Nexo STM M46 Main Module

Injection-moulded high-power cabinet with innovative components for enhanced performance.

Nexo STM M46 Main Module

Flat-membrane drivers ensure completely even and full-range coverage over entire 90° horizontal dispersion. HF frequency range remains completely linear, using Kepton Polymer diaphragms that enhance tonal response and long throw.

System Operation
Electronic Controller The NEXO NXAMP4x4 presets are precisely matched to the STM Series cabinets and include sophisticated protection algorithms. Using STM Series cabinets without a properly connected NEXO NXAMP4x4 will result in poor sound quality and can damage components.
SubBass STM S118 extends system low frequency response down to 25Hz
Speaker Cabling 1-/1+: SUB - 2-/2+: LF – 3-/3+: LF-MF 4-/4+: HF
