Reference Tripole Surround Performance for Immersive Home Theater
The M&K Sound S150T Tri-pole Surround Speaker (Pair) delivers the combination of precise effects placement and enveloping ambience required for a convincing cinematic surround experience. Each speaker combines a front-firing 5.25-inch fiberglass bass/midrange driver and 1.1-inch soft-fabric-dome tweeter with two side-firing 3.5-inch drivers, allowing direct and diffuse sound to reach the listening area simultaneously.
Designed as the dedicated surround companion for M&K Sound’s reference 150 Series, the S150T is voice matched to the S150 front-channel monitor for smooth tonal transitions around the room. Its compact trapezoidal cabinet is engineered for side- or rear-wall placement, where conventional direct-radiating speakers can become overly localized and distracting.
