The STX Audio STXW12D4 is a high-performance 12-inch pro audio subwoofer crafted for demanding car audio applications. With its impressive 3000W peak power handling, this subwoofer is tailored for enthusiasts who seek robust and impactful bass. At the heart of the STXW12D4 lies a high-excursion 75.5mm voice coil, designed for extended linear movement, allowing it to displace significant air volume while keeping distortion to a minimum, even during intense playback at high power levels. The dual 4-ohm voice coil configuration offers exceptional wiring flexibility, enabling optimal impedance matching with your amplifier, whether you prefer a 2-ohm parallel setup for maximum power or an 8-ohm series configuration for higher impedance needs. The dual magnet motor structure, featuring two φ190mm x 25mm magnets, ensures a strong and consistent magnetic field, which contributes to tight transient responses and well-defined bass. With a frequency range spanning from 50Hz to 2KHz and a sensitivity rating of 93dB ± 2dB at 1W/1m, the STXW12D4 excels in producing powerful sound output relative to its power consumption. Its 324mm (12-inch) nominal diameter design is optimized for both sealed and ported enclosures, making it a versatile choice for any serious car audio setup.
