    The OSD IW525 in-wall LCR (left, right, center) trimless speaker is an economical and space-saving option for adding left, center and right channels to a home theater or media room. With its architect trimless design this in-wall LCR speaker can be used as a center-channel speaker in a surround-sound stereo or as a right or left speaker in a high-end system and complete your design looks. Dual polypropylene woofers produce clear, full bass tones with smooth high-frequency roll-off, while the 1" silk dome tweeter gives you distortion-free sound on the high end. The IW525 is capable of handling up to 150 watts so it can be paired with robust sound systems, and it's easy to install with the included template.

    Why Go Trimless?
    It's really a matter of aesthetic preference. These flush mounted speakers are hardly noticeable; that is until they're playing. Our trimless speakers do not include the 3/4-inch trim you typically see around in-wall speakers. The micro flange grilles are attached by extremely powerful magnets that stay put for quick and easy installation. Adds less visual impact on your architectural audio installation.

    Why choose in-wall speakers over regular speakers?
    Typically, rectangular in shape in-wall speakers are mounted in the wall and take up far less space than traditional box speakers. Customers love that wires are neatly concealed behind the wall and OSD in-walls can even be painted to match a room décor. Most in-wall speakers use the wall cavity as their enclosure or cabinet, which explains why in-wall must be installed to sound right. In-wall speakers come with special screws (called dog ears) that flip out and secure to the drywall (or other wall surfaces), a nearby stud, or a special frame attached to the studs. Custom installation frames (brackets) can also be purchased for a more secure fit or for lighter wall materials that require more support. In wall speakers are often categorized by the size of the woofer, not the size of the speaker itself.

    What Type of Speaker Wire and What Gauge?
    Wiring is not included with in-wall 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.

    Installation Tips: For optimal sound, separate speakers by six to ten feet. Carefully plan the layout of your home theater system, as speaker installation requires that you cut a hole in your wall.

    For a retrofit installation, no construction bracket is needed.

    Anthony • 12/17/2019, 2:17:43 PM Is there a bracket that fits this speaker for pre-construction?
    Customer Service • 12/17/2019, 2:17:43 PM
    Hi Anthony, At this time we do not offer a bracket for this center channel. This speaker includes dog-eared clasps that secure the trim to the drywall. Therefore, a bracket is not required. CL/MA 1356
    Willie • 12/17/2019, 2:17:43 PM Can this speaker be installed on a sloped (cathedral ceiling)? I am trying to determine what speaker to use as my center speaker, this speaker will be over the TV, with the couch on the opposite wall. Thanks for the help.
    Customer Service • 12/17/2019, 2:17:43 PM
    Hi Willie, The OSD IW525 center channel can be used for your application. If you havent selected your front left and right speakers, we suggest our the ICE630 angled speaker which gives you 15 degrees on its own with the angled frame of the speaker; plus the pivoting tweeter angles 15 degrees. This way you can direct the sound directly at your listening area. CL/MA 1478
    Dwayne • 12/17/2019, 2:17:43 PM I have an opening of 5 inches in height, length and death is not an issue. Will the speakers them selves fit in that opening. I have no way and cannot cut it out more than 5.
    Customer Service • 12/17/2019, 2:17:43 PM
    Hi Dwayne, The cut-out diameter on the IW525 in-wall center channel speaker is 15-1/4" x 6 7/8" with a mounting depth of 3 1/2". Therefore, this model speaker will not be a good fit for your application. As an alternative, we suggest installing three angled speakers for your center, left and right in the ceiling for your front stage. Take a look at the ICE630 angled ceiling speaker in the same series. We also have a lot of helpful information in our home theater learning section: CL/MA 1636
    Deborah • 12/17/2019, 2:17:43 PM I have plaster walls - cutout is no problem, but the wall is 2" thick. would this work? Thanks.
    Customer Service • 12/17/2019, 2:17:43 PM
    Hi Deborah, The dog-ear clamps on this in-wall speaker have a 1?-inch clearance. You could take the time to notch out the plaster where the six ears need to swing out and tighten. You could also remove the dog-ear post and screw the speaker directly into the plaster. Either way, it would take considerable time to modify the wall or the frame. Modifying the frame would void the warranty and possibility of returning the unit as well. TL/MA #1688
    Chris • 12/17/2019, 2:17:43 PM Hi, any idea if these will be available soon?
    Customer Service • 12/17/2019, 2:17:43 PM
    Hi Chris, The IW525 is discontinued and we will not be selling them any longer. We will be continuing with the IW545 however, and those should be back in-stock within the next couple of weeks.
