Lifetime Tech Support

OSD Audio IW540 in-wall speakers are the most popular in the 5.25" category. This compact speaker pair deliver outstanding sound quality and include a higher power rating, a silk dome tweeter and an advanced crossover network. The pivoting tweeter lets you tailor the direction of the sound while the crossover ensures smooth low frequency, clear mid range and crisp highs.

Why choose in-wall speakers over regular speakers?
Typically rectangular in shape (although we do offer square models), 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 decor. 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.

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.

7 Questions asked on 5.25" In-Wall 100W Speaker Pair w/ Carbon Fiber Woofer & Pivoting Tweeter - IW540

richard • 12/17/2019, 2:17:43 PM Q i'm going to install these in my ceiling and wanted to know if there is a housing or cover for the back side to keep insulation off the electronics?
Customer Service • 12/17/2019, 2:17:43 PM
A Hi Richard: We get this question all the time. If it is rolled insulation with a mylar foil backing then you would not need anything. I the case of blown in loose insualtion you will need something to isolate the back of the speaker from the insualtion. We are currently developing a solution to this but in the interium we do recommend an affordable product that works very well. Checkout the following link... I hope that helps, thank you for considering OSD branded products. TL
Ben • 12/17/2019, 2:17:43 PM Q I have an existing 9 5⁄8 x 17 7⁄8 cutout in my wall and need to find replacement speakers. This model has the same size woofer but is very different in cutout dimensions. Which speaker could I buy to match that cutout?
Customer Service • 12/17/2019, 2:17:43 PM
A Hi Ben: What is you application, background music, critical listening or the right and left speaker of a LCR Home Theater? Do you have room to make your cutout bigger? if so why not step up to a 6.5" two way or even 8". We could not read your dimensions, please send them again and let us know what is your actual application. THX TL
Ben • 12/17/2019, 2:17:43 PM Q My cutout is nine and five-eigths by seventeen and seven-eigths inches. The cut out could be significantly taller but not much wider than nine and five-eighths, maybe an inch on either side. The speakers are the left and right in a 5.1 setup.
Customer Service • 12/17/2019, 2:17:43 PM
A Hi Ben: If your cutouts are that large it sounds like you were using three identical speakers, Dual 5.25" (or maybe 6.5") for the LCR speakers with the left and right mounted Vertically and the center mounted Horizontially. The rule of thumb is that the three speakers featured for the front stage need to be properly timbre matched. They all need to be of the same series with identical cone material. Tweeters usually need be the same size and materal as well, a 1 inch silk soft dome as an example. All our Dual 5.25" speakers are based upon being able to mount Horizontially between two studs. The vertical mounting is not as much of a challenge. Your measurements point to a larger speaker that may match your center channel that I am assuming had be customized between three studs. We can offer a number of options if you are able to work with a smaller hole size. Thank you for the clarification, I hope we can help you further. TL
Matt • 12/17/2019, 2:17:43 PM Q I just want to connect an mp3 player to these in just one room. Do these speakers have an auxilary cable that would allow me to do this?
Customer Service • 12/17/2019, 2:17:43 PM
A Hi Matt, No, you would need an amplifier like our AMP120 to power these speakers properly. Your MP3 player would connect to the amplifier using a 3.5mm mini RCA to dual standard RCA adapter cable. This cable is plugged into the headphone jack of the MP3 player with the 3.5mm connector. You then plug the two RCAs into the AMP120. Keep in mind you'll need CL3-rated speaker cable to connect to the speakers and figure out a away to get the speaker wire inside the wall to connect to the back of the IW540. TL
Mark M • 12/17/2019, 2:17:43 PM Q I need speakers for an indoor hot tub room. Would these be OK in a humid environment?
Customer Service • 12/17/2019, 2:17:43 PM
A HI Mark: The IW540 are not weatherproof. Your best choice would either be the ICE600WRS or ICE800WRS for your application. These are for in-ceiling application versus in-wall but are weatherproof. You also have a choice of a single stereo speaker like the ICE600TTWRS or the eight inch version ICE800TTWRS. Your other weatherproof option would include any of our AP series indoor outdoor patio speakers like our AP520 (white or black). TL-2112
