Atlas Sound AH54-15-BSG 15" 2-Way Stadium Horn Speaker System 50° x 40°

Product Overview

The AtlasIED AH54-15-BSG is a 15" 2-way stadium horn speaker built for long-throw, directional sound distribution at football stadiums, sports arenas, baseball fields, convention centers, and large auditoriums. Its constant directivity design holds a tight 50° horizontal by 40° vertical coverage pattern, putting full-range audio and announcements exactly where the audience sits. With 250 watts of power handling and 128 dB maximum output, it delivers the sound pressure levels an outdoor stadium sound system installation demands while maintaining speech intelligibility.

Product Description

The AH54-15-BSG pairs a 15" cast frame woofer with a concentrically mounted 1" exit compression driver coupled to a 50°H x 40°V high-frequency horn, producing full-range reproduction from 75 Hz to 14.5 kHz in a single weatherized enclosure. That narrower 50° x 40° pattern makes it the long-throw option in the AH series, well suited to covering bleachers and far seating sections from scoreboard or light-pole mounting positions in an outdoor PA system design. Weather-resistant construction includes a multiple-screen configuration: a perforated aluminum screen across the large horn mouth, a secondary screen forward of the high-frequency driver, and a third tightly perforated screen protecting the woofer. A weep hole on the back of the horn bell lets internal condensation evaporate rather than accumulate, and the speaker carries an IP54 rating. System impedance is a nominal 8 ohms, with 70.7-volt distributed line operation available via the optional Atlas Sound AF140 transformer, so the horn fits both low-impedance amplifier channels and 70V commercial paging system installations. A heavy-duty stainless steel mounting bracket is included for flat-surface installation, and a weather-resistant parallel 4-pole terminal block simplifies wiring in the field. For amplifiers, transformers, and companion horns for your stadium audio project, see the AtlasIED collection at Creation Networks.

Key Features

• 250W Power Handling — Handles 250 watts RMS for high-output announcements and music in large outdoor venues.
• 50° x 40° Constant Directivity Coverage — Controlled 50° horizontal by 40° vertical pattern (2 kHz octave band) concentrates energy on the seating area for long-throw applications.
• Full-Range 2-Way Design — 15" cast frame woofer plus 1" exit compression driver reproduce 75 Hz to 14.5 kHz for intelligible voice and usable music playback.
• High Output — 104 dB sensitivity (1W/1M) and 128 dB maximum output at rated power reach distant seating without strain.
• Weather-Resistant Construction — Triple-screen moisture protection, weep hole drainage, and IP54 rating support permanent outdoor installation.
• Flexible Impedance Options — 8-ohm nominal operation, with 70.7V distributed line use via the optional AF140 transformer.
• Included Mounting Hardware — Heavy-duty stainless steel bracket allows installation to most flat surfaces.
• Field-Friendly Wiring — Weather-resistant parallel 4-pole terminal block speeds connection and loop-through wiring.

Typical Applications

• Auditorium
• Multi-purpose room

Primary deployments are outdoor venues: football stadiums, sports arenas, baseball fields, fairgrounds, and convention centers.

Technical Specifications

Frequently Asked Questions

Can the AH54-15-BSG run on a 70V distributed audio system?

Yes. The horn is a nominal 8-ohm speaker, and adding the optional Atlas Sound AF140 transformer enables 70.7V operation for distributed commercial paging and stadium PA lines.

Is this stadium horn rated for permanent outdoor installation?

Yes. It carries an IP54 rating with a triple-screen moisture barrier and a weep hole in the horn bell that lets condensation evaporate, making it suitable for year-round outdoor mounting.

How does the 50° x 40° pattern compare to other AH series horns?

The 50° x 40° pattern is the long-throw option, concentrating output on distant seating. For wider, shorter-throw coverage, AtlasIED offers the AH99-12T-BSG with a 90° x 90° pattern, also available at Creation Networks.

What mounting hardware is included?

A heavy-duty stainless steel bracket for flat-surface installation is included, and forged eyebolts support suspended installation per the manufacturer's guidance.

What amplifier should drive this horn?

Size the amplifier to the 250W RMS rating at 8 ohms, or use a 70V amplifier channel with the AF140 transformer. Our team can help spec AtlasIED amplifiers for your venue before you order.

What warranty does AtlasIED provide?

The AH54-15-BSG is covered for 60 months from the date of purchase under the AtlasIED limited warranty.
