Features & Specifications

A step up from our most popular ACE640 in-ceiling speaker, the ACE645 ceiling speakers combine elegant, modern style with outstanding audio performance. With power handling up to 150W, features include a 6 1/2" mica-filled polypropylene cone and butyl rubber surround, and 1" silk dome tweeter. The micro-flange grilles have a super thin trim (0.15"), giving the ACE speakers a clean and sleek appearance that seamlessly integrates into any design space. Contour switches let you tailor frequency response to your room arrangement, and these in-ceiling are so discreet you can even match your recessed lighting.

What kind of speaker cable is needed?
Wiring requirements will depend on your local building codes; however, OSD Audio offers CL3/FT4 cable that is UL (fire) rated for all residential and most commercial in-wall and in-ceiling applications. (The exception is you cannot run this cable in heating or cooling ducts in commercial applications.) This cable includes a heavy-duty outer jacket approved for in-wall/in-ceiling installation. The high quality plastic jacket is also very flexible so it's easy to run the wires inside the wall.

Can I Test My In-ceiling Speakers before I Install Them?
Sure, many customers like to test the sound quality before they install them. Keep in mind, however, that these flush-mount speakers are designed to be used in the wall or ceiling. Uninstalled in-wall/in-ceiling speakers will sound weak and tinny because without the proper enclosure (in this case your house wall) the speaker can’t produce the sound pressure level it needs. If you want to try them out, we recommend mounting the in-ceiling speakers into a box of about 3 cubic ft. or larger; or simply mount them in the ceiling and then listen. This will give you an accurate measure of the sound quality.

Note: For a retrofit installation, no construction bracket is needed.

do i need speakers brackets for the new constraction?
1 Answer
Hi Kamran, The new construction brackets are optional. They help during the new construction phase with product placement and provide a little extra stability once the slat wall or ceiling tile has been installed. All of our OSD branded in-wall and in-ceiling speakers utilize a dog-ear mounting system that will work without using the new construction bracket. That way we only stock one speaker that will work for both new construction or retrofit.

do I need rough in mountings for these speakers?Also, do you have a recomendation for rooms with just one speaker? both channels in one.

David, The ICE640TT is the ideal single stereo speaker. It has dual voice coils to connect a stereo signal (right and left). It also features dual tweeters for broader dispersion of the high frequencies. Another bonus is the 8/16-ohm impedance switch. When using the ICE640TT (or ICE840TT, 8" version) as single summed stereo mono speaker, you set the impedance switch to 16 ohm. You can also connect two of the ICE640TT as a stereo pair making sure to set the impedance switch to 8 ohm. You then connect the right input on one speaker and the left input on the second speaker. The advantage is the dual tweeters that give you the larger listening area with the broader dispersion of the higher frequencies. TL

David, Our speakers feature dog eared clasps that tighten to the dry wall in a retro-fit design. No bracket is necessary. Regarding a single stereo speaker I would recommend for you the ICE640TT. CL

How far apart should your 6" and 8" speakers be?
1 Answer
Hi Steve, It depends on whether you are listening to these speakers for true stereo separation where you will be sitting in the same location or if they are just for background music. For critical listening we would recommend 6 to 8 feet apart (for both the 6 and 8 inch which have the same tweeter) with the tweeters pivoted at your listening area. Otherwise figure 8 to10 feet apart and you just need to make sure each speaker is at least 3 feet away from the nearest wall. TL/MA

when you order a one pair does that mean your getting 2 speakers or does pair mean the trim and speaker together?
1 Answer
A pair means you’re getting two completer speakers, one for right and one for left stereo output. They are complete with everything you need to install other than speaker wire which we sell separately. The speaker wire needs to be CL3 rated approved for in-wall/in-ceiling application. If you’re running a length of under 80 feet, 16 gauge will work fine. Over 80 feet, we recommend 14 guage, both which are available from OSD. TL/MA

Hi this is my first time on this site and this is a grate items. I'm finishing my basement in my new home that we build last year and now I need some speakers, my question is do I need to buy brakets for speakers or I can just put them in driwall? i will need 3 pairs for my basement
1 Answer
Using a new construction bracket helps in both the alignment of the speaker while providing additional support. You will notice the ACE 645 audiophile in-ceiling speaker has a substantial crossover which makes it heavier than your standard in-ceiling speaker. We typically recommend the use of the brackets when you have access to the bare jousts. Model NCCB6 is the recommended Bracket for the ACE645 speaker.
