The loudspeaker system shall be a horn-loaded, 2-way design with a 12" paper cone and moisture resistant coating.

The loudspeaker system shall include a 12”, horn loaded, cast frame woofer and an integral, concentrically mounted 1” exit compression driv- er coupled to a constant directivity high frequency horn. The three pole (18 dB/octave) dividing network shall have a crossover frequency of 1.8 kHz. The dividing network shall include a poly switch protection circuit for the high-frequency component.

The loudspeaker system shall be capable of providing a sound dispersion angle of 65˚ horizontal by 65˚ vertical in the 2 kHz octave band.

Rated power shall be 200 watts RMS based on EIA Standard RS-426B.*

Enclosure shall be UV-resistant, low pressure injection molded fiberglass and shall include a 3 stage multiple mesh filter system for weather and rodent resistance: to include a 20-gauge perforated aluminum screen on front mouth assembly, a 100 x 100 weave stainless steel mesh between HF horn and HF driver and a 100 x 100 weave stainless steel mesh over 12” woofer. The loudspeaker shall include a stamped and formed, 2 mm stainless steel powder coated mounting bracket assembly for surface mounting and three M8 drop forged eyebolts for suspension mounting two at the front and one at the rear to allow the speaker system to be suspended and aimed using rated wire rope.

Sensitivity shall be 101 dB SPL (80 Hz – 15 kHz in 13 octave bands) measured at a distance of 1 meter on axis with a 1 watt input half space (2.83V).

Overall frequency response shall be 80 Hz – 15 kHz (±5 dB).

The input section located on the bottom rear of the loudspeaker shall be via 7 position screw down terminal strip internally configured to allow input to an internally mounted 70.7 V transformer with 7.5, 15, 30, & 60 watt taps and a by-pass jumper for direct coupled to the speaker for nominal 8 Ω operation. The system connections shall be protected from the elements by a screw affixed weather resistant cover.

Dimensions shall be: Height: 23.88” (606.55 mm) Width: 21.41” (543.81 mm) Depth: 22.57” (573.28 mm) Weight: 130 lbs (58.97 kg)

The AH94-12ST and AH94-8ST are part of Atlas Sound's advanced loudspeaker series, featuring weather-resistant construction ideal for both indoor and outdoor use. The AH94-12ST boasts a 12-inch woofer and a titanium dome high-frequency driver, providing impressive sound transmission over large areas. This model is well-equipped for large venues, ensuring rich bass and clear highs, perfect for music playback and speech intelligibility. In contrast, the AH94-8ST, with its 8-inch woofer, offers a slightly lighter option without sacrificing sound quality, making it suitable for smaller rooms where full-range sound is still required.

The AH66-8ST and AH66-12ST models enhance versatility with their dual-impedance configurations, allowing easy integration into existing audio systems. The AH66-12ST features a larger woofer that delivers deeper bass response, ensuring that music and speech are delivered with full fidelity. The AH66-8ST, being more compact, serves well in applications where space is a premium, yet still offers the same high-quality sound performance.

Lastly, the AH99-8ST stands out with its wide coverage pattern and increased power handling capabilities, designed to distribute sound evenly across larger areas. This makes it an ideal choice for installations where wide dispersion and volume control are key, such as gymnasiums or large assembly halls.

All these speakers incorporate advanced technologies including neodymium magnets, mounting options for flexible installation, and durable enclosures designed to withstand the rigors of professional use. They also come equipped with high-efficiency voice coils, ensuring high output while maintaining minimal distortion.

In summary, the Atlas Sound AH94, AH66, and AH99 series speakers are essential tools for professional audio applications, providing superior sound quality, innovative features, and reliable performance for various settings.
