The design of this subwoofer is absolutely unique and has been made by our R&D department to ensure an exceptional sensitivity.

Thank to this specific principle, MTSub218 MKII has a more powerful throw than competitors.

The passive version can be managed with Lake, XTA, Matrix Media or Q-Sys but we recommend Powersoft amplifiers with custom presets especially prepared for Audiofocus Mtsub218 MKII.

Plug & Play version offers to the user a full secured and easy to setup subwoofer. The perfect matching between Powersoft module and transducers gives high damping, punch and deep reproduction of the sound. The internal DSP treatment is managed with 4 clever preset including cardio mode.

For more customised needs a Fine tuning version is equipped with an RS485 interface module working with Armonia software for remote control and monitoring Powersoft amplifiers.
Armonia constitutes series of new and unique tools for system designers and sound engineers who want to significantly boost sonic performance and system reliability.
