    Lifetime Tech Support

    One of our most popular in-ceiling speakers (just look at the reviews), customers often install our ICE640s in 5.1 or 7.1 home theater rooms, although these speakers are also great for whole house audio. With excellent power handling capability (150W), the ICE640's can produce very smooth bass notes, an even soundstage and realistic sound resolution even at high volumes. Features include a 6'" cone with butyl rubber surround, a 1" titanium pivoting tweeter, and an advanced crossover network for clear dialog. Built from the ground up, OSD products offer the most thought out, totally dialed in sound while providing year after year of sonic excellence!

    Pivoting Titanium Dome Tweeter
    The job of the tweeter is to deliver the higher frequencies of music and soundtracks. The tweeter is also adjustable, meaning it can be aimed toward the listening area. This can make a big difference in sound quality especially for dialog and higher frequencies.

    How Does this Speaker Mount in the Ceiling?
    Customers often ask us if they need special installation mounting brackets on their OSD ceiling speakers. The answer is no and here’s why. All our in-ceiling speakers feature a dog leg (L-shaped) mounting system that is part of the frame. Before you install the speakers, remove the grille and you’ll see several the mounting screws near the front frame. These screws need to be loosened to activate the dog leg clamps. Use a screwdriver to loosen (turn to the left) these screws and the clamp will come loose. When the speaker is in position in the ceiling, tighten (turn to the right) the screw and the speaker will be secured to the ceiling.

    What Type of Speaker Wire and What Gauge?
    Wiring is not included with in-ceiling speakers so you will have to purchase some. We recommend our OSD Audio CL3/FT4 cable that is UL (fire) rated for in-wall and outdoor speaker installs. This type of 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. As for the gauge, for runs up to 100 feet for background music, 16-gauge will be fine. If the run is approaching or exceeding 100 feet, we suggest 14-gauge wire. 

    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.

    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.

    Chad • 12/17/2019, 2:17:43 PM How do I get the speaker grill off?
    Customer Service • 12/17/2019, 2:17:43 PM
    Hi Chad: One way is to hold the speaker with a hand on oposite sides of the frame. You will find the frame before it is insatlled flexible enough to work the grill out by twisting your hands back and forth opposite of each other slowly working the grill out. Another way is turning the speaker over and releasing two of the dog ear clips and slowly pushing the grill out with the head of the screws. Option one is better because there is less chance of denting the grill. Good luck...
    Robert • 12/17/2019, 2:17:43 PM Will the 9.5 diameter of this speaker and the ICE 650 fit in the 6.5 BB6 speaker box. The largest listed speaker diameter that you have listed is 9.25. Wondering if tolerance in the BB6 is so tight that an extra .25 inches will not fit.
    Customer Service • 12/17/2019, 2:17:43 PM
    Hi Robert, You are correct. The BB6 is not designed to work with the ICE640 in-ceiling speaker. These speakers do not require back boxes but some customers build their own. CL/MA 1366
    ANDY • 12/17/2019, 2:17:43 PM I want to add 4 of these speakers (ICE640) in a den ceiling as the main home theater speakers. I have a floor sub woofer I can use with these as well. Can my existing receiver (rated 4x100 watts)sufficiently power these speakers to create an above average sounding home theater experience? I am guessing that you CAN'T use a simple Blue Ray $150 home theater receiver with these speakers, if you disconnect the speakers provided in the set and replace with these ICE640'S?
    Customer Service • 12/17/2019, 2:17:43 PM
    Hi Andy, The ICE640 are our best polypropylene speaker and are commonly used in home theater. Your standard 100W receiver will drive these speakers; however, we recommend a surround sound receiver to experience the full enjoyment of the 5.1 or 7.1 audio soundtracks. We carry the Yamaha the RX-V373: http://www.outdoorspeakerdepot.com/home-theater-receiver-yamaha-rx-v373.html If youre doing all in-ceiling arrangement, consider using three angled matching speakers such as the ICE660 for your Front Stage (center, left and right). This will maximize the audio quality and give you the ultimate home theater experience. CL/MA 1373
    John • 12/17/2019, 2:17:43 PM I know they say the only stupid question is a question not asked !!!!!. If it doesnt come right out of the box with a simple plug it is I may be as rookie as thye get. I am also 62 and today is Veterans Day so be kind ...I am considering replacing my surround sound speakers with in the ICE640 High-end 6.5 ceiling speakers. I currently have a Sony surround system and here is what I can tell you straight from the manual. The power output and total harmonic distribution is: 6 ohm loads, both channels driven, from 120 - 20,000 Hz, rated 85 watts per channel minimum RMS power with than 0.7 total harmonic distortion from 250 milliwates to rated output. The amp section: 6 ohms, 1 khz, THD 10%..2 front speakers are 133/wch...center is 133 w....surround speakers are 133W/ch. Is it going to be as easy as replacing the current speakers with the new ceiling or will I need to purchase a different amp. Thank you in advance....John
    Customer Service • 12/17/2019, 2:17:43 PM
    Hi John, An amp rated at 6 ohms is not a good fit for speakers rated at 8 ohms. These speakers would work best with an 8-ohm home theater receiver like the Yamaha the Rx-v373. http://www.outdoorspeakerdepot.com/home-theater-receiver-yamaha-rx-v373.html The ICE640s are our best polypropylene speakers and are commonly used in home theater. Consider installing three angled speakers for your front, left, and right with the matching ICE660. We would also recommend a pair of the ICE640s for the rear channels. CL/MA 1374
    Stef • 12/17/2019, 2:17:43 PM Hi I am planning on hooking these speakers up to a SONOS system, at 55 wats per channel. These speakers are rated at 150 watts per channel. Will they still work or is there not enough power to power them?
    Customer Service • 12/17/2019, 2:17:43 PM
    Hi Stef, The second specification you want to look at is sensitivity. The ICE640 is rated at 91dB. The higher the number, the more efficient the speaker and the less power you need to drive the speaker. This will work perfectly with your SONOS Connect Amp. TL/MA - 1470
