LT2-830-T870-Vb

2x2 Speaker System for Tile Ceilings

• Includes 8" coaxial driver, transformer, 2x2 grille/subplate, volume backbox

Quick install speaker system for suspended tile ceilings
features an 8" coaxial driver, 70V transformer, 2'x2' fine
perforation grille with subplate and volume backbox. This
system is ideal for foreground music.

Features

• Driver (CT830A): 8" 20W coaxial driver with 12 oz.
magnet, frequency response of 57Hz-14kHz (+6dB),
44Hz-20kHz (+7.6dB) and sensitivity of 97.0dB avg.
measured 1W/1M.

• Transformer (TLM-870): 70V transformer has primary
taps at 1, 2, 4, and 8W.

• Grille with subplate (2'x2'): Fine-perforation grille is
designed to provide maximum free-air space for ex­cellent sound transmission while maintaining an unob­trusive appearance in new or existing tile ceilings.
Quick install. White finish.

• Volume Backbox: 0.8 cu.ft. steel backbox with acoustic
lining enhances audio performance. Speaker leads
exit through a metal clamp for fast connection—just
splice connecting wires, push them inside the enclo­sure and tighten the clamp. Black finish.
