Immersive 150 Series Tripole Surround Sound in a Discreet In-Wall Design
The M&K Sound IW150T Tri-pole In-Wall Speaker (Pair) delivers the enveloping surround performance of M&K Sound’s renowned S150T in a discreet architectural format. Each speaker combines a direct-radiating front woofer and tweeter with two side-firing drivers, producing precise effects placement together with the spacious, diffuse sound field preferred for cinematic surround channels.
Designed for advanced Dolby Atmos, DTS:X and multichannel home theater systems, the IW150T uses a sealed enclosure to maintain predictable performance regardless of wall-cavity construction. Its shallow cabinet, solid steel baffle and paintable magnetic grille allow the speaker to integrate cleanly into dedicated theaters, media rooms and high-performance living spaces.

Technology & Design
Three-Sided Sound Radiation — A front-mounted 5.25-inch woofer and 1.1-inch silk-dome tweeter reproduce focused surround information, while two side-mounted 2.35-inch drivers expand the sound field across the room.
Phase-Focused Crossover — M&K Sound’s crossover technology integrates the front and side drivers for consistent timing, tonal balance and spatial presentation throughout the seating area.
Sealed Architectural Cabinet — The enclosed design isolates the drivers from unpredictable wall cavities and provides controlled response down to 60Hz within a compact 3.74-inch mounting depth.
Steel Baffle and Magnetic Grille — A rigid powder-coated steel fascia reinforces the installation, while rubber-coated neodymium magnets secure the low-profile paintable grille without visible fasteners.
