Tender Specification: LX-10 ASX

Compact, Active 2-Way System Loudspeaker with Aluminium Housing for use in a Digital Audio Network System

Active system loudspeaker with integrated 2-channel digital amplifier and DSP technology, equipped with high quality 4“ / 0.75“ dome tweeter. Use of neodymium chassis and aluminium housing makes the loudspeaker very light in weight – approx. 1.3 kg. Ideally suited to dynamic speech and music reproduction, its elegant design also enables perfect optical integration.

With a capacity of up to 50 W, the speaker can generate a maximum SPL of 110 dB. The loudspeaker has a very precise dispersion of 100° x 100° (h x v) and a wide frequency range from 80 Hz to 20 kHz. Lightweight aluminium housing with rounded sides, black or white powder-coated. Optionally available in all RAL Classic colours and in Fohhn Texture Design. Other colour catalogues are also possible on request. To protect the loudspeaker chassis and electronics, the housing is fitted with a high grade, ball impact resistant, sound permeable front grille made from powder-coated galvanised steel. Two integrated M6 threaded inserts are designed to accommodate mounting brackets. CAAD simulation files for EASE are available.

Developed for dedicated use in a digital audio network system that includes active loudspeakers with integrated digital amplifiers and DSP technology, master modules and other system components.

Connections: Input via RJ-45 (Neutrik etherCON) for digital AES/EBU signals, control signals and power supply. Output via RJ-45 link out (Neutrik etherCON) enables serial connection (Daisy Chain) to other system components.
