SoundTube Q-12A Omnidirectional Loudspeaker, White

The Soundsphere Q-12A delivers exceptionally high sound pressure levels with uniform 360° dispersion, making it ideal for gymnasiums, arenas, industrial facilities, and other large indoor spaces where clear voice paging and high-fidelity music are required. Its patent-pending Poly-exponential Incidence Reflector enhances efficiency and smooth frequency response.

Featuring a 12″ treated-paper coaxial woofer and a 2″ titanium-diaphragm compression driver, the Q-12A provides 97 dB sensitivity (1 W/1 m) and up to 121 dB SPL at 250 W (1 m). Wire-lead tap connections allow integration into 25 V/70.7 V/100 V constant-voltage systems.
