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!
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.

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 compression chamber optimizes the horn's output, allowing the the subwoofer to achieve amazing and unprecedented output levels.
