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: 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.

Mac • 12/17/2019, 2:17:43 PM is this out of stock or discontinued? if out of stock when do you anticipate it being back in stock?
Customer Service • 12/17/2019, 2:17:43 PM
Hi Mac, This model was discontinued and replaced with the MK-IW550LCR
James • 12/17/2019, 2:17:43 PM I am considering buying this as my center channel, but my question is what speakers to purchase for L & R channel? Two others like this or just regular in-wall speakers. I have a Pioneer SC-81 receiver 7.2 and a 20'X15' family room (open concept floor plan). Main uses include home theater, some light gaming, and music to entertain guests inside and outside of the house.
Customer Service • 12/17/2019, 2:17:43 PM
Hi James, I believe this model is discontinued and replaced by our MK-IW550LCR. You would best match this lcr with the MKW-850 or MKW-650 as your front L/R.

Hi Douglas: This speaker is being discontinued with a two new speakers in its place one being a direct replacement; Dual 5.25" MTM (Mid-Tweeter-Mid) Trimless LCR and the second speaker a step up Dual 6.5" MTM Trim-less LCR speaker. They are due in this month (May). Stay tuned, we will update the page to announce the new replacements.
