MK Sound SUR-55T THX Select Tripole Surround Speakers, breakthrough design shares all of the technologies and is timbre matched to the rest of the 750 THX system. Featuring two 3” paper mid-tweeters on each side of the speaker oriented in dipole fashion, the dipole configuration emits diffuse 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 original THX program was created to ensure that movie theatres meet strict quality standards. The THX logo immediately became recognized as a seal of approval for quality-conscious cinema-goers around the world.

For the home theater enthusiast, the independent THX Select quality standard ensures high performance in listening environments under 2,000 cubic feet. The 750 THX system meets and exceeds THX Select specifications for flat on-axis frequency response, wide and even horizontal dispersion and coverage of a large listening area with consistent tonal character.
