Unobtrusive audio

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

From the SI-10X to the SI-15X plus three high power subs, you have what it takes to assemble the system that your music deserves. With both barrier strip and 2 x NL4 (speakON compatible) connectors, SI-X 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-X speakers 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 SI-X Series 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.

Wide coverage

SI-X series is consistently voiced so multiple configurations depending on your venue, still result in a full, balanced sound. 

Full range models feature a 70° x 70° conical waveguide, providing open and detailed high frequency extension with even and predictable dispersion.

Adaptive cabinet design

The multi-faceted design of the SI-X series means that it can be positioned next to a stage, wall or ceiling. 

This versatility suits the SI-X series to a diverse range of applications such as live performance halls, houses of worship, schools, shops, restaurants bars and countless public places – for monitoring, front of house and more.

To suit any install

The full range enclosures are complimented by 3 subwoofers for extended low frequency response and increased SPL. 

Available in both black and white painted finishes, the SI-X series features multiple m8 rigging points to suit the widest range of flown applications. 

Brackets are included as standard too.

NL4 or Barrier strip

The rear panel of all SI-X models features speakON compatible (NL4) connectors…..plus a barrier strip for connection with bare wires.

Simple connectors – Simple installations.

Available in Black

Available in WHITE

Full metal bracket

SI-X Full range models (SI-10X, SI-12X and SI-15X) are supplied with U-shaped steel mounting brackets.

No more searching for 3rd party compatible wall mount hardware.  

The bracket comes in the box!
