Nemesis Audio NA-18F is an 18-inch high-performance subwoofer built for serious bass in premium car-audio installations, pairing a die-cast aluminum basket with a 266 oz magnet and a 3-inch two-layer flat-winding voice coil for high-output, linear bass.

• Woofer Size: 18 inches — delivers deep, authoritative low-end extension with substantial cone area for high SPL in large enclosures.
• Basket: Die-cast aluminum basket — rigid frame minimizes cone flex and maintains alignment under demanding motion.
• Cone: Non-Pressed paper cone — lightweight construction supports fast transient response and accurate bass.
• Surround: Foam surround — durable, compliant edge control that preserves travel and seal across temperature ranges.
• Voice Coil: 3-inch, 2-layer flat-winding — large-diameter coil improves heat dissipation and supports high excursion reliability.
• Magnet: 266 oz high-efficiency magnet — substantial motor strength for strong control and low distortion at high output.
• Spider: Nomex spider with tinsel-woven leads — rigid support with robust lead management for longevity under heavy use.
• Impedance: Dual 4-ohm impedance — provides flexible wiring options to match amplifiers and achieve desired load.
• RMS Power Handling: 1200W RMS — continuous power handling suitable for demanding systems when paired with a capable amplifier.

In real-world builds, the NA-18F pairs a powerful motor with a lightweight, rigid sonic body to deliver controlled bass at high volumes. The dual 4-ohm voice coils and substantial magnet enable versatile amplifier matching, while the Nomex spider and tinsel leads practice reliability under dynamic movement and prolonged sessions.
