Atlas Sound ALA15T – 15-Driver Full Range Column Line Array Speaker

Product Overview

The AtlasIED ALA15T is a full-range column line array speaker system engineered for superior speech intelligibility and even sound coverage in commercial AV and distributed audio applications. Combining fifteen 3-inch full-range drivers and four 3/4-inch high-frequency tweeters in a slim extruded aluminum housing, this 70V line array loudspeaker delivers 135-degree horizontal by 40-degree vertical coverage — making it an effective choice for boardrooms, houses of worship, auditoriums, and training rooms where intelligibility across the listening area is critical.

Product Description

The ALA15T column line array loudspeaker is designed to deliver maximum acoustic performance in a minimal physical footprint, addressing the common challenge of achieving consistent sound coverage in reverberant or architecturally constrained commercial spaces. The 15 tightly packed 3-inch full-range proprietary drivers work in concert with four 3/4-inch high-frequency tweeters to produce smooth, extended frequency response from 90 Hz to 20 kHz at 96 dB sensitivity. The result is a speaker capable of delivering clear, intelligible speech reproduction across large audiences without the sightline obstruction of a traditional large-format enclosure.

The extruded aluminum housing provides both structural durability and IP32 environmental resistance, appropriate for indoor commercial installations with occasional moisture exposure. The rear of the enclosure incorporates vertical mounting channels that accept the included wall bracket, allowing installers to slide the mount to any position along the enclosure height to achieve the desired vertical tilt — simplifying aiming without additional hardware. An optional pole mount bracket enables portable deployment alongside the A-Line subwoofer series for live sound reinforcement applications.

The ALA15T includes an integrated transformer supporting 70.7V/100V distributed audio operation with selectable power taps of 7.5, 15, 30, and 60 watts, as well as direct 8-ohm operation at 250 watts RMS. Both NL-4 and barrier strip input terminals are provided. The speaker is rated for 600 watts recommended amplifier power and achieves a peak SPL of 120 dB, making it capable of providing substantial output levels in larger spaces. A five-year warranty is standard.

Frequently Asked Questions

Q: Does the ALA15T support 70V distributed audio wiring?

A: Yes. The ALA15T includes an integrated 70.7V/100V transformer with selectable power taps of 7.5, 15, 30, and 60 watts, making it fully compatible with standard 70V distributed audio amplifier systems used in commercial installations.

Q: Can the ALA15T be used in portable applications?

A: Yes. An optional pole mount bracket allows the ALA15T to be used in portable configurations alongside the AtlasIED A-Line subwoofer series for live sound or portable event reinforcement applications.

Q: How is the vertical tilt of the wall mount adjusted?

A: The rear of the enclosure features vertical channels that accept the included wall bracket. The bracket slides to any position along the enclosure height, providing stepless adjustment of vertical tilt to aim the coverage pattern at the listening area without additional hardware.

Q: What amplifier power is recommended for the ALA15T?

A: AtlasIED recommends 600 watts of amplifier power for the ALA15T. The speaker is rated at 250 watts RMS at 8 ohms.

Q: Is the ALA15T suitable for outdoor use?

A: The ALA15T carries an IP32 rating, which provides protection against dripping water in a vertical direction. It is intended primarily for indoor commercial use and protected outdoor applications where direct rain or water immersion are not expected.

Q: What input connection types are provided?

A: The ALA15T includes both a barrier strip terminal and an NL-4 (Speakon) connector, supporting standard commercial permanent wiring and touring-style connector systems.

Q: What is the warranty on the ALA15T?

A: The AtlasIED ALA15T is backed by a 60-month (5-year) limited warranty from date of purchase.
