Key Features
• High-performing, powered, portable two-way loudspeaker system with
a 195° H x 10° V nominal dispersion designed for the production and
reproduction of live music, music playback, speeches and A/V sound
reproduction
• 12-driver articulated line array produces wide, uniform sound
coverage throughout the entire listening area—even off to the extreme
sides
• Consistent front-to-back coverage, 12 drivers mounted in a vertical
line array produce less drop off in sound pressure level per doubling in
distance than a conventional point source
• Retractable folding leg mechanism for easy transport
• Lightweight, interlocking components
• Expandable bass design supports the use of multiple B1 bass modules
or a single B2 module
• Digital ethercon port provides single-wire connectivity for the T1
ToneMatch audio engine
