SI-28

SI-28

The SI-28 is a 2 way full range system with an internal passive crossover that provides exceptional bandwidth and output SPL in a single system package. With nominal 70 degree coverage pattern, the system can be arrayed for additional coverage and SPL.

The Waveguide HF section provides consistent coverage over its specified range for low feedback in open mic applications and improved array smoothness. Speech articulation and sonic accuracy are inherent to the SI- 28.

The enclosure design allows for installation in tight spaces, very close to walls and ceilings, making it the ideal choice for under balcony, column and wall mounting. There are a total of twenty M8 thread fly points on the sides top and bottom to ensure easy installation in both horizontal and vertical applications. The enclosure also provides rigging point spacing for use with Omni-Mount™ type brackets.
