Ruthless Audio Neo 18" D0.7 Subwoofer | 4500W RMS | 4" Voice Coil | Extreme SPL Performance

The Ruthless Audio Neo 18" D0.7 Subwoofer is the ultimate weapon for serious bassheads, demo builds, and SPL competitors. Featuring a massive 4” voice coil, earth-shaking 4500W RMS power handling, and an innovative 3-stage aluminum cooling and inductance reduction system, this subwoofer is built to crush expectations and dominate at full tilt.

Advanced 3-Stage Aluminum Cooling & Inductance Reduction System

Engineered for maximum performance and reliability, Ruthless Audio’s proprietary multi-stage cooling design dramatically improves heat dissipation and lowers inductance for tighter, cleaner bass at extreme power levels:

• Stage 1 – Machined Aluminum Pole Sleeve
  Acts as a thermal wick to pull heat away from the coil while beginning the process of inductance linearization and reduction.

• Stage 2 – Domed Aluminum Compression Cap
  Mated with the pole sleeve, this cap increases internal compression ratio for improved airflow and cooling, while further reducing inductance during heavy excursion.

• Stage 3 – Thick Finned Aluminum Extrusion
  Combines all previous elements with a high-mass finned heatsink, drastically improving thermal dissipation and delivering nearly 3x lower inductance than subs without this system.
