SI SERIES OVERVIEW:
The SI Series comprises of the SI-10, SI-12, SI-15 and SI 28 full range systems plus two subwoofers - the SI15B
and the SI-18B.
SI-10, SI-12, SI-15 and SI 28:
All the full range models are two way systems with an internal passive crossover providing high level , high
definition performance in a compact enclosure. With a nominal 70 degree coverage pattern, the system can be
arrayed for additional coverage and SPL requirements. The elliptical waveguide HF section provides consistent
coverage over its specified range for low feedback in open mic applications and improved array smoothness. M8
flypoints (20 in total) on the top, bottom and sides allow ease of installation in both horizontal and vertical
positions. The unique 5 sided multi-angle shape of the SI-10 makes it perfect for low profile ceiling mounting (or
corner installation) or as a compact floor monitor.
SI-15B, SI-18B Subwoofers:
The SI-15B and SI-18B are compact sub bass systems designed for use with the SI-15, SI-12 and SI-28 full
range loudspeakers in applications where extended low frequency output and increased system headroom are
required. These powerful systems are capable of delivering high sound pressure levels with very low distortion
over sustained periods. Superior output in extreme conditions is maintained through the use of effective
dissipation mechanisms, avoiding the loss of power compression often found in other systems.
