(standard configuration)
Dual 15-lnch Two-Way
System for Permanent
Installation, Hom Loaded HF
• Part of PI Matrix SeriesTL....compact
trapezoidal systems for permanent
installation
• Components and physical
characteristics optional, to meet many
acoustic, architectural and
mechanical requirements
• 45-Hz low end for speech and many
music applications
• Stacked 15-inch woofers provide
high mid-band directivity-for higher
intelligibility in difficult acoustics
• Three HF coverages-60° x 40°
(standard), 60° x 60° or 90° x 40°
• PROTM circuit HF protection
• For biamplification (standard);
passive network optional
• Integral suspension system for safe
and installation
