The GEO M6B is a low and mid-frequency partner module to the GEO M620, for applications which demand more powerful reinforcement, such as live music. With one 6.5 inch 8 long-excursion driver, the M6B weighs just 7.6kgs and shares the same physical footprint as the M620 allowing the cabinets to be arrayed together in the same column. Featuring a flare-shaped port tube to increase low frequency efficiency and linearity at high power, the M6B offers a usable range @-6dB of 70Hz-1kHz.
