B-52 is the only manufacturer of
Dual 18" Active Folded Horn Subwoofers. The B-52 LX-1818A is built using
our award-winning digital amplification technology. The digital
amplifier produces unprecedented power levels, weighs just 6lbs, has a
built-in compressor / limiter, electronic crossover, is 93% efficient
and is perpetually cooled by a built-in high-performance fan.
DUAL ACTIVE 18" FOLDED HORN
SUBWOOFER
The B-52 LX-1818A is perfect for mobile DJs and touring sound
professionals that require tremendous bass output with the convenience
of an active system. It delivers more than 1200 watts of thundering bass
that will resonate all the way to the back of your venue. Precision
placed internal dividers allow each subwoofer to fire into the central
chamber without audible cancellation. Each subwoofer is housed in
separate compression chambers, resulting in kick-ass earth-shaking bass.
So, pump up the volume and feel what B-52's bass is made of!

THE DIGITAL DOMAIN
The lightweight digital amplifier is more than 93% efficient, draws less
power than conventional amplifiers and therefore generates less heat.
Less heat translates to longer device life, more efficient operation and
unparalleled reliability.
ONE AMP...TWO SUBS
The 1200-watt digital amplifier has the ability to power both B-52
18-200L transducers with maximum output and efficiency!
18" SUBWOOFER
The B-52 18-200L 18" subwoofer features a
cast-aluminum frame, 200 oz magnet structure, a bumped back plate for
greater excursion and a 4" dual-layered tempered-aluminum voice coil.
The voice coil is wound with 4 layers of 26-gauge copper wire, optimally
sized for this motor.
ALUMINUM HEAT SINK
The aluminum front panel heat sink dissipates heat in the subwoofer
compression chamber. This provides greater power handling, more overall
output and cooler long-term operation.
ELECTRICAL DRAW
The LX-1818A can be plugged in virtually anywhere without the risk of
popping a circuit breaker.
CABINET CONSTRUCTION
The LX-1818A cabinet is built for the abuse of the road. Each enclosure
is constructed with 3/4" plywood and includes metal carrying handles,
protective metal corners and 4" casters. A lifetime cabinet construction
warranty is provided.
INTERNAL COMPRESSION CHAMBER
The B-52 18" subwoofer's acoustic load is controlled by a specially
designed horn and compression chamber that minimizes the excursion of
the driver while maximizing the system's output. The optimally-sized
acoustic aperture of the compression chamber forms the throat of the
horn and helps to force air through the horn at an increased velocity
and pressure. The compression chamber optimizes the horn's output and
the acoustic impedance seen by the B-52 18-200L transducer. It is this
acoustic impedance transforming "phase-plug" design that enables the
LX-Series subwoofers to achieve amazing and unprecedented output levels.
18" SUBWOOFER INSIDE THE
COMPRESSION CHAMBER
The B-52 18-200L 18" subwoofer
features a cast-aluminum frame, 200 oz vented magnet structure, bumped
back-plate for greater excursion and 4" dual-layered tempered aluminum
voice coil former. The voice coil is wound with four layers of 26-gauge
copper wire, optimally sized for this motor.
As always, the
very impressive B-52 standard warranty:
Lifetime warranty on cabinet construction
Lifetime warranty on high-frequency devices
Five-year warranty on loudspeakers
Two-year warranty on amplifiers |
