Know before you buy
This pairing is required because the subwoofer's performance is factory-optimized to work specifically with the IPX 20:4's processing and power output. Using this dedicated amplifier ensures you achieve the intended sound quality, speaker protection, and system efficiency.
The X12I-128-B is designed for professional installation environments, but it is primarily intended for indoor use. If you are planning an outdoor installation, ensure the unit is protected from direct weather exposure to maintain its longevity and performance.
The dual 18-inch driver configuration is engineered to deliver deep, high-impact, and resonant bass. It is designed to provide substantial low-frequency extension and high output, making it ideal for large venues where high-fidelity sound reproduction is required.
As an install-specific subwoofer, it is built for robust, permanent mounting. You should consult the technical installation manual to ensure your mounting surface or enclosure structure can support the weight and handle the significant vibration generated by the dual 18-inch drivers.
No, this model is sold exclusively as a system with the Dynacord IPX 20:4. The system is calibrated as a matched pair, and the subwoofer is not intended to be driven by third-party amplifiers.
