## Description

With the ACE670 trimless in-ceiling LCR speaker, you'll get imaging and staging that would be lost with regular, down-firing ceiling speakers. Features include a sturdy 6.5” Kevlar woofer fixed at a 15° angle, a 1” aluminum dome and a 150W power handling. You can even use them for Dolby Atmos front, rear and side surrounds in a 5.1 or 7.1 system.What Are the Benefits of an Angled In-ceiling Speaker?The angled speaker is a real problem solver because not every space is ideal for custom home theater sound applications. The angled in-ceiling speaker features a 15 degree angle for the mid bass driver plus a pivoting tweeter for placement flexibility. This speaker can be part of three piece set to handle the front stage of the surround system when both on-wall and in-wall are not a favorable option. The angled design allows the ideal placement in the ceiling closer to the wall just above the monitor.

Review: Bought this to replace a 10 year old Parasound C65 that went bad. At $70 for a pair, I didn’t expect much from the OSD compared to the $350/pr Parasounds. But I thought I might scavenge the OSD for parts to make the Parasound work again. Got lazy/busy and just removed the Parasound altogether and installed OSD, which was a perfect fit. Much to my surprise, the OSD sounded just as good as the Parasound! This is a great in-ceiling speaker for a fantastic price!
Review: Great sound and easy to install! I installed them in a light suspended ceiling, and they're quite heavy speakers so I had to build support pieces for them. The screw tabs on the back work great and tighten up nicely. They look great once installed and I barely notice them on the ceiling. Sounds great!

## Questions & Answers

**Q: it says 6.6" but require a cut out of 8 1/8 which one is correct? is there one which require 6" cutout?**
A: The ACE670 has a speaker diameter of 6.5 inches and requires an 8-1/4 cutout. The ACE870 has a speaker diameter of 8 inches and requires a cutout of 10 inches.

**Q: Can I use these in my 5.1 system.. front l/r, back l/r and center?**
A: They are meant to be used more for back l/r, and that's how I'm using them.Probably would work for front l/r, not so good as a center speaker. Primarily because front l/r and center speakers should be at listener's height, not on the ceiling.

**Q: Why is this speaker, that’s sold by osd, $149, when the price on osd website is $99.99 for same speaker?**
A: When you purchase more directly from the manufacturer, you're able to get a lower price.

**Q: How much do they weigh?**
A: Around 10 maybe 15 pounds.

### ⭐⭐⭐⭐⭐ Review
*by J***D on 2 December 2019*

I've never been a fan of in-wall speakers but had to get them for my new house. I went from B&W bookshelfs, a b&w center, and paradigm bi-polars for my sides and rears. I can't compare these to that, I only mention for my experience in audio quality. General: For a hundred bucks a speaker, these are great. I like that they are directional, they're easy to install, and appear to be well built. The speaker grills are neat and clean, and overall the look is pleasing and simple. Audio: Good for movies and shows in general for sure. Clear, crisp audio, sounds how it should in my opinion. Music is another story. I'd only give these things a 6/10 if you want to listen to music and experience a wide tonal range. I found the lows partially muted and the mids somewhat dull, but I corrected this running Denon Audessey and adjusting the EQ of each speaker. Still, there's only so much you can do to manipulate audio after it's built. But again, I use mine mostly for movies, and I'm plenty pleased with them considering what I paid. Customer Service: This is kind of "meh" to me. I ordered six speakers, and four came in that were the downgraded version with worse bezels. This kind of aggravated me because I ordered six of the exact same speaker at the the exact same time, but whatever, people make mistakes. Still, I contacted them and they were indifferent to the situation and didn't offer an apology or anything. I ended up order four more and returned the inferior ones when the new ones came in. Then, I had one speaker crackle badly when the volume was turned up. After emailing them, they said, "must have happened in shipping, you're under warranty, just order another and return that one or send that one back and we'll repair it and send it back." Okay, that's decent customer service, but why am I ordering SIX speakers and having trouble with FIVE of them? I mean, even on the new four, I had to tighten screws on the construction of the speaker on two of them. Screws were in, but were not even remotely tight. Barely even threaded. As far as I'm concerned, for a hundred bucks, I can tighten screws. But I shouldn't have to, I wasn't told I'd have to, and to add in the crap service, just make sure you know what you're getting into before you buy these. You're going to get some great speakers at a great price, but you may have some work ahead of you if you're ordering a lot or need to install in a hurry. Here's where I have to justify the five stars: My b&w's were $800 a pair, and the paradigms were $1200. These are $120, and sound impressively full--for in walls. If my bowers sounded like this I'd return them. But for in-walls? I mean, maybe my expectations were low but these turned out great. So screw it. They get five stars. Would love to hear from someone who knows something about in-walls and tell me their thoughts.
