Audio Ace Rebellion Series 18" Subwoofer Dual 1 Ohm

The Audio Ace Rebellion Series 18" Dual 1 Ohm subwoofer is built for car audio enthusiasts who demand both deep, controlled bass and high SPL capability. With a 4,000 RMS rating and a purposefully low Fs, it stays musical across a wide range of music while delivering extreme output when pushed hard.

• Impedance: Dual 1 Ohm — provides flexible wiring options and strong current delivery for high-demand amps.
• RMS Power Handling: 4,000 RMS — indicates the continuous power the driver can handle with proper cooling and a capable amplifier.
• Fs: 28 — a low resonant frequency contributing to deeper bass extension and cleaner low-end at high levels.
• Qes: 492 — electrical Q factor shaping how the cone responds to electrical drive and damping.
• Qms: 5.494 — mechanical Q factor affecting motion under excursion and transient response.
• Qts:.451 — overall Q, influencing enclosure tuning and control under dynamic bass.
• Sd: 1134.12 — effective piston area; larger Sd moves more air for stronger bass output.
• SPL: 89 — sensitivity rating that relates input power to output potential under test conditions.
• Re: 1+1 — DC resistance of the voice coil, used for amp loading calculations and impedance behavior.
• BL: 26.359 — motor strength factor; higher BL improves cone control at high excursions.
• Xmax: 25 — maximum linear excursion before distortion, defining how far the cone can travel for deep bass.»
• Voice Coil: 4 inch — coil size that supports heat dissipation and power handling at high output.
• Each Way Motor: 498 oz — magnet/motor assembly strength contributing to overall control and durability.
• D1: 4,000 RMS — reiterates the rated power handling capability tied to the driver’s design.

Benefits: In high-power builds, this 18" dual-1-ohm sub delivers deep, impactful bass with strong control, suitable for flagship installations or daily-driver systems where extreme sound levels are pursued. The combination of low Fs, high motor strength, and substantial voice-coil size supports sustained, demanding playback while maintaining mechanical stability and accurate transient response. Its flexible impedance pairing and substantial power handling make it a capable cornerstone for enthusiasts seeking both loudness and musical fidelity.
