1 Question & 1 Answer
from Colorado asked:
November 15, 2020
Hi, this looks like a great enclosure for some Klipsch CDT-3650-C II speakers that I am considering for in-ceiling in my living room below a couple bedrooms.

Can you give me a sense of how to install them. 

Do they come with a template cutout for the ceiling drywall, and some sort of mounting bracket? It would be nice not to have to open up the whole ceiling.

How do I mount them to an adjacent joist and keep them stable and free from too much vibration on the joist and subfloor above?

Do you have instructions you can share, a photo guide, or a video?
