About this product.

Design

The SW18A extends the low end of select ED Series point source loudspeakers. Its 18 in driver has a moisture-resistant, glass-fiber-reinforced cone. A double centering spider keeps the 4 in voice coil centered even at high excursion.

The 15 mm phenolic birch plywood cabinet has a 35 mm pole socket for mounting two-way ED Series speakers above it. Recessed handles, polyurethane wheels, stacking feet and matching recesses aid transport and ground stacking.

Processing and amplifier

Processing runs on the CORE DSP platform designed by PROEL R&D, using a SHARC DSP. It works at 40-bit, 96 kHz floating point with 24-bit AD/DA converters. Dynamic range exceeds 110 dB.

PRONET software, on a CANBUS network, controls the whole system remotely. It handles EQ, delay and protection settings, and monitors amplifier status.

A DA Series Class D power module with a digitally controlled switch-mode power supply drives the system. Its variable switching frequency gives clear sound at every frequency, strong low-level dynamics and very low distortion at full power. Efficiency exceeds 90% in a compact, lightweight module.

The module delivers 2,000 W to the woofer. This power reserve handles high voltage peaks for strong dynamic performance.
