“The art of progress is to preserve order amid change and to preserve change amid order.”
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.
LX-18A 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. A rock-solid
tilt-back metal bar handle for increased mobility. LX-Series subwoofers include
4” heavy-duty casters, providing ease of mobility and increased cabinet
longevity.
