Dynamic Chamber

FATfreq's new acoustic system features advanced acoustic networks that manage sound wave propagation for optimal clarity and precision. Specialized bass chambers optimize airflow for enhanced tonality and deeper bass.

Bass Boost Adapter

Designed to enhance your listening experience by delivering an additional boost to the sub-bass frequencies. Carefully crafted with high-quality components, including pure silver wiring, this adapter provides a ~10dB increase in bass response under 150Hz. Perfect for those seeking deeper, more powerful bass without compromising clarity or sound quality.

Bass Cannon™

(Patent Pending) Using proprietary dynamic woofers, bass chambers and acoustic damping networks, FATfreq was able to design the deepest bass ever recorded of over 30dB, expertly controlled below 150Hz with zero mid-range bleed. A FATfreq innovation pioneered and perfected for sheer bass power.

Sonar La Trompa™

Inspired by the anatomy of the traditional french horn, FATfreq uses exponential horn curvature for gain control and to improve treble tonality via acoustics. Providing you with Smooth, natural sounding highs, grounded by a nice timbre in the mid and low frequencies.

PhaseAlign

The absence of a DSP in IEMs means that we have to match the phase of multi-way systems via Acoustic delay. Using proprietary structures, we were able to align the low, mid and high frequencies such that they reach your eardrum in a coherent manner. Giving you the sound accuracy and resolution demanded on stage and studio.
