🧠 Advanced Cooling & Motor Technology
The Level 4 now includes a 2.5mm aluminum shorting ring (demodulation ring) which:
-
Reduces inductance
-
Lowers distortion
-
Reduces power compression
-
Pulls heat from the coil windings
-
Acts as an internal heat sink
Combined with direct-to-coil venting, airflow cycles across the coil and aluminum shorting ring simultaneously — dramatically improving heat dissipation under load.
