Features & Specifications

Sold in pairs, the OSD-MK540 is popular in-ceiling speaker for whole house audio and home theater surround sound. Equipped with a 5¼" polypropylene woofer for superb low frequency response (bass) and a 1"pivoting titanium tweeter for excellent high sound separation.

A Few Tips on Whole House Speaker Placement
In rooms where you are others will be moving around a lot or frequently entertain in, speaker placement for critical listening won’t work. The music will be too loud in one area and too soft in another. Rooms larger than 300 square feet should use at least two pairs of speakers. Rooms less than 300 square feet, speakers should be placed near opposite corners. For hallways, walk-in closets and bathrooms where space will only allow a single speaker, we recommend using a stereo input speaker.

What Kind of Speaker Wire Should I Use?
Wiring requirements will depend on your local building codes, but OSD Audio offers CL3/FT4 cable that is UL (fire) rated for all residential and most commercial in-wall and in-ceiling applications. (The exception is you cannot run this cable in heating or cooling ducts in commercial applications.) This 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.

For a retrofit installation, no construction bracket is needed.
