

A dance teacher in my school district bought a set of 4 medium sized powered speakers for her Dance Gym  (no sports balls thrown in here). We (the A/V dept) mounted them on the walls about 12 feet up (easy to reach with ladder) and wired them to a wall plate that connects to portable mixer/playback rack. Tested them using extension cords. Actually sound pretty good for cheap stuff in a gym. Now we have to wait for the Electrical Dept to get around to installing conduits, boxes and circuitry to the 4 speakers.

Electrician installs and terminates all 120V (line voltage) equipment. Assuming you have a control system, I think the best way is for you to provide him these to install:

That way you can turn the speakers all the way off, which has been a sticking point on some of my permanent installations with powered speakers.

What does that do to the total price?
