## Overview

The OSD Audio ACE870 is a trimless 8-inch in-ceiling speaker designed for high-performance home theaters and commercial spaces. With 175W power handling, a 15° angled mid-bass driver optimized for Dolby Atmos setups, and front-mounted contour switches, it offers customizable, immersive sound. Its Kevlar woofer and robust magnet structure ensure deep bass and clear highs, while easy installation hardware makes it a seamless upgrade for any surround sound system.

## Description

The ACE870 Atmos Ready LCR In-Ceiling Speaker sounds great , looks great and is powerful enough to fill larger home theaters or commercial spaces with rich, enveloping sound. Designed with high-end components and audiophile features, the ACE870 can handle up to 175 Watts of power so you can push volume levels without stress or vibration. The mid-bass driver is angled at 15 degrees, which gives you more placement flexibility than standard in-ceiling speakers. This makes the ACE870 ideal for a Dolby Atmos down-firing speaker setup where the overhead sound is an essential part of the 3D experience. An angled speaker can be installed closer to the wall, just above the screen, and the speaker assembly can be aimed at the listening area. In addition to crisp, detailed mid and high frequencies, this single speaker kicks out impressive bass due do the 8"" Kevlar woofer and heavy-duty and efficient magnet structure that focuses energy within the voice coil gap. Other features designed into the ACE870 include front-mounted contour switches, so you can tailor bass and treble to your preferences as well as butyl rubber surround that gives the speaker more excursion capability for deeper bass and wider frequency response. Installs into ceilings with four easy-to-lock-in dog-eared brackets and includes a cut-out template.

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!

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.
