Question 1

Do you need a speaker box in the ceiling to mount these or do you just cut a hole in the drywall and install them?

Accepted Answer

Its been a while since I installed mine but I do recall the instructions telling you to allow a moderate amount of space around the speaker; something like 1 foot by 1 foot.  You do not specifically need a speaker box but your ceiling construction will affect the acoustics so if you find you have no bass, you may need some type of enclosure or baffle behind the speaker.  I have four of these speakers installed in a 8 foot flat ceiling which has my attic space open to it and they sound great; one speaker mounting hole is secured to a 2x4 attic beam and the remaining mounting holes are secured to just the drywall.  I left the fiberglass insulation in the attic so that it rested on the back of the speaker and again, the speakers sound really good.  I also have a 10 inch subwoofer in the living area to handle the real low-end sound but these speakers provide a solid thump which sounds great.

Question 2

Has anyone used them in a home theater, preferably in an Dolby Atmos setup?

Accepted Answer

Using 4 of them in a 7.2.4 Atmos setup and they work perfectly,   The tweeters are even adjustable so you can point them as I had to do since my ceiling is vaulted hip style.  Everyone even the least technical people who never heard of atmos of dts-X walk away impressed.

Question 3

\Which makes a better frontspeaker set up.  3 or these or 1 MTM with a 6.5 or 8 for left and right?  How about these for rear speakers too.  I like the idea of 5 identical speakers, but not if this isn't a suitable main (with a sub of course).

Accepted Answer

I went with 8" for front right and two rears and the dual 5.25 for center.  If I were to do it again I would have done two 8s for the center.  The duals sound good but need a little more of the lower frequencies

Question 4

Micca doesn't make towers with 8 inch drivers. I was thinking of buying these and building wooden towers using mdf or something. Bad idea ?

Accepted Answer

If you are wanting a two way system with a single 8" and tweeter, it should work fine.  I'd stay away from any kind of venting unless you have reliable Thiel-Small parameters, but I would definitely recommend stuffing the box with AcoustiStuff or similar.  I don't recall if Micca published T-S numbers for the woofer, but since it's made to go in a wall, I presume it's designed for a fairly forgiving infinite baffle alignment.  Good luck!
