Advert Description
Great sounding Bass bin. Been used but still sound great. Pick up from the Leigh-on-Sea area only as it is heavy, although it does have casters.
SWA1801
? The SWA1801 is an 18-inch high output, active sub
woofer system. It features a newly designed high-precision 18-inch transducer combined with application-specific
amplifier technology. The system is composed of a single,
compact subwoofer cabinet with built-in control and amplifier electronics.
? The transducer used in the SWA1801 system features
an RCF Precision 4-inch, inside/outside wound voice
coil that offers extreme power handling capabilities. The
magnetic assembly used features advancements in coil
venting, composite polymide former construction, and
structural cooling that provide lower temperature rise and
substantially improved power compression characteristics.
? The amplifier found in the SWA1801 cabinet is an
example of application-specific amplifier design that can
be exercised when designing active speaker systems. The
system uses a proprietary high-efficiency, high-current
amplifier designed to provide high current levels at all
levels of operation. Having access to high current levels,
no matter what the power output, is absolutely critical
in achieving precise, total control of the woofer mass.
This control is responsible for lowering audible distortion artifacts and providing aggressive attack through the
operating band pass of the system. The amplifier, which is
mounted on a large, finned aluminum heat sink, is rated at
900 watts RMS continuous output.
? The cabinet is constructed using 18 mm thick multilayered birch plywood and finished in black splatter paint.
There is one handle on each side for efficient loading and
transport as well as a top, female pole mount fixture.
