Know before you buy
The Xv3 features a significantly larger motor and incorporates the Zv5 voice coil. These upgrades provide increased linear Xmax, which translates to higher output, lower distortion, and a 500-watt increase in power handling.
The Xv3 is designed to deliver roughly 85% of the performance of the Zv5. It is an excellent choice if you want high-end output and power handling without stepping up to the Z-series price point.
The Xv3 is rated for 2500 Watts RMS. You should ensure your amplifier is capable of providing clean power within this range to get the most out of the subwoofer's design.
The choice between D1 (Dual 1-ohm) and D2 (Dual 2-ohm) depends on your amplifier's stable impedance and how you plan to wire your system. Choose the configuration that allows you to achieve the desired final impedance load for your specific amplifier.
This is a heavy-duty component weighing 75 pounds with a footprint of 20 by 20 by 20 inches. You will need a robust, custom-built enclosure that can support its weight and accommodate its significant displacement requirements.
The Xv3 is engineered for high output, but its design improvements specifically target reduced distortion, which helps it maintain clarity even at high volumes. It is a versatile choice for users who want a balance of raw power and clean, accurate bass reproduction.
