The FONESTAR TOWER-20TB is a compact sound column speaker (sound projector) engineered for public address installations where focused sound, speech clarity, and resistance to reverberation are paramount. With a slim, elegant profile and robust construction, it is ideal for covering large, challenging acoustic environments.
Optimized for Voice: The column design is specifically tuned for voice playback, maximizing clarity and directing sound to the audience area. This focused directivity helps to significantly reduce acoustic coupling (feedback) and reverberation.
Compact Power: Delivers 20 W RMS power from four 2 ½" speakers in a slender enclosure, offering high acoustic performance in a small footprint.
Durable Construction: Built with an aluminum enclosure and grille, making it resistant to rust and ensuring a long service life with minimal maintenance.
Versatile Installation: Features IP-44 protection, suitable for installation under cover in outdoor areas, as well as high-reverberation indoor spaces like conference rooms, religious centers, and theatres.
PA System Integration: Incorporates a 100 V line transformer for simple and scalable integration into distributed sound systems for both voice and background music.
