Award-winning frequency response with exceptional bass feedback. Exchangable NOAH Modules customize bass response while providing sublime low-end tonality and rumble. Precisely tuned pressure valves prevent ear fatigue without any compromise on sound quality and isolation. Customize your hearing experience with the built-in vocal boost switch for a total of 4* expertly-tuned frequency curves. Grand Maestro is the ultimate end-game monitor for anyone looking to take their music experience to the highest level.


(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 hearted.


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 all our IEMs when plugged into any device - Be it your mic-pack, mixer board, phone or dedicated DAP.


Meticulously engineered, the chamber utilizes cutting-edge acoustics to amplify low-frequency vibrations - Setting the benchmark for deep, captivating Bass response.


Detachable Bass Chamber Modules allow you to customize your Subwoofer Slam while retaining the breathability of our custom-built DD. Black 'Power' Modules concentrates Sub-bass power for more Slam. Blue 'Control' Modules controls the Sub-bass response for more Rumble.


Enhance the clarity of vocals in your audio content with a flick of a switch. Whether you're listening to music, podcasts, or watching videos, you'll hear every note and word with remarkable precision.


Upgrade your set with our Custom-made Gold-Plated Pure Silver Cable to enhance the Musicality and Headroom of your mixes. Package includes exchangeable 2.5/3.5/4.4 audio jacks for your choice of source.
