Reference 150 Series Performance in a Discreet In-Wall Design
The M&K Sound IW150 In-Wall Speaker brings the accuracy, dynamics and precise imaging of M&K Sound’s renowned 150 Series into a clean architectural format. Its vertically aligned array combines two 5.25-inch polypropylene bass/midrange drivers with three 1-inch soft-fabric-dome tweeters for clear dialogue, focused imaging and consistent sound throughout the listening area.
Designed for serious home theaters and high-performance media rooms, the IW150 can be used for left, center or right channels behind an acoustically transparent screen or around a flat-panel display. Its integrated enclosure provides controlled acoustic performance, while the frameless paintable grille allows the speaker to blend discreetly into the surrounding wall.
