HiFonics ZXS15D2

The HiFonics ZXS15D2 from the ZEUS STREET series is a powerful 38 cm (15-inch) subwoofer designed to deliver punchy, deep bass. With a power handling capacity of 600 watts RMS and a maximum of 1,200 watts, this subwoofer is suitable for both compact sealed enclosures and larger bass-reflex designs.

The specially coated, hand-made paper cone is attached to a double-stitched surround and is designed to withstand high mechanical stress. The powerful dual-magnet drive, featuring a pole piece bore and additional ventilation channels, ensures reliable heat dissipation. A 64-mm dual voice coil, each with an impedance of 2 ohms, allows for various connection options to compatible amplifiers.

The sturdy steel basket and the distinctive blue magnetic shield complete the design. Thanks to its well-thought-out construction, the ZXS15D2 offers a combination of high power handling, powerful low-end bass, and versatile applications.
