The SI-15X speaker has been designed for unobtrusive fixed installation, where sonic accuracy, detail and high SPL are essential characteristics.

With this speaker you have what it takes to assemble the system that your music deserves. With both barrier strip and 2 x NL4 (speakon compatible) connectors, the SI-15X also offers versatility when making the connections.

An important factor in loudspeakers is the smoothness of the sound coverage. Many speakers that may sound acceptable in the horizontal plane have problems in the vertical plane. The SI-X speakers exhibit very smooth and well-behaved sound dispersion characteristics in both the horizontal and vertical planes making positioning and set-up less critical. Everyone in the room will hear the same quality sound.

Because of the multi-faceted cabinet design, the SI-15X speaker can be positioned on the floor as a stage monitor or mounted on a wall or ceiling (using the U-shaped brackets included with the speaker).

The rugged cabinets feature 20 x M8 threaded inserts to facilitate the safe installation of the loudspeaker and are available in black or white durable paint finishes.
