NEXO GEO M6B 6.5-inch Long-Excursion Bass Module, Custom Version

The NEXO GEO M6B is a low and mid-frequency bass module designed to partner with the GEO M620, adding reinforcement for applications that demand more power, such as live music and touring sound reinforcement.

Fitted with a single 6.5-inch 8Ω long-excursion driver, the M6B delivers a sensitivity of 94 dB and a maximum SPL of 125 dB, with a usable frequency response of 75Hz–120Hz ±3dB depending on preset. A flare-shaped port tube increases low-frequency efficiency and linearity at high power.

The M6B shares the same physical footprint as the GEO M620, allowing the two cabinets to be arrayed together in a single column. Signal connection is via 2x NL4 Speakon 4-pole connectors, and the enclosure is built from a lightweight polyurethane composite weighing just 7.6 kg. The module is TÜV certified and covered by a 2-year warranty.
