INTRODUCTION
The SW18AP is a high power compact subwoofer designed to partner ED series
point source loudspeakers for xed installaons in discotheques, nightclubs and
bars, and live music clubs, and for portable corporate audio-visual applicaons. It
features a high excursion 4” voice coil, 18” driver equipped with a double centred
spider that maintains linear voice coil travel even at high output levels. The
phenolic birch plywood cabinet is equipped with pole mount socket, stacking feet,
ush handles, and heavy duty wheels to enable easy handling and transportaon.
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 and by heavy duty
surround. 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.
It will deliver punchy bass performance from a very compact cabinet, and thanks
to the integral pole mount socket partners well with any of the ED series of point
source loudspeakers in portable corporate audio-visual applicaons, while its small size enables it to be easily ed into ght venue spaces.
