The SI-X™ Series –– Foreground/Background Music And Sound Reinforcement Speakers
The SI-X Series is a versatile fixed installation loudspeaker system designed for surface mount or flown applications. The angled low profile enclosures are designed to provide high SPL in an unobtrusive package.
Consistent voicing across the range ensures seamless coverage when using a variety of different models in distributed sound applications. All SI-X Series models feature a 1” exit compression driver on a 70°x 70° conical waveguide providing open and detailed high frequency extension with even and predictable dispersion.
Because of their multi-faceted design the SI-X speakers 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 public houses.
The SI-X Series includes full range enclosures with woofer sizes ranging from 10” to 15”, a dual 8” woofer model is also available.
