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-1818S
DUAL 18" PASSIVE FOLDED HORN SUBWOOFER
The SPF-1818S delivers more than 2000 watts of thundering bass that will pound all the way to the back of your venue. While the subwoofers are connected in parallel, precision placed internal dividers allow each driver to fire into the central chamber without any cancellation. Each subwoofer is housed in a compression chamber, which allows the drivers to produce tight, punchy bass without over excursion of the voice coil.

B-52 18-200L 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.

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
