Now multi-channel audio enthusiasts can enjoy MK Sound Tripole® technology in an even more practical size with the SUR-55T Tripole Speakers. This breakthrough design shares all of the technologies and is timbre matched to the rest of the 750THX system.

The MK Sound Tripole speakers featuring two 3” paper mid-tweeters on each side of the speaker oriented in dipole fashion, the dipole configuration emits diffused sound throughout the room. Combined with the front-mounted 1” soft-dome tweeter and 5.25” polypropylene mid-woofer direct radiating configuration (the same drivers as in the LCR-750 and Center 750), the Tripole® design provides even distribution of sound throughout the listening area with pinpoint accuracy and an enveloping sound field, allowing listeners to experience superior imaging and surround quality.

The MK Sound SUR-55T is a Tripole™ Surround loudspeaker with forward firing two-way array utilizing a 1” polymer coated silk soft-dome, ferrofluid cooled neodymium magnet tweeter and a 5¼” mineral-filled polypropylene cone, magnetically shielded cast basket woofer, combined with two side firing 3¼” coated pulp cone, magnetically shielded full range drivers. Featuring MK Sound’s proprietary Phase-Focused™ Crossover, it provides extraordinarily even dispersion of sound throughout a broad listening area with superior imaging and sound quality. The MK Sound SUR-55T is timbre-matched to the LCR-750 and LCR-750C for a rock-steady consistent surround sound field with seamless transitions as voices and sound effects move across or through the three-dimensional soundstage.

The MK Sound SUR-55T speakers are available in a black vinyl finish with black metal mesh grille.
