“In sound quality and low frequency extension, the Earthquake MAGMAs excel leaving all other woofers behind” May 1999
CA&E. “With nearly 22mm of linear excursion (four times longer than other sub), and a hefty 3” 4-layer dual voice coil; the
MAGMAs make sealed box bass an octave lower than any other woofer.”
May 1999 CA&E.
