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.

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.
Patented Technologies
SoundTube constantly develops new technologies which enhance audio
product performance. SoundTube innovations are protected by multiple U.S.
and international patents, which explicitly cover Soundtube’s enclosure and
dispersion technologies. SoundTube actively defends its patents in order to
protect SoundTube resellers and end-users.
The complete loudspeaker shall be no more than 25” (635 mm) in height.
The driver shall be mounted in a spherical enclosure made of fiberglass with
gelcoat finish that is no more than 22” (558.8 mm) in diameter. The reflector
shall be no more than 26” (660 mm) in diameter. The complete loudspeaker
shall weigh no more than 39 lbs (17.6 kg). Hardware shall be rust and
corrosion-resistant, constructed of stainless steel, plated steel, or aluminum.
