I started shopping for these almost a year ago when our house was under construction. I went to Best Buy to compare their in ceiling speakers. The Best Buy person recommended Sonance speakers, but the DI 6.5Rs just sounded much better. I felt the Sonance MAG series speakers sounded very muddy. I ended up buying 4 of these for the great room. First, installation was a breeze. I was a little nervous taking a drywall saw to my new ceiling, but the template made things simple. I had run the speaker wires before the drywall went up, so that part of the task was already complete. I did use, and highly recommend, XTC 10 inch speaker baffles that create a protective cavity in the ceiling. With the holes cut, the baffles in place, the speakers just slid into place and the 4 tabs are holding the speakers nice and snug. Just don't overtighten the screws. The magnetic grills snapped into place, leaving a clean, stealthy installation (see photo). I hooked these up to a Yamaha RX-V4A. Not the highest end AVR, but acceptable for my needs in this room. The sound is already good and I am sure that will improve as they break in. My only concern is the bass. As you can see from the photo, the room is rather large. I am considering adding a subwoofer. I am not a big bass person, I keep my subwoofer in my theater room pretty low. I just feel a subwoofer will help these speakers fill the room with the low end. Overall I am very happy with these speakers and I will be installing two more of these as my Atmos height speakers in my theater room. I knocked off 1 star in value, due to the price. Perhaps it was the sticker shock of buying four of these at once.

Sounds good, can play loud and it's clear. Lacks low end ulbut that is expected for the size/location.

I used these as ATMOS ceiling speakers and they do not disappoint. Mounting was easy and the mechanisms are much higher quality than other speakers I have mounted. The magnetic grilles make removal SOOOOOO much easier than the old paper clip hook method. Very clean, flush look in the end and great sound quality. They are a bit pricey, but it nice to have the sound matching with other Definitive speakers.

Sounds great. Have them installed in ceiling. Easy to set up directional tweeter is easy to manipulate.
