Earthquake FF6.5 Front Firing Subwoofer is an evolutionary step in the continued quest for superb bass performance. The FF series offers versatility, small footprint, and great looks all while staying surprisingly affordable. The powerful woofers used in the FF line have direct lineage to the lauded MiniMe subwoofers sporting massive excursion and high power handling. The amplifiers are refined descendants of the signature Sub-Series from Earthquake.

The third generation Earthquake FEA computer-modeled bass slot-port loading increases the output of the powerful woofer/amp combo. The new slot port provides more port volume than possible with traditional tubular port loading resulting in radically increased low frequency output. Since it is not a tubular device, it can bend at optimum angles reducing cabinet size making the subwoofer both powerful and aesthetic.
