STX 12 Reference

Subwoofer chassis for enclosure installation

The STX 12 Reference is a powerful subwoofer for enclosed and bass reflex housings. The multi-layer pressed, air-dried paper cone exhibits a perfect combination of robustness and weight, while the high performance 135oz double magnet provides the necessary drive. The 3" 4-layer high performance voice coil is wound with exclusive Japanese TOTOKU wire. Maximum power handling capacity is ensured by a double seam between the cone and surround, as well as the diamond cut aluminium basket and additional voice coil ventilation.
