Atlas Sound ALA10T – Passive 400W Column Line Array Speaker (Black)

Product Overview

The Atlas Sound ALA10T is a passive 2-way column line array speaker system designed for commercial speech reinforcement applications requiring exceptional intelligibility and controlled vertical dispersion. The ALA10T combines ten 3-inch full-range LF drivers and four 25mm HF tweeters in a sealed extruded aluminum enclosure, delivering a maximum 122dB SPL peak and a tight 135° H x 40° V coverage pattern well-suited to environments with high ceilings or reverberant acoustics. With 70.7V and 100V transformer taps, EN54-24 fire alarm system certification, and an included wall mounting bracket, the ALA10T is built for auditoriums, houses of worship, conference halls, and transportation facilities where speech clarity across large listener areas is the primary requirement.

Product Description

Column line array speakers concentrate vertical dispersion to reduce ceiling and floor reflections that degrade speech intelligibility in reverberant spaces. The ALA10T's 40° vertical coverage angle focuses sound energy toward the listening plane, minimizing energy that excites room modes and early reflections — a substantial benefit in hard-surfaced venues such as airport terminals, convention halls, and stone or concrete houses of worship. The 135° horizontal coverage provides broad lateral coverage without requiring multiple speaker positions per zone in typical commercial deployments.

The driver complement — ten 3-inch LF transducers and four 0.9-inch HF tweeters — is housed in a sealed line array enclosure with a 3.5kHz passive crossover. Input sensitivity is 96dB and frequency response runs 160Hz to 20kHz (±5dB), extending to 125Hz at -10dB. System impedance is 6 ohms. For 70V distributed audio systems, transformer taps are available at 60, 30, 15, and 7.5 watts on the 70V system, and 60, 30, and 15 watts on the 100V system, with a 6-ohm bypass available on both. Peak power handling is 400W (200W RMS) in direct 6-ohm mode.

The extruded aluminum enclosure is lightweight and durable, with contemporary styling that integrates cleanly into architectural interiors without dominating the visual field. The rear of the enclosure features vertical channels that accept the included wall mount bracket, which slides to the desired vertical tilt position — a practical installation detail that allows tilt adjustment without separate hardware. An optional pole mount bracket enables use with portable subwoofer systems for temporary or touring deployments. The ALA10T carries EN54-24 certification, qualifying it for installation in fire alarm voice evacuation and public address systems in applicable jurisdictions.

Key Features

• Column Line Array Configuration — Ten 3-inch LF drivers and four 25mm HF tweeters in a sealed line array deliver controlled 40° vertical dispersion to minimize ceiling reflections and improve speech intelligibility.
• 122dB Peak SPL — High output capacity covers large listener areas without requiring multiple amplifier channels or speaker clusters.
• 135° H x 40° V Coverage — Wide horizontal and narrow vertical pattern provides broad lateral coverage while focusing energy on the listening plane.
• 70.7V and 100V Transformer Taps — Integrates directly into 70V distributed audio systems at 7.5, 15, 30, and 60 watt taps, with 6-ohm bypass for direct amplifier connection.
• EN54-24 Certified — Certified for use in fire alarm voice evacuation and public address systems in applicable jurisdictions.
• Extruded Aluminum Enclosure — Lightweight and durable construction suitable for permanent wall-mounted installation in demanding commercial environments.
• Adjustable Wall Mount Included — The rear channel system accepts the included bracket, which slides to the desired vertical tilt position for precise aim without additional hardware.
• Barrier Strip and Speakon NL4 Inputs — Dual input options support both standard commercial wiring practice (barrier strip) and professional amplifier connections (Speakon NL4).

Typical Applications

• House of worship main or front-fill speaker
• Auditorium speech reinforcement
• Conference room and all-hands room paging and audio
• Government and civic facility public address
• Training room distributed audio
• Multi-purpose room sound reinforcement

Frequently Asked Questions

Q: What makes a column line array better for speech intelligibility than a conventional point-source speaker?

A: Column arrays concentrate vertical dispersion to reduce energy hitting the ceiling and floor — the primary sources of early reflections that reduce speech intelligibility in reverberant rooms. The ALA10T's 40° vertical pattern focuses energy on the listening plane where it is needed.

Q: Is the ALA10T suitable for fire alarm voice evacuation systems?

A: Yes. The ALA10T carries EN54-24 certification, making it eligible for use in fire alarm voice evacuation and public address systems in jurisdictions that recognize EN54-24. Confirm applicability with your local AHJ.

Q: Can the ALA10T be used in a 70V distributed audio system?

A: Yes. The ALA10T includes a built-in transformer with 70V taps at 7.5, 15, 30, and 60 watts, and 100V taps at 15, 30, and 60 watts. A 6-ohm bypass is also available on both voltage systems for direct amplifier connection.

Q: How is the vertical tilt adjusted?

A: The rear of the enclosure features vertical channels that accept the included wall mount bracket. The bracket slides to the desired tilt position and locks, allowing vertical aim adjustment without separate hardware.

Q: Can the ALA10T be pole-mounted for portable use?

A: Yes. An optional pole mount bracket is available separately, enabling use with compatible portable subwoofer systems for temporary or touring applications.

Q: What warranty does the ALA10T carry?

A: Atlas Sound products carry the manufacturer's standard commercial warranty. Contact Creation Networks for current warranty terms and authorized service support.
