SOUNDSPHERE Q-12A Powerful Omnidirectional Loudspeaker Owner’s Manual

Q-12A PRODUCT SPECIFICATIONS

Description

The Model Q-12A omnidirectional loudspeaker 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 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 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.

Architectural Specifications

The loudspeaker driver shall consist of one 12” (304.8 mm) treated pulp fiber woofer with a 2.8” (72 mm) titanium compression driver sharing a common magnetic circuit.

Performance specifications of a typical production unit shall be as follows:
Usable frequency response shall extend from 65 Hz – 15 kHz. The vertical polar coverage shall be 155° ±6 dB. Measured sensitivity (1 W / 1 M) shall be at least 94 dB. The speaker shall have a rated impedance of 4 Ω. The speaker shall be available for 70 and 100 V modes and shall include 4 power tap selection leads for use with electrical wire nuts or crimp caps.

Rated power capacity shall be at least 250 W continuous RMS and conform to EIA-426-B testing. Calculated maximum continuous output at 1 M and shall be 1138 dB.

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.

Optional accessories shall include: a 250 W Line Matching Transformer (TX250) with taps for 70 and 100 V constant voltage systems; a Mounting Bracket (MBL) to mount flat against a ceiling surface; a three-element Hanging Kit (HKL) for single-point suspension; a 24” Hanging Kit Extension (HKEXT); a Universal Beam Clamp (BCL); a Large Screen (SL) to protect the speaker from foreign objects; and a Large Screen with Weather Filter (SWFL) that additionally offers a water protection barrier.

The system Shall be the Soundsphere Model Q-12A for wide-range, widecoverage sound dispersion at high sound pressure levels.

Warranty

Soundsphere loudspeakers are warranted against failure or malfunction due to defects in materials or workmanship for a period of five years from date of original purchase.
