Description

Product Overview

Bring deep bass and high output to your car audio system with the Audio Ace Rebellion Series 18" Dual 1 Ohm subwoofer. Its 4,000 RMS rating, low Fs, and 4-inch voice coil are designed for demanding playback.

Key Features & Benefits

  • 18-inch subwoofer: Its large effective piston area helps move air for stronger bass output.
  • Dual 1 Ohm impedance: Gives you wiring options when planning your amplifier load.
  • 4,000 RMS power handling: Supports high-power system designs with a capable amplifier and proper cooling.
  • Low Fs of 28: Contributes to deeper bass extension.
  • 25 Xmax: Defines the cone’s maximum linear excursion before distortion.

Technical Specifications

Specification Value and detail
Impedance Dual 1 Ohm — provides flexible wiring options and strong current delivery for high-demand amps.
RMS Power Handling 4,000 RMS — continuous power the driver can handle with proper cooling and a capable amplifier.
Fs 28 — 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.

Why Choose This Product?

The Rebellion Series combines substantial power handling with a low Fs and strong motor characteristics. That mix is intended for builds pursuing both high output and musical playback, including daily-driver systems where elevated sound levels are a priority.

Installation & Compatibility Notes

Plan your amplifier load around the subwoofer’s dual 1 Ohm impedance and rated power handling. The source does not specify enclosure dimensions or vehicle fitment, so confirm those requirements for your installation before choosing a setup.

Recommended Monoblock Amplifiers

Power-matched options for one subwoofer or one complete loaded enclosure. We aim to include same-brand choices when their ratings qualify.

Loading amplifier suggestions…

Suggestions use 75–125% of the subwoofer’s RMS rating at the wiring load shown. Check wiring, enclosure needs, electrical capacity and installation space. Set gain and filters correctly to avoid overpowering the subwoofer. Buying more than one subwoofer changes the match.
