OSD 6.5" in Ceiling Speaker Pair 150W, Trimless Magnetic Grille, Pivoting Tweeter, Paintable Grille ACE640

These are great for surround speakers. One speaker had a slight crackle with certain frequencies when I first bought them, but when I reached out to customer service, they promptly sent me a replacement. They sound great, look great, and aren't crazy expensive. Not sure how they would sound as your main speakers since that's not how I use mine, but I know others have.

The build quality is great. The sound is perfect. I am very pleased with the sound and look, the wife loves the trim less design. The best part is the price, very affordable that doesn’t break the bank!Yes I know they are no HiFi speakers, but for my use very worth it.I highly recommend them!!

Super clean looking speakers. Very small foot print and minimal bezel. Magnetic cover which is miles better than the old mesh tucked in to a ring. Sound is impressive for their size. I use them in a 5.1 set up for surround and music. Even a 4” for the center channel does the job fine.My recommendation is to get the adjustable Milwaukee hole saw. I used this and it cut perfect holes. It also has a dust catcher for ceiling install. You have to be careful with cutting since the bezel is tiny.Quality seems great. Not a paper cone which was important to me.Wish list would be star bit screws for tightening down on the drywall. Phillips slip sometimes. Less chance of damage to the cone. Other than that these are a winner for the $$$

We recently had a new home built and at the advice of my builder I decided to pre-wire it for home audio before the drywall went up. I consulted with a couple of retail outfits and got quotes from both. I was really taken back at what it would have cost to go with the systems they quoted, so OK, regroup. I ran across OSD on Amazon and they had good reviews so I planned out my system and pulled the trigger. MAN am I glad I went this route! I was really only looking for quality sound at low volume throughout the house and on the patio. I wound up with MUCH better sound than I was expecting Here is what I went with: 8" OSD cieling mount pairs in living rm, dining rm, kitchen, master bed rm and patio. 6" OSD cieling mount in master and guest bath. OSD volume controls on each pair respectivly, probably could have gotten away with gouping kitchen, LR and DR on one control but what the heck right? I am driving all of these speakers with Dennon DRA-800H and added a Polk 10" sub to the system. This is a two chanel system for stereo only, was not trying to create a theater set up with this system as we have a sepperate room for that downstairs. I do however have a blueray player hooked up to this Dennon and if I choose I can use the home system while playing movies and it does sound really good even though its just stereo. Bottom line, at the cost of these speakers compared to some of the other brands that were quoted to me I am extremely impressed with the sound. Decent base even with the sub turned off, very good mid range, good highs and more than enough volume than I will probably ever use. If we ever move again I would not hesitate to replicate this system all over again. It might be my favorite feature to my new home. Great work OSD! Theater system review coming, all Polk & Dennon.

I got the speakers so that I can replace the tool Vizio speakers that came with my surround sound system from Costco. Not a whole lot of information out there if these would be great replacements, but they did the trick! The sound is good, and it connected to my surround-sound perfectly. Would buy again!

Pieces of crap; the screw/levers that are represented to hold the speak in the drywall are cheap and fall out of their guides into the wall or the entire crew mechanism broke away from the speaker. I hade to use calk to hold the [2nd] speaker in the hole I created in my drywall. I only needed one speaker [for a bathroom] and after the 1st one broke, I attempted to use the 2nd one and it broke too. I regret wasting my money on these.

I have an old 5.1 surround system with small speakers and a sub. The receiver died some time ago so I replaced it recently with a 7 channel receiver for a 5.1.2 setup and was looking for a small pair of speakers to install in my acoustic tile ceiling. It is a low budget system but now I can enjoy Dolby Atmos movies and music better.

Won't be able to fire these up for a few more weeks, but wanted to start a review to possibly help others. The mounting screws for the ACE400 have very soft heads. I rounded a couple out on my first attempt to install. I then tried running the screws in on an uninstalled speaker and realized that the arms that swing around and grab the back of the drywall do not stay plumb and cause binding. After tightening each arm completely then backing back out uninstalled, I avoided any further rounded off heads. It seems that running them in gets them properly threaded and makes them far easier to install once in the ceiling/wall. I'll add to this review once I get them hooked up.
