12" 2-Way Powered Loudspeaker with CORE DSP

Overview

The ED120A delivers full-range sound and controlled dispersion from an easy-to-handle cabinet. It suits foreground sound reinforcement that needs quality sound, repeatable results and easy portability.

A 12" woofer pairs with a 1.4" compression driver, both with aluminum voice coils for low weight and good transient response. Each is driven by its own channel of a Class D amplifier.

The asymmetric vented enclosure works as front-of-house on a stand, pole-mounted on a subwoofer, or as a stage monitor at its 35° wedge angle. Add Axiom SW series subwoofers such as the SW18A for deeper bass.

Coverage and construction

The asymmetric HF pattern is 100° wide at the bottom of the horn for near-field coverage. It narrows to 60° at the top for focused far-field coverage. It covers a typical auditorium more accurately than a fixed-pattern horn.

Remove four screws to rotate the horn 90°. In monitor mode, the pattern then covers performers both near and far from the wedge. It also keeps ideal coverage when the cabinet is mounted horizontally.

The 15 mm phenolic birch plywood cabinet has a 35 mm pole mount, a recessed handle and M10 rigging points for optional mounting brackets. The KPTED120B wall bracket mounts it vertically or horizontally, with five steps of rotation for accurate aiming.

Processing and power

The CORE DSP platform, designed by Proel R&D, uses a SHARC DSP at 40-bit, 96 kHz floating-point resolution. Its 24-bit AD/DA converters deliver more than 110 dB of dynamic range.

CORE time-aligns the crossover for a linear phase response, and a constant power crossover gives a smooth LF-to-HF transition. PRONET software on CANBUS handles remote EQ, delay, protection and amplifier monitoring.

A DA Series Class D module with SMPS delivers 900 W to the woofer and 300 W to the compression driver. Efficiency is above 90%. Inputs and links use balanced XLR connectors with a ground lift switch, and a locking Neutrik powerCON links mains to more ED120A cabinets.
