About this product.

Design

The SW18P extends the low end of select ED Series point source loudspeakers. It suits live music venues, nightclubs, bars, houses of worship and corporate A/V.

Driver

The high-power 18 in (460 mm) driver reaches up to 30 mm peak-to-peak excursion. A high-stiffness Double Silicon Spider keeps travel linear at high output. The high-strength (BL²/Re) motor uses an inner flux demodulating ring for symmetry and excursion control.

The 4 in (100 mm) copper voice coil is wound in two layers, inside and outside the former. This doubles the cooled surface and improves long-term thermal capacity. The cone is high-stiffness, glass-fiber-reinforced paper with an invisible water-repellent treatment.

Cabinet

The 15 mm phenolic birch plywood cabinet has an M20 pole mount socket for two-way ED Series speakers. Recessed handles, polyurethane wheels, stacking feet and recesses aid transport and stacking. Two Neutrik speakON NL4 connectors provide input and link.
