M&K Sound SUR55T (Pair)

SUR55T THX Tripole Surround Sound Rear Speakers



The SUR55T is the most compact THX Tripole® solution M&K offer and is timbre matched to any of the 750 Series speakers.

Ultra-compact speaker featuring M&K’s new 750 Series components, together with 2 dedicated side drivers operating in a dipole fashion,
providing the most optimal cinematic surround sound available.

Featuring two 3” mid-tweeters on each side of the speaker oriented in dipole fashion, combined with the front-mounted 1” soft-dome tweeter and a 5.25” midwoofer direct radiating, the SUR55T provides even distribution of sound throughout the listening area with pinpoint accuracy and an enveloping soundfield.

The 750 Series takes the THX Select category to new a level and we are proud to introduce a true acoustic upgrade, in the form of M&K’s own customized Danish designed and produced tweeters.
