Side- or rear-mounted speakers in a multi-channel audio system pose a radically different set of performance challenges relative to conventional stereo systems, because surround speakers are typically positioned much closer to the listener and deliver sound to the ears from very different angles.
 
The proprietary M&K Sound Tripole® configuration, essentially two speakers mounted in a single cabinet, is the first and only technology to effectively address these major issues to deliver both image specificity and an enveloping surround field, without compromise.
 
The M&K Sound S150T Tripole® THX combines both front and side mounted drivers to direct the surround image both indirectly and directly into the listening area.
