The OSD-IW520 are exceptional in-wall speakers for the price. Features normally found on speakers costing much more include a 5.25'' carbon-filled polypropylene woofer and PEI dome tweeter for smooth, clear background audio. This is a great speaker for if you need to fill a large area with background music but don't want to blow your entire budget on speakers. Customers are often amazed that an in-wall speaker in this price range could be such high quality but the proof is there when they turn on their system.

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 d'cor. 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 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.
