NEXO STM M28 8-inch 2-Way Loudspeaker Module, Installation Version, Black

The NEXO STM M28 is a two-way, injection-moulded loudspeaker module designed as part of the NEXO STM system, combining 2x 8" LF Neodymium drivers with 2x HF compression drivers using Ketone Polymer diaphragms. This 90° Installation version offers configurable 90°-120° horizontal dispersion and 0°-15° vertical splay for flexible coverage in permanent installations.

With a frequency response of 65 Hz-19 kHz ±3dB, sensitivity of 106 dB and 141 dB peak SPL, the STM M28 delivers high-output performance suitable for venues requiring consistent, wide-area sound reinforcement. Nominal impedance is 8 Ω (6 Ω minimum) on both the LF and HF sections.

Connectivity is handled via 2x NLT4-MDV Speakon 4-pole connectors, while CompassRig and REDLock rigging hardware enable single-person flying and simplified array assembly. The cabinet features a black PU composite low-density coating for durability.
