🧠 Advanced Motor & Cooling Design
The Level 3 features a 2.5mm aluminum shorting ring (demodulation ring) that:
-
Reduces inductance
-
Lowers distortion
-
Reduces power compression

Pulls heat from the voice coil windings

Combined with direct-to-coil venting, airflow cycles across the coil and aluminum ring simultaneously — improving cooling under heavy load.
