Atlas Sound FS12T-66 12" FS Series Arena Horn with 65x65 degree dispersion

Product Overview

The AtlasIED FS12T-66 is a two-way, full-range arena horn speaker built for outdoor stadium sound systems and large indoor venues that demand intelligible voice and quality music reproduction in harsh conditions. Its 12-inch low-frequency driver and 1-inch exit compression driver mount concentrically on a high-directivity waveguide that delivers controlled 60-degree by 60-degree coverage. An integrated 400-watt 70.7V transformer with 4-ohm bypass ties directly into distributed 70V loudspeaker systems. The IP45-rated all-weather enclosure keeps it performing season after season.

Product Description

The FS12T-66 was engineered for venue paging and program audio where weather resistance is non-negotiable. The coaxial arrangement of a 12" LF driver and 1" exit HF compression driver on a constant-directivity waveguide produces a tightly controlled 60° x 60° pattern, letting system designers aim energy at seating areas while keeping it off reflective surfaces — a key consideration in stadium PA system design and reverberant indoor arenas. Sensitivity of 102.5 dB SPL and a maximum output of 128.5 dB SPL provide the throw and headroom needed for crowd noise.

The enclosure is molded from linear low-density polyethylene (LLDPE), giving the cabinet exceptional strength at a manageable 48-pound weight for an outdoor horn loudspeaker of this output class. A stainless steel U-bracket and integral fly-points support wall, pole, and flown commercial speaker installation at flexible aim angles, and the easy-service design lets technicians replace transducers in the field without removing the enclosure from its mount — a real labor saving on catwalks and lifts.

Electrically, the integrated 70.7V transformer offers low insertion loss and full frequency response with taps at 400, 200, 100, and 50 watts plus a 4-ohm bypass for low-impedance amplifier channels. The transformer mounts discretely under the rear cover for weather protection. The UV-resistant battleship grey finish (Pantone 423 C / RAL 7045) blends into structural steel and concrete environments common in arenas, fairgrounds, racetracks, theme parks, convention centers, and aquatic centers.

Key Features

• Constant-Directivity 60° x 60° Coverage — The high-directivity waveguide places sound on the audience and keeps it off reflective surfaces for clear announcements.
• Integrated 400 W 70.7V Transformer — Taps at 400/200/100/50 W plus a 4-ohm bypass connect to distributed 70V systems or direct amplifier channels.
• High Output for Large Venues — 102.5 dB sensitivity and 128.5 dB max SPL cut through crowd noise in arenas and stadiums.
• IP45 All-Weather Construction — Molded LLDPE enclosure and weather-protected transformer withstand year-round outdoor exposure.
• Coaxial Two-Way Design — 12" LF driver with 1" exit HF compression driver delivers full-range voice and music from a single point source.
• Stainless Steel U-Bracket and Fly-Points — Multiple rigging options support versatile aiming angles in permanent installations.
• Field-Serviceable Transducers — Drivers can be serviced without uninstalling the enclosure from its mount, reducing maintenance labor.
• UV-Resistant Neutral Finish — Battleship grey (RAL 7045) resists fading and blends into structural environments.

Typical Applications

• Auditoriums and indoor arenas requiring long-throw, pattern-controlled coverage
• Multi-purpose rooms and gymnasiums with high ambient noise
• House of worship outdoor overflow and parking lot audio
• Government spaces and campuses with outdoor mass notification zones

Frequently Asked Questions

Can the FS12T-66 be used outdoors year-round?
Yes. The molded LLDPE enclosure carries an IP45 environmental rating, the transformer is protected under the rear cover, and the UV-resistant finish withstands seasonal exposure.

Does it work on a 70V distributed system?
Yes. The integrated 70.7V transformer provides 400, 200, 100, and 50-watt taps with low insertion loss, plus a 4-ohm bypass for direct low-impedance amplification.

How is it mounted?
A stainless steel U-bracket is included, and built-in fly-points support rigged installations, allowing flexible aiming on poles, walls, catwalks, and structural steel.

Can drivers be replaced after installation?
Yes. The easy-service design allows transducers to be serviced in the field without removing the enclosure from its mount.

How does the 60 x 60 pattern compare to the FS12T-94?
The FS12T-66 provides a symmetric 60° x 60° pattern for longer-throw, tighter coverage; the companion FS12T-94 provides a wider 90° x 40° pattern for broad, shallow coverage areas. Many venue designs combine both.

What warranty applies?
AtlasIED warrants the FS12T-66 for 60 months from the date of purchase, and Creation Networks supports system design questions and after-sale service.
