## Description

ACE (Architectural Ceiling Element) Series ceiling speakers combine elegant, modern style with outstanding audio performance. The stealthy micro flange grilles have a thin (0.15-Inch) trim, giving the ACE speakers a clean and sleek appearance that seamlessly integrates into any design space. Step-up features include contour switches that allow you to tailor the bass and treble as well as a pivoting silk dome tweeters. The ACE Series may be well hidden but the outstanding sound quality will be very obvious.

Review: I ordered the speaker to replace a clients speaker that had failed (different brand). This speaker was the same size, however I had to cut the hole slightly larger to fit the new speaker. Other than having to adjust the hole size, it was an easy install. The sound quality is decent - it's basically what I expected at this price point. I've owned in-wall Definitive Technologies speakers which are absolutely amazing. If you just need a decent speaker to listen to music at a moderate volume, these are great. If you want something that can handle lots of power, and sound amazing - look into DefTech
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!

## Features

- TRIMLESS DESIGN: The ACE640 In-Ceiling Speaker Pair combine elegant, modern style with outstanding audio performance. With a very thin trim line, about .15”, you won’t even notice there are speakers there until you hear them.

- WOOFER & TWEETER: Featuring a 6.5” fiberglass cone woofer and a 1” titanium dome pivoting tweeter that directs the sound to wherever you wish, these speakers are perfect for any home audio setup.
- SOUND QUALITY: When mounted to a wall or ceiling, this speaker pair solves your audio placement problems and creates a more realistic sound image when compared to other in-ceiling speakers.
