The MC6-HT is the angled version of the MC6. By designing the speaker with a fixed tweeter and woofer angle, we were able to tune the performance of the speaker far more accurately than universal pivoting designs. The MC6-HT is recommended for applications where the listener will spend most of their time not directly underneath the speaker. For example, when being used as the front or center speaker in a home theater, the listener is typically around 10 feet or farther away, yet typical in ceiling speakers are pointing straight down placing the sweet spot directly in front of the screen. By angling the drivers towards the listener, a very noticeable increase in performance is realized. All MartinLogan Motion CI Series speakers feature our signature Folded Motion Tweeter or FMT.

I have the SLMs for my LCR and needed surround speakers. My couch is against the back wall and I didn't have room in the walls to run wires. Since I was limited in options and my wife didn't want large speakers, I decided on the ML in-ceilings. Before these became available, I tried the IC3's. I connected them to my receiver to see how they sounded with the SLMs and found them to be flat and inefficient. I returned them in favor of the MC4s. The MC4s were a huge improvement. Having the ribbon tweeter, the sound is much brighter and more efficient. They blend in much better with the SLMs. With a small midrange woofer, I was realistic about the expectations. Overall, they sound great. My only complaint has to do with the installation. The mounting tabs were not designed for thicker ceilings. I had to go in the attic and chisel out the slats in the ceiling to get the tabs to turn and grab. This was extra work I didn't expect.

Sounds great for ambient usage and can get decently loud. Especially nice for the size compared to other larger options.

I have the ML motion bookshelves, center, and 5 1/2 surrounds. They are some of the best speakers I've ever heard, and in my opinion well worth their price. These in ceiling speakers however...are not like the rest. They're just not practical given their extremely limited range. Nothing sounds "complete" coming from these speakers alone. Deep voices, drums, a train, anything that needs a full range just gets cut right off at the mids. The mids and highs coming from the tiny speaker and folded tweeter are fantastic...but again, everything sounds "cut off" off by the limited lows. I was planning on using these as Atmos height speakers, but returned them because I don't even see them as being useful for things like helicopters flying overhead in the Atmos height speakers. If you're cutting your ceiling or wall to install a pair of speakers, definitely look elsewhere; especially for this price.
