THEY WILL MOVE YOU!
The B-52 SPF-18A and SPF-1818A
are designed for large permanent installation venues. They combine the
advantage of a long throw folded horn design with the power and
reliability of B-52's digital amplification. A 24 dB / octave electronic
crossover, compressor and hard limiter are built into the amplifier
allowing these subwoofers to easily patch into an existing system with
just pair of full-range XLR input cables! These cabinets are built using
13-ply Baltic birch, scratch-resistant paint, will withstand the abuse
of the road and can be used as dance platforms!
SPF-1818A
DUAL 18” ACTIVE FOLDED HORN SUBWOOFER
The B-52 SPF-1818A is perfect for club installations and large venue
applications that need tremendous bass output with all the conveniences
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 cancellation. The result is thunderous, tight, punchy
bass that can both heard and felt.

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.
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.
ELECTRICAL DRAW
B-52’S digital amplifier draw less than 12 amps of electricity at full
volume. So whether you’re throwing a party near a nuclear power plant,
or a house party with only a 15 amp breaker, the SPF-18A or SPF-1818A
can be plugged in virtually anywhere without the risk of popping a
circuit breaker.

CABINET
CONSTRUCTION
The SPF1818A and SPF-1818S cabinest are built for the abuse of the road
and to stand-up to the pounding club scene for installation. These subs
are constructed with 13-ply Baltic birch and are backed by our
unequalled warranty.
COMPRESSION
CHAMBER
The SPF-1818A and SPF-1818S cabinets house a compression chamber that
minimizes the excursion of the driver while maximizing the subwoofer’s
output. The optimally-sized acoustic aperture of the compression chamber
forms the throat of the horn and helps force air at an increased
velocity and pressure. The compression chamber optimizes the horn’s
output, allowing the the subwoofer to achieve amazing and unprecedented
output levels.
All
Architectural Series folded horn subwoofer cabinets feature 13-ply
Baltic birch construction, scratch resistant black or white paint finish
and a LIFETIME construction warranty.
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
