Features & Specifications

The ACE640 ceiling speaker is the trimless version of our most popular ICE640 ceiling speaker. The ACE640 is the best combination of sound and price, it delivers very smooth silk toned music sound with 6.5" decent bass.

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") bezel, giving the ACE speakers a clean and sleek appearance that seamlessly integrates into any design space. The ACE Series may be well hidden but the outstanding sound quality will be very obvious. Adds less visual impact on your architectural audio installation.


Other Product Info

What are the benefits of Butyl Rubber Surround?
Much more expensive with almost double the shelf life of foam, butyl rubber has been the choice of speaker designers looking to optimize the sound based upon materials that go together. The Surround is just one of the integral parts of the speaker's motor structure. Butyl rubber allows the use of unique cone materials like Kevlar and mineral-filled composites. Butyl Rubber gives the speaker more excursion capability featuring a deeper bass with a wider frequency response, and its shelf life is closer to 25 years compared to the foam at 12 to 15 years.

What Gauge Wire Should I Use for my In-ceiling Speakers?
For runs up to 100 feet for background music, 16-gauge will be fine. If the run is approaching or exceeding 100 feet, use 14-gauge wire. OSD Audio offers CL3/FT4 cable that is UL (fire) rated for all residential and most commercial in-wall and in-ceiling applications.

Paint the Grilles for a Custom Touch!
Many of our customers like to paint the grille of their in-ceiling speakers to match their room décor. Painting the grilles/trim won’t harm your speakers but be sure to use spray paint; never a brush. Brushing the grilles can clog the holes and interfere with sound quality. We also recommend using a fine spray paint gun, the inexpensive kind that you can pick up at your local hardware store. Our in-ceiling speakers also come with a paint shield to help guide you.

For a retrofit installation, no construction bracket is needed.

Please note: Use cut-out diameter according to the bullet point on the website.

Can this speaker be used as a center speaker?
1 Answer
Hi Efrain: It is hard to answer this question without knowing what you are planning for your left and right front stage speaker. Your front stage should have the proper timbre match which if possible all three speakers should have the same tweeter and share the same cone material and similar crossovers. Check out the angled in-ceiling speakers which were originally designed for Front stage LCR. The angled speaker allows you to mount the speaker in the ceiling closer to the adjacent wall where your TV/monitor would be mounted. The key is you need to have the tweeter of the speaker facing your optimum seating/viewing area. The Tweeters which outputs the high frequencies are very directional so it is important how they are aimed. A standard in-ceiling speaker (like both the ACE640 and ACE600) has to be placed almost directly overhead of your listening area in order to hear its full range. Note the tweeter of the standard frame, pivots or swivels 5% so you can place the speaker a little in front of your sitting area. But with the angled speaker you have a 15-degree angle plus the extra 5 degrees from the pivoting Tweeter allowing you to place the speaker closer to the TV so you can hear the sound like it is coming from the TV. So check out the ACE670 or even better look at the 8" version the ACE870 for all three of your front stage speakers. Which brings us back to the question "What are you using for your Right and left front speakers. Knowing that will help me look for the best match for your system. Please let me know, Good luck TL/5023

what kind of amp should i use with my ACE640 ceiling speaker
1 Answer
Hi Shawn: If you are looking for an amplifier for one or two pairs of these speakers check out the XMP100 (best value) or step up to the AMP200/300 for best sound and most power. Want more than 2 pair, then the AMP200, Speaker Selector and Volume Controls would work. TL/ 4795

Can I use these speakers as a wall speakers too.
1 Answer
Hi Mitch, You can install the ACE640 in-ceiling speakers in the wall as well. Choosing round- or rectangular-shaped speakers is a matter of personal preference. Our customers often install wall speakers in the ceiling and vice versa. CL/MA 1496

Are they easily mounted in drop ceiling
1 Answer
Hi Charlie, Yes, these are easy to mount in a drop-down ceiling. We would recommend removing the tile, cutting your hole, and mounting the speaker. Then connect the speaker wires as you re-install the tile. TL

dothe grillscome off to paint or dye ?
1 Answer
Our grilles are removable and paintable. We wouldn’t suggest dying the surface, however, as the surface of the grille would not absorb the dye well. MA
