Krix KX1550 Cinema Stage Surround Speaker


The Krix KX-1550 cinema surround loudspeaker offers very high power handling, very high efficiency. The KX-1550 can accept an undistorted signal from an amplifier with a power rating of up to 500 watts RMS.

It features a dual concentric loudspeaker that essentially eliminates phasing problems in the crossover region associated with conventional driver layouts. It has provisions for wall mounting and accepts the KX-9061 bracket.

The high frequency driver utilises a titanium dome with 3" voice coil and has a 90 degree conical dispersion pattern. The bass driver is a 12" paper cone with a nominal 4" voice coil for smooth, deep bass response at high power.

It features a 15 degree front baffle angle to ensure smooth, accurate performance with high dynamic sound reproduction and reliability. Typically the audience seated in the area below the surround would experience deep voids, diminishing the movie going experience. This alignment minimises the deep off axis cancellation problems normally associated with two way systems of this type.
