    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.

    What's on your mind?

    Jon • 12/17/2019, 2:17:43 PM I was interested in these for my 5.1 surround however I have my center channel in the wall under my wall mount tv. Do you have a wall mount that would pair with the ceiling ones...Since the center is the most important?
    Customer Service • 12/17/2019, 2:17:43 PM
    Hi Jon, A couple of choices can match with the ICE640 series speakers. The first would be to utilize two of our IW545 LCR speakers that feature dual 5.25" mid-woofers and a 1" soft dome tweeter, which is the same woofer and tweeter material featured in the ICE640 speakers. Simply mount them horizontally with one woofer above the other. The second, more affordable, choice would be to use IW680, which shares similar cone materials and tweeter design as the ICE640. The IW545LCR is priced as each, and the IW680s are priced as a pair. If you have your heart set on in-ceiling speakers, we recommend using the ICE660 Angled LCR speaker, which was created for Front Stage Left Center and Right speakers. The angled woofer/tweeter allows the speakers to be mounted closer to the wall where the monitor is mounted, so it will work better with your center channel speaker. The ICE640 would have to be mounted almost directly overhead from your optimum viewing/listening area. This would create a weird disconnect with the center channel speaker. Be sure to check out our learning section for some excellent information on front stage speaker placement: TL/MA #1505
    Chad • 12/17/2019, 2:17:43 PM Just to be clear this comes with 2 speakers - as in a pair correct?
    Customer Service • 12/17/2019, 2:17:43 PM
    HI Chad: Notice on product page it says sold in pairs with two separate speakers coming in one box. TL - 1602
    Pawel • 12/17/2019, 2:17:43 PM I'm looking at getting 4 pairs of these 3 pairs for inside and one for outside! These can be used as outdoor speakers correct? I'm also looking for the correct receiver for this set up that has 2 zone feature,USB port and blue tooth capabilities. I will also need 4 volume controls that would work best for this set up. Thanks in advance
    Customer Service • 12/17/2019, 2:17:43 PM
    Hi Pawel, The ICE640s are excellent ceiling speakers but they are not designed for outdoor use. Another option is our ICE600WRS Weather Resistant 61/2" ceiling speakers. These are designed specifically to handle the outdoor environment. As for receivers, check out the Yamaha RX-V673 which features 2nd room output, USB input and networking capability with a unique control app for your smartphone, iPad or android device. It also features 7.2 with two subwoofer outputs. TL/MA 1664
    Pawel • 12/17/2019, 2:17:43 PM To add to my previous question I will have 5 pairs and will need 5 volume controls and the reciever will also need HDMI connection Thanks
    Customer Service • 12/17/2019, 2:17:43 PM
    Hi Pawel, Think about adding an external amplifier like our OSD AMP-200 with a DSM6 speaker selector and SVC300 impedance-matching volume controls. The Yamaha RX-V673 AVR we recommended has multiple HDMI inputs (4 inputs and 1 output featuring ARC, Audio Return Channel). TL/MA 1665
    Al • 12/17/2019, 2:17:43 PM Are the grills paint able?
    Customer Service • 12/17/2019, 2:17:43 PM
    Hello Al, Yes, you can paint the grills, but you should consult a paint specialist for proper instructions. Thanks! -BM
