A really great sounding Makie subwoofer that will add real depth to any PA system. Really needs collection because of size but could arrange for courier. Would also be willing to meet halfway for collection with in reason.Manual

SWA1501
The SWA1501 is a 15-inch high-output, active subwoof
–
er system. It features a high-precision 15-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 SWA1501 system features a
3-inch voice coil that offers extreme power handling capa
–
bilities. The magnetic assembly used features advance
–
ments in coil venting and structural cooling that provide
lower temperature rise and substantially improved power
compression characteristics.
The amplifier found in the SWA1501 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 distor
–
tion 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
500 watts rms continuous output.
The SWA1501 features a sophisticated on board con
–
trol system, allowing for flexible integration with active or
passive full range or mid/high speaker systems. The input
panel accepts a line-level input signal and has LOOP OUT
connectors for signal routing to other devices. It also has
HIGH PASS out connectors for connection to active full range
speakers or amplifiers powering passive full range speakers.
All signal routing is through XLR connectors in L+R stereo
or mono. There is a phase selection switch and a recessed
level control. The system features thermal protection for the
power supply and amplifier and also incorporates rms limit
–
ing protection for the amplifier stage that limits the amount
of long-term power delivered to the transducer.
The cabinet is constructed using 18 mm thick multi-
layered 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.
