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.

Unfortunately, most multi-channel installations ignore these critical factors entirely and simply employ the same type of direct-radiating monopole drivers that have been the norm for well over a century. These conventional loudspeakers feature drivers mounted on one side only (monopole) and aimed directly at the listening position. As a result of the close proximity to the listening area, they are easily identifiable as the source of sound, failing to disappear in a credible you-are-there sonic illusion.

A costly alternative in recent decades is the dipole surround speaker with no drivers on the front directly facing the audience, but identical sets of drivers on two sides. By generating sound from one side in phase and the other out of phase (dipole) with no sound radiating directly at the listening position, dipoles successfully create a diffuse soundfield, but at the expense of any sound actually intended to be heard as a specific image.

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 Miller & Kreisel S150T THX Tripole combines both front and side mounted drivers to direct the surround image both indirectly and directly into the listening area, for a smoother, more robust surround image in perfect harmony with the front three channels. Because the S150T THX Ultra2 Tripole employs the same exclusive, innovative high frequency driver as the Miller & Kreisel S150, THX Ultra2, sonic consistency and voice matching are assured.
