Welcome to Project Resonator

An Open-Source IEM Design Initiative
A love letter to the IEM/CIEM hobby.

This wiki will serves as a comprehensive guide for building your own custom in-ear monitors (IEMs). Whether you're a first-time DIYer or an experienced enthusiast, you'll find resources here to help you design, tune, and refine your own high-fidelity IEMs.
