FATfreq Tech

BASS CANNON™ (Patent Pending): Using proprietary dynamic woofers, bass chambers and acoustic filter networks, FATfreq was able to design the deepest bass ever recorded of over 20dB, concentrated below 200Hz with zero bleed. Not for the faint of heart.

NOAH MODULES: Customizable bass chamber technology that revolutionizes in-ear monitoring. Switch out your modules for personalized bass tonality and tuning while benefiting from the pressure relief valves which prevent ear pressure build-up. Experience personalized sound and ultimate comfort with Noah Modules. Built with BASS CANNON™.

LINEAR IMPEDANCE: FATfreq uses proprietary circuits to correct the non-linear impedances of multi-driver systems. The different output impedances across all your devices cause frequency response to vary. Having this tech ensures consistency in frequency response for the entire FATfreq IEM lineup.
