Features & Specifications

On sale while supplies last. A very popular single speaker for home theaters and whole house audio, ICE640TT in-ceiling speaker includes a 6 1/2" polypropylene woofer with butyl rubber surround, dual 3/4" silk dome tweeters for smooth vocals, and 150W power handling. This single in-ceiling speaker uses dual 16 ohm voice coils and includes a switch for 16 ohm stereo operation or 8 ohm mono bridged setup.

Why Dual Voice Coils?
 The beauty of the DVC design is that it allows you to connect both a left and right stereo signal. This makes it an excellent choice for locations with room for only a single speaker (i.e., bathrooms, narrow hallways or even a walk-in closet). Once both voice coils are connected, the stereo signal is summed into a single mono stereo full range output. In addition, dual tweeters doubles the dispersion pattern of the high frequencies, creating a broader 360-degree sound field. Add this to the overall sound quality of the Kevlar Woofer and you have one heck of a great sounding speaker!

What Is Butyl Rubber Surround?
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 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.

Do I need special cable for in-ceiling speakers?
Wiring is not included with in-ceiling speakers so you will have to purchase some. While wiring requirements will depend on your local building codes, 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.




For a retrofit installation, no construction bracket is needed.

Dan
from CT asked:
December 5, 2012
It says that this is a 16 ohm speaker? Not electronically gifted, but the rest of my speakers are 8 ohms (normal) and I have them and will have this one going through individual volume controls. The vol controls are set based on how many pairs of 8 ohm speakers are in service. Is this speaker equivalent to a pair of 8 ohm speakers?
1 Answer
Hi Dan, You are correct in thinking it is equivalent to a pair of 8ohm speakers. The speaker features a 8/16 ohm switch so in the 16 ohm setting you connect both voice coils of the single speaker and it sums the stereo signal into a full range mono output. This is for an applications where there is only room for a single speaker but you have a left and right stereo signal coming into the room. The dual tweeters provide a wider output of the high frequencies below the speaker. Now unlike most manufacturers who also feature a Dual Voice Coil speaker for this single stereo speaker application our ICE640TT and ICE840TT feature the 8/16 ohm switch which allows you to add a second speaker where you connect only one of the Dual Voice Coils to each. Then set the switch to the 8 ohm setting so you now have a stereo pair of these speakers (one for left and the other for the right channel). The key to this is the dual tweeters both operate in either the 16 or 8 ohm setting. So now you have a wider dispersion pattern for the stereo pair. Four tweeters are better than two. I hope that helps. CL/TL - 1440

Can a speaker like this...single woofer dual tweeter be wired for center channel use in a 5.1 system?
1 Answer
Hi Mike: Yes the ICE640 with its dual application 8/16 ohm switch will allow you to connect it as a single input speaker. Just set the switch to 8 ohm and connect the two conductor speaker cable (+/-) to either one of the two available inputs. In fact you could wire three of these speakers the same way giving you an LCR setup, (Left, Center and Right Front stage). The switch also allows you to wire these as a stereo pair in the 8 ohm setting. You would set the switch to 16 ohm if you were using this speaker in its typical application as single summed Mono/Stereo speaker. Application include locations where there is only room for a single speaker but have four conductor stereo wire (right and left, +/-) coming in to the room. So you connect both of the inputs (one for left and the other for right channel). In both settings 8 or 16 ohm both tweeters are active. I would be curious to hear about your actual setup, Receiver, 7.1 or 5.1 and what other speakers are you using for Front stage and your surround speakers. My email is tim@osdaudio.com. TL/3840

Can these be mounted in a bathroom where the moisture area is high? I noticed it doesn't say.
1 Answer
Hi Quincy: Yes you can mount them in a bathroom where moisture is higher than a normal room. We just suggest you use a little bead of silicone on the backside of the frame so you create a seal between the frame and cutout hole. That will help isolate the front of the speaker exposed to the bathroom from the back of the speaker located inside the ceiling. Good choice... TL/3782

from Los Angeles asked:

I've just built a house and had 640TTs installed across 8 zones, and now have to select the Amp configuration. There are 6 speakers in the great room ceiling, two in the dining room, and 5 on the upstairs deck. I assume I need a dedicated amp for the great room zone, trying to figure out how powerful it needs to be to drive them. Will be attached to Sonos or Nuvo zone controller.
2 Answers
Hi Mark, You will need an AMP300 for the grate room and you would want to run a speaker selector from the amp to allow 6 zones. See the ISS6 for example. Or, you could even just run an MX1260 which is a 6-zone amp.

HI Mark: Did you install all ICE640TT in all locations? Are all 6 speakers in the great room ceiling ICE640TT wired with both Voice coils (left & right) connected and the switch on the back set to 16 ohm? Do you have blueprint of the house or can you create a diagram to show us how you laid out and wired the system. I am very familiar with both NUVO and SONOS. I would also need to know what other components you are planning to using. Are you doing a Custom Home Theater as well. You can go to our Learning Center and see the Upload your Plans area. TL/3130

Mike S
from SLC, UT asked:
March 1, 2013
I have an amp that is rated for 4 ohms resistance at 220w per chanel. I have 2 ice640TT speakers one each for two small rooms. My question is can I install these in parallel with 16 ohms selected on the speaker. This would result in the over resistance being 4 ohms. I know the wattage is a little more than the speaker is rated for but there small rooms the volume will never be that loud. I am down to my last channel and need to drive the two rooms together.
1 Answer
HI Mike, In order to do this you will need a minimum two channel, right and left, positive and negative so you would connect both voice coils for each speaker. You could run a 4 conductor 16/4 to the first speaker and then run a second four conductor from the first speaker to the second speaker. Make sure the application switch is set to 16 ohms for both speakers. The two speakers run in parallel and would show a 4-ohm load to your amplifier. TL/MA 1670

Mathieu
from Montreal, Canada asked:
August 4, 2012
We bought a couple of ICE640 speakers for our A-BUS system. Now, we want to add other zones in smaller rooms using the ICE640TT stereo speaker. I am not an expert, and not sure I understand the 16 ohm vs 8 ohm setting since we want stereo sound but Russound A-BUS A-KP2 keypad states 8om speaker pair. Will it work ? (we are very satisfied with the ICE640 speakers!)
1 Answer
Hi Mathieu: The A-Bus system is usually restricted to a single pair of 8 ohm speakers. On a couple of the A-Bus component hubs they allow for second controller to be wired into a zone like a sub zone which has to share the same source but the volume levels can be controlled individually. I am thinking you could not connect two speakers in Parallel which might overload the A-Bus amp built into the Control Pad and connecting a second set of speakers in series would cut the output of the A-Bus in half (they are already considered under powered so cutting in half would not be advisable). But if you have the ability to add the sub zone with its own control pad (and built in amp) then you would just wire the ICE640TT with a four conductor connection from the Key pad (left and right +/-). The ICE640TT has a dual voice coil and dual tweeter. It has a application switch on the back as well which allows you to connect two of these as a stereo pair. You would set the application switch to 8 ohm and connect only one of the voice coils on each speaker. To connect as single stereo summed mono speaker you set the switch to 16 ohms and connect both voice coils. This ideal for areas/zones where there is only room for a single speaker. Like a Bathroom, Walk-in Closet or narrow Hallway. I hope that helps. Please let us know what you have for A-Bus components. TL

April 3, 2012
Can I use a different bracket for this speaker? The recommended one is out of stock.
1 Answer
Hi Jason, The speakers do not have another bracket. For a retrofit installation, no construction bracket is needed. You simply cut the drywall and the dog-eared clasps secure the speaker around the trim. If this is new construction and you prefer to have the bracket, it will be back in stock 5/31/12 CL/MA

James
from San Diego asked:
November 6, 2011
I'm interested in the ICE640TT for installation in my bathroom which will be connected to my receiver via a Zone B output. The receiver can output 100w max on zone B. I also want to control the volume using one of the rotary volume controls you guys sell. I haven't wired a system with a volume control before. Since this speaker can handle up to 150 watts (I'm assuming peak, not RMS?) does that mean the SVC100 will be sufficient? I guess I'm asking, do you match the volume control to the peak output of the receiver or to that of the speaker?
1 Answer
The SVC100 will work fine. The output of the amplifier/receiver is more important. TL/MA
