4-Way Screen Channel Loudspeaker, Tri- or Quad-amp
Flyable 4-way tri-amplified screen channel speaker system
Constructed of heavily braced, 15 mm tour-grade plywood
Sixteen M10 attachment points per enclosure for safe and easy suspension
Common dimensions of Mid/High and LF enclosures facilitate easy installation in vertical or horizontal arrays
Unique HF/VHF diaphragm has less mass than traditional diaphragms resulting in exceptional dynamic range, extended high-frequency response and lower distortion
Low-distortion waveguides provide highly articulate dialogue
Suspension hardware not included; must be supplied by installer
