Exclusive 3-Stage Cooling & Inductance Management

Ruthless Audio’s innovative staged cooling design maximizes thermal control and inductance linearity — keeping your subwoofer cooler, cleaner, and louder longer.

• Stage 1: Machined Aluminum Pole Sleeve
  Efficiently wicks heat away from the voice coil while beginning inductance linearization for better motor control.

• Stage 2: Domed Aluminum Compression Cap
  Works with the pole sleeve to increase internal pressure, improve airflow for cooling, and reduce outstroke inductance under heavy excursion.

• Stage 3: Thick Finned Aluminum Extrusion
  This final stage brings it all together with a robust finned heatsink, delivering up to 3x reduction in inductance while massively boosting heat dissipation for full-power performance.

High-Performance Features:

• Available in 15" or 18" configurations

• 4” diameter, 4-layer flatwound voice coil in D0.7 or D1.7 ohm options
