GK-218 is a single 18-inch high-efficiency subwoofer, which can provide a frequency range of 30 Hz - 200 Hz. It is designed to be used with full-range loudspeakers from the Fane Pro Audio GK series or other full-range models from the FPA family.
Powered by custom FANE 18-inch woofers with a 4-inch (101.6mm) high-power voice coil. GK-218 is designed to be dynamic with minimal port turbulence at high excursions. The large port design enhances the output efficiency of the system, increasing the output of ultra-low frequencies and reduction of non-linear distortion to produce 138dB SPL.
There are two built-in wooden handles on each side of the GK-218 enclosure to help stacking or ease of movement. Four rubber foot pads are installed at the bottom of the box and there are 4-foot pad recesses on the top side, which are convenient for ultra-low array stacking.
The cabinet is constructed from 18mm birch plywood and finished with a wear-resistant, black, water-based paint and finished with a black, perforated iron grille backed with an acoustically transparent wadding.
