LA-12
Compact, high performance three-way line array systems
FEATURES Compact, high performance three-way bi-amplified line array element. High power - maximum SPL 125dB continuous, 131dB peak(single cabinet). Wide bandwidth - 45Hz ~ 18k Hz (single cabinet) One 12" LF speakers, horn and reflex loaded in a hybrid bass system, offer improved performance and extended low frequency response, - 99dB/w/m (single cabinet). Dual 6.5" mid frequency speakers coupled to a constant directivity horn using toroidal phase devices. Three 1" exit throat compression drivers mounted on vertically coupled waveguide with a constant directivity horn.
The
Fast, integral rigging system with variable splay angles.
Optional high-grade steel flying grid. Black powder coated perforated steel with waterproof foam.
LA12 is three-way line array system designed for medium to large scale sound reinforcement applications. The LA12 is a full range system and may be used without subwoofers in many applications. Where additional low frequency extension is required, La12 may be complemented by the Hps218 subwoofers.
The
three-way full range loudspeaker system consists of 1x12inch low frequency cone driver, 2x6.5inch mid frequency cone drivers and 3x1inch exit, 1.3inch voice coil compression drivers coupled to a special waveguide for HF reproduction.
The
cabinet is constructed from premium birch plywood and coated with a durable, textured black finish. A metal grille with waterproof foam protects the drivers.
Depending
APPLICATIONS Theatre sound reinforcement. Live sound reinforcement.
on the number of cabinets, flown or stacked, the vertical directivity can be controlled from 0¡ To 8¡, giving full freedom to the sound engineer. The horizontal dispersion remains constant at 100¡, Independently on the number of cabinets.
The
frequency response of a single La12 is form 45Hz to 18kHz. The maximum SPL is 125dB continuous & 131dB peak.
