Quad-Stack Ferrite Motor — Precision Machined from US Steel

Staged Aluminum Cooling + Solid Pole Design

To handle the heat of high-output performance, Ruthless Audio uses a solid pole structure with staged aluminum cooling, keeping the coil cool during extended demos or heavy daily use. This thermal management system ensures long-lasting durability and efficient performance even at full tilt.

Power loss? Not here. With 144-count lead wires double-sewn into the multi-spider suspension, you get max power delivery from the amplifier to the coil—every note hits hard and clean with zero drop-off.
