INTRODUCTION
The SW18P is a high-power compact subwoofer that provides extended low
frequency response for specic models in the ED series of high performance
point source loudspeakers. It is suitable for the use in live music venues,
nightclubs, barss houses of worship and for corporate and A/V applicaons.
The SW18P subwoofer system is equipped with a high power 18” (460mm)
transducer capable of long excursion (up to 30mm peak-to-peak), controlled
by high sness Double Silicon Spider as centering suspension that maintains
linear voice coil travel even at high output levels. The motor structure features
high strength (BL²/Re) with opmized symmetry and excursion controlled by
Inner Flux Demodulang Ring. The robust copper 100mm (4”) voice coil is
wounded in two dierent layers both outside and inside the coil support, then
doubling the coil surface exposed to air cooling and consequently improving the
long term thermal capacity of the loudspeaker. Cones are made of very high-
sness glass ber reinforced paper, featuring also invisible water repellent
treatment.
The 15mm phenolic birch plywood cabinet is provided with an M20 pole mount
socket to allow two-way ED series loudspeakers to be mounted above on a
speaker pole. Recessed handles are provided for easy liing and handing and
the included polyurethane wheels aid transportaon, while stacking feet and
matching recesses enable secure ground stacks. Two Neutrik® speakON™ NL4 connectors provide input and link connecons.
