Product Overview: Audio Ace's Extreme SQ/SPL Hybrid Subwoofer

The Audio Ace Rebellion 18" D1 is engineered for the highest demands, built with the goal of achieving a perfect balance of high Sound Quality (SQ) and high Sound Pressure Level (SPL). Rated at a phenomenal 4,000W RMS, the Rebellion features a strong 498 oz motor structure and a low Free Air Resonance (Fs) of 28 Hz, allowing it to sound great across a wide range of music. With a 4-inch voice coil and a substantial linear excursion (Xmax) of 25mm each way, this subwoofer is versatile enough for either competition or daily driving at EXTREME sound levels. The Dual 1 Ohm impedance allows for a final parallel load of 0.5 Ohms.
