Nemesis Audio NA-33T 33" 10,000W RMS Subwoofer DVC 1-Ohm

The Nemesis Audio NA-33T 33" 10,000W RMS Subwoofer is a competition-grade, wall-shaking, record-breaking SPL weapon. A 33" cone diameter, 6" flat wire voice coil, 70mm Xmax, 30.1 Tesla·m motor strength, and 10,000W RMS power handling — this is not a daily driver subwoofer. This is a purpose-built SPL competition driver engineered to move more air, hit lower, and hit harder than anything in a standard enclosure. Klippel® optimized from the ground up for maximum linear excursion and minimum distortion at extreme output levels.

The NA-33T is built around a Klippel® optimized motor structure — Klippel laser measurement and optimization ensures the motor, spider, and surround work together for maximum linear excursion with minimum distortion across the full stroke range. The fiber-reinforced paper cone provides the ideal balance of stiffness and mass at this scale — rigid enough to maintain pistonic motion at 70mm Xmax, light enough to respond accurately to the motor's 30.1 T·m force. The 6" (160mm) flat wire voice coil maximizes conductor packing density in the gap for maximum motor efficiency and thermal capacity at 10,000W RMS continuous. The high-roll sandwich surround and progressive 5-layer spider work together to control cone motion across the full 70mm Xmax stroke — keeping the voice coil centered and the cone moving linearly even at maximum excursion. The massive aluminum cast basket provides the rigid, thermally conductive foundation the motor structure demands at this power level. Dual 1-ohm voice coils wire to 0.5 ohms (parallel) or 2 ohms (series) for maximum amplifier compatibility in competition builds. Fs is 24.42Hz — this sub is tuned for infrasonic output. SPL sensitivity is 94dB/m. Includes 10mm² / 7 AWG connection cable (4.92 ft).

The NA-33T is a competition SPL subwoofer — it requires a purpose-built enclosure, a high-current amplifier capable of 10,000W RMS at 0.5 or 2 ohms, and a vehicle electrical system built to support the load.

Why Choose the Nemesis Audio NA-33T?

• 33" Cone Diameter: Massive cone area for maximum air displacement and SPL output — one of the largest production subwoofers available.
• Klippel® Optimized Motor: Laser-measured and optimized for maximum linear excursion and minimum distortion at extreme output levels — not just spec'd, but engineered.
• 6" Flat Wire Voice Coil: Maximum conductor packing density in the gap for peak motor efficiency and thermal capacity at 10,000W RMS continuous.
• 70mm Xmax: 2.76" of linear excursion — extraordinary stroke for a production subwoofer, enabling deep infrasonic output at competition SPL levels.
• 30.1 T·m Motor Strength: Exceptional BL product for a driver of this size — strong, controlled motor force across the full excursion range.
• 10,000W RMS Power Handling: Built for the highest-output competition amplifiers on the market — no thermal compression at rated power.
• Progressive 5-Layer Spider: Multi-layer spider design controls cone motion across the full 70mm stroke — keeping the voice coil centered at maximum excursion.
• Dual 1-Ohm Voice Coils: Wire to 0.5 ohms (parallel) or 2 ohms (series) for maximum amplifier compatibility in competition builds.

System & Installation Requirements

The NA-33T is a competition SPL subwoofer that requires a complete system build to operate correctly. Amplifier: a high-current mono amplifier rated 8,000–10,000W RMS at 0.5 or 2 ohms is required — contact us at Trinity Car Audio for specific amplifier recommendations. Enclosure: a purpose-built bandpass or ported enclosure designed specifically for the NA-33T's T/S parameters is required — do not attempt to use a generic enclosure. Electrical: a high-output alternator, multiple AGM or lithium batteries, and 0-gauge or larger power and ground wiring are required to support 10,000W RMS continuous draw. Contact us at Trinity Car Audio before ordering for a complete system consultation.

Frequently Asked Questions

Q: What amplifier do I need for the NA-33T?
A: A high-current mono amplifier rated 8,000–10,000W RMS at 0.5 ohms (coils in parallel) or 2 ohms (coils in series) is required. This is a competition-grade build — contact us at Trinity Car Audio for specific amplifier recommendations and a complete system consultation before ordering.

Q: What enclosure does the NA-33T require?
A: The NA-33T requires a purpose-built enclosure designed specifically for its T/S parameters (Fs 24.42Hz, Vas 534L, Qts 0.513). A bandpass or large ported enclosure is typical for competition SPL builds at this scale. Do not use a generic enclosure — contact us at Trinity Car Audio for enclosure design guidance.

Q: How do I wire the Dual 1-Ohm voice coils?
A: Wire the two 1-ohm coils in parallel for a 0.5-ohm final impedance (maximum power output from a high-current amp), or in series for a 2-ohm final impedance (cleaner operation with amps rated at 2 ohms). Contact us at Trinity Car Audio to confirm the right wiring configuration for your specific amplifier.

Q: What electrical upgrades do I need for the NA-33T?
A: A 10,000W RMS system requires a high-output alternator (250A+), multiple AGM or lithium batteries, and 0-gauge or larger power and ground wiring throughout. A Big 3 electrical upgrade is the minimum starting point. Contact us at Trinity Car Audio for a complete electrical system consultation.
