Thunder-KS2 I

SUBWOOFER
Thunder-KS2 I

The Thunder-KS2 I is a high-performance ultra-light subwoofer line designed to deliver powerful and controlled low-frequency reinforcement for professional sound systems, live events, and installed audio applications. Despite its compact footprint, the KS2 I provides deeper and more authoritative bass while maintaining precision and clarity across the low-frequency range.

At its core, the system features an 18" neodymium magnet woofer, delivering extended bass performance down to 35 Hz. Built with a polyurea-coated birch plywood enclosure and no bass reflex, the KS2 I combines durability with portability and controlled emission, measuring 650 × 500 × 580 mm and weighing 34 kg.

The self-powered model integrates a Class D amplifier with DSP processing for advanced system control. It supports power outputs, analog and digital connectivity, and advanced networking. With built-in Web-App and K-framework3 software compatibility, it is accessible via dedicated K-Connect.

KS2 I is available in Black, White, and Custom RAL finishes, ideal for large-scale concerts, touring systems, and fixed installation applications.
