    Wall-mounted linear column loudspeaker designed for professional public address systems where uniform sound coverage, high speech intelligibility, and precise directivity control are required. Thanks to its narrow vertical (20°) and ultra-wide horizontal (120°) sound dispersion, this speaker is ideal for long corridors, halls, conference spaces, and auditoriums.

    The speaker is equipped with 4 × 3" drivers forming a linear array that reduces echo and improves speech clarity. Its robust construction with an aluminum grille and rust-protected ABS enclosure ensures durability and a professional appearance in demanding installations.
