Technology
Developed by FATfreq in Singapore
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.
Care Tips
Removing 2pin Cables
When removing 2-pin cables during cable rolling, please ensure you pull the cables straight out in a careful, fully parallel motion. Avoid any twisting or angling, as this can cause damage to the IEM. Our recessed 2-pin design prevents loose connections and protects the actual 2-pin conductors from bending or breaking, but improper removal may lead to breakage. Always take care to protect your IEMs during cable changes.
