Features & Specifications

On sale while supplies last. This moderately priced but sturdy single speaker is perfect for home theaters and whole house audio. Enjoy totally dialed in sound with an 8" polypropylene cone with butyl rubber surround. Two pivoting 3/4" silk dome tweeters serve up crisp high notes and dual 16-ohm voice coils can be switched for 16-ohm stereo operation or 8 ohm mono bridged setup.

What Is a Dual Voice Coil Ceiling Speaker?
A Dual Voice Coil (DVC) Ceiling Speaker uses a special voice coil cone design that allows both channels of a stereo system to drive one cone. Sounds complicated but it's not. Basically, a DVC speaker plays both right and left channels through one speaker cone. You get both channels but without the acoustic separation that happens with two speakers. There are places like bathrooms, closets or hallways that just can’t accommodate multiple speakers so a DVC speaker solves the problem and produces great sound.

Is an 8-inch In-Ceiling the Right Size for You?
For rooms larger than 140 square feet, an 8" in-ceiling speaker is an excellent choice. The 8” cone delivers excellent frequency response (the range of musical tones a speaker can produce); plus, bass response or the ability of a speaker to crank out those low notes is vastly better than small cone sizes. An 8-inch speaker can be used in home theaters and distributed audio, which is where an 8-inch cone shines. After all, whole house audio systems don't have the benefits of a separate subwoofer like home theaters so the added bass really makes a difference in audio quality.

Testing the Sound Quality of In-ceiling Speakers
Many customers like to test the sound quality of their new OSD Audio in-ceiling speakers 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. For a retrofit installation, no construction bracket is needed.

Can they be installed in the ceiling with insulated attic above? Is blown in insulation allowed to over the speaker safely?
1 Answer
Hi Dan: There is an excellent product that you can buy from AMAZON that will cover the back of the speaker for applications just like yours. See: OEM Systems ISF-147 Ceiling Speaker Protective Cover. I recommend these covers all the time. They are available from a multiple of outlets on line, the manufacturer is OEM. TL/3724

What is the variation of the frequency response spec for these speakers? +/- db?
1 Answer
Hi Prasad: Typical industry Standard +/- 3 dB 12dB slope on the crossover and some unique crossover to handle the Dual application switch 8/16 ohm. This allows the speaker to be used as a single stereo summed mono speaker where you connect both voice coils and set the switch to 16 ohms. This is for application where you have a stereo signal (right and left +/-) coming into a small room where you have only enough room for a single speaker. Bathrooms, hallways or master bedroom closet as an example. Most companies stop there with their DVC design. We add the switch and componentry so you can add a second ICE840TT and make it a stereo pair with dual Tweeters. Now you connect only one of the voice coils of each speaker and set the switch to 8 ohm. TL/3131

Looking at the PDF owners manual is the right channel supposed to be at reversed polarity coming from the amplifier?
1 Answer
HI Robert: Good catch, the diagram is incorrect, see the paragraph below stating Polarity must match. Note the speaker inputs are labeled + or - no reference to right or left. We will look into correcting the on-line owner's manual. TL/4190

I have one of these in my kitchen and love it. Now I want to use two of these outside along my deck, spaced far apart, under the eaves (4-6 feet deep). Having two stereo speakers works better because some music has a lot of stereo separation which bounces back and forth along the deck (and you can miss half the song). They won't get directly wet at all in their planned location, but obviously there will be high humidity at times (live in Seattle). Would you recommend using this outside in my circumstances?
1 Answer
Hi Mark: An excellent choice for both your kitchen as well as your outdoor application. These speakers also feature a dual application switch which allows you to connect just a single voice coil and run two of them as a stereo pair with dual tweeters both working giving you a wider dispersion pattern. Then place 6 to 8 feet apart and still give you excellent stereo separation. The connection would be the same with two stereo signals coming out to the porch. The only other thing I would suggest is to use a little weatherproof silicone around the inside of the frame around the cut out hole. You could go with your original idea and see if its enough coverage and still have the option of adding two more down the road and just change change the switch from 16 ohm to 8 ohm and just wire up a single voice coil on each. Please let us know if you need further clarification. (see the diagram included with the images of the IC840TT on our site. TL/3210

Do you need a bracket to install the speakers?
1 Answer
Leslie, The ICE840TT like all of our inceiling speakers have dog eared clasps that make for a retro fit design, so no bracket is needed. CL

can i paint these speakers and if so should i remove the material glued on the grill before i paint?
1 Answer
HI Rich: Yes these speakers are paintable and you do need to remove the cloth inside the grill before you paint. The cloth is morer for cosmetic effect so there is no need to replace it. TL

Hi, I have a ceiling bracket for a different speaker currently in my ceiling that I can't change. It's diameter is exactly 10", but I want to install this speaker in that whole. Will this speaker properly mount into a diameter cutout of 10" or is the whole too big? Thanks
1 Answer
Hi David: The cutout of this speaker is 9 5/16". The diameter of these speakers is 10 5/8". The flange is 5/8". It will work but there will not be a whole lot of the flange that will contact with the ceiling. TL

November 21, 2011
I bought the ICE840TT High Definition Pro Stereo 8" Ceiling Speaker and hooked up both the right and left channels using to two speaker cables (black/red). I have a Sony STR - DE715 receiver, the speaker sound great for a while and then my receiver blew a fuse. I have a feeling that I should have set the Ohm switch on the back of the speaker to 16? .....I think I left it 8 Ohm. I am hoping that the only damage done is the blown fuze? Can you give me some insight on what I should have for settings, as far as the speaker/receiver? Thanks Darren
1 Answer
When connecting both voice coils, the speaker should be set to 16 Ohms. With both wired in parallel, you divide the impedance by 2, equaling 8 Ohm which is what the typical A/V receiver likes to see. When in the 8 Ohm setting with both voice coils connected, the receiver sees a nominal 4 Ohm load. Music can be very dynamic and the impedance changes constantly lower and higher. When it goes even lower than the 4 ohm for an extended period, the receiver will have issues (like blowing fuses).The 8 Ohm setting is when you use two of these speakers and only connect one voice coil per speaker, wiring two of the speakers as a stereo pair. The advantage to this setup is the dispersion pattern of the dual tweeter that provides a wider sound. TL/MA

Excellent quality and sound
Easy to install, sounded great when installed in drop-ceiling tiles, dual-cone design worked perfectly with 30-watt in-wall stereo amp for small office setup. Client was so happy they immediately ordered two more for another office.
ProsEasy hookups, nice template for cutting holes, switch for 8-ohm or 16-ohm resistance.
ConsGrill is a little tough to pop out for accessing the dog-ear screws and instructions weren't clear how to do it. Use the little hook tool around the edges and gently tug on it with a pair of pliers and you'll eventually work it out. Once installed, the grill goes back in firmly and definitely won't fall out.
Best UsesBlends stereo output into a single speaker very nicely. Sound quality on a 30-watt amp was excellent.

EXCELLENT speaker, I am using this ICE840TT (#2) as my TOP MIDDLE SPEAKERS (three foot forward centered over listening couch) in my 5.32 system, the 3 is a 12 inch Pioneer TSW311D-4 Champion (right channel front Sub), and a 8 inch Polk Audio DB840-DVC (left channel front Sub) pared with a 12 inch Rockville W12K6D-2 (left channel rear Sub) running on a Radio Shack MPA250 PA Amplifier. The front (left and right channel) speakers are custom built (in wall) 10 inch Technics woofers, 8 inch Rockville RXM88 PRO mid ranges, and Rockville RT4 2 inch Titanium Tweeters running custom cross overs. The Center channel is running a Rockville RM88 PRO 8 inch bass - mid bass, a PYLE-PRO PDMR-5 5 inch mid range, and a Pyle PDBT28 1 inch Tweeter with custom crossovers, in a ported box behind the Emerson 55 LCD LED TV. Bringing up the left and right Rear Surround Channels are Custom in wall 8 inch Rockville RM88 PRO bass - mid bass and a Rockville RT4 2 inch Titanium tweeters. The DENON AVRS710 Custom Calibrated EQ, Running the ATMOS DTS:X This ICE840TT sounds BEAUTIFULL clean sweet bass and tweeters..... IT ROCKS..... Would be perfect for a 7.1 Rear (right and left) centered Speaker also.

Used this speaker (dual voice coils) for a replacement in a kitchen ceiling where the former owner only had a single speaker however there was wiring for both channels. This speaker required me to enlarge the cut-out by about 3/4' all the way around. The cut out template that came in the package was perfect. Simple masking tape to ceiling, trace, remove and sheetrock/drywall hand saw - done in 2 minutes. Quick install, 15 minutes start to finish & the sound is fantastic for a single speaker. Remember to flip the switch to 16 ohms....OSD Thanks for a great improvement!
Proscut out template, no bracket required, sandwich clamps worked great

I have one of these installed in my bathroom and I am amazed on how great it sounds. All the rest of my equipment is Klipsch, and this speaker sounds just as good! but for only a fraction of the price of the Klipsch speaker. Shipment was fast too! I would buy from here again!!!

Speaker is very easy to install (even for the technically inept like myself), looks great, and sounds much better than my expectations for a speaker in this price range. Just be mindful of correct wire polarities, but otherwise this was a virtually effortless project to install in my bathroom ceiling.
