USER MANUAL
SW18A
active subwoofer
KEY FEATURES
• High power compact subwoofer
• Bass-reflex Direct Radiating Subwoofer
• Small size for a good output-toweight ratio
• 96KHz / 40 bit floating point CORE processing with PRONET remote control
• Digitally controlled Class D amplifier module with SMPS
INTRODUCTION
The SW18A is a high power compact subwoofer designed to partner ED series point
source loudspeakers for fixed installations in discotheques, nightclubs and bars, and
live music clubs, and for portable corporate audio-visual applications. 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, flush handles,
and heavy duty wheels to enable easy handling and transportation.
The SW18A subwoofer system is equipped with a high power 18” (460mm)
transducer capable of long excursion (up to 30mm peak-to-peak), controlled by
high stiffness Double Silicon Spider as centering suspension and by heavy duty
surround. The motor structure features high strength (BL²/Re) with optimized
symmetry and excursion controlled by Inner Flux Demodulating Ring. The robust
copper 100mm (4”) voice coil is wounded in two different 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-stiffness glass fiber reinforced paper, featuring also invisible
water repellent treatment.
The powered SW18A features an integrated 2000 watt class D amplifier module
that provides convenience and simplicity of connection for portable sound
reinforcement applications, and also for fixed installations in discotheques and
live music clubs. 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 applications, while its small size enables it to be easily
fitted into tight venue spaces.
