Description
The Soundsphere Q-12A omnidirectional loudspeaker from SoundTube provides a more powerful sound system where clear voice announcements and high-fidelity foreground music are required at high sound pressure levels.
Broad dispersion of all frequencies is achieved with a 12” true coaxial driver where LF and HF share a common magnetic circuit and proprietary dispersion technologies. Along with a hemispherical coverage pattern that covers a large area with fewer speakers,the Q-12A utilizes our exclusive patent-pending Poly- Exponential Incidence Reflector. It comes fully assembled and ready to mount using our hanging kit or mounting bracket.
The Soundsphere Q-12A is available in a weatherproof configuration (Q-12AWR) for outdoor use, featuring a protective screen over the holes and driver to prevent birds from nesting in the speaker.

Features

Hemispherical coverage pattern.
Accurate, full-range voice announcements.
Enhanced high-fidelity music reproduction.
High sensitivity (94 dB 1 W / 1 M).
High SPL capability (118 dB @ 1 M).
Exclusive patent-pending Poly-Exponential Incidence Reflector.
Hanging or surface-mount.
Standard white (paintable) available
1. Impedance listed per IEC 60268-5 with a minimum less than 80% the nominal impedance
2. 1 W / 1 M sensitivity determined using nominal impedance
3. Frequency response measured in half or full space as dictated by speaker mounting configuration
4. Max program power is 3 dB above max continuous power
5. Continuous power rating, EIA-426-B test
6. Max output based on max continuous power

Applications

Providing high-power, high-fidelity foreground music and voice, the Soundsphere Q-12A loudspeaker is ideal for applications such as gymnasiums, ice rinks, arenas, churches, swimming pools, transportation terminals, factories, open public areas, bars/nightclubs and anywhere that clear voice announcements and high-fidelity foreground music are required at high sound pressure levels.
