G-218 is a high performance sub-bass system designed for large scale venues including touring and fixed installations. It features with two 18"(460mm) driver units with 18mm birch plywood enclosure, magnet structure and suspension engineered for maximum line ar excursion. Its two woofers are housed in band pass box with bass horn loading to deliver ultra powerful bass energy. The G-218 extends low-bass response and high efficiency, which make it an ideal partner for outdoor sound performance line array systems wherever high power, extended bass is required. G-218 is ideal for fixed sound installations such as discos, nightclubs, halls, conference centers and commercial events.
