Q
does this come with the ceiling mount kit?
ismael  Dec 19, 2018

Not really; though, I suppose you could just use the screws and a nut/washer to hold the speaker in the ceiling but I wouldn't trust it to hold tightly. For installation in a drop ceiling, I ordered metal backing plates (ATLAS 8" Round Hole T-Bar Bridge). These were under $10 each and made each speaker install very sturdy -- would definitely recommend these.

no it doesn't. I just got them and they didn't have any type of mounts in the box. All that came with it was 4 bolts with nuts
