Read moreThe Thunder-KS1 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 KS1 I provides deep and dynamic bass while maintaining precision and clarity across the low-frequency range.
At its core, the system features a 12" neodymium magnet woofer, delivering extended bass performance. Built with a polyurea-coated birch plywood enclosure and no bass reflex, the KS1 I combines durability with portability and controlled emission, measuring 500 × 350 × 440 mm and weighing 18 kg.
Collapse textLow frequencies have always been one of the most challenging aspects of system design. Their natural omnidirectional behavior makes control difficult, often resulting in unwanted energy on stage and a less defined sound.
The combination of integrated cardioid technology and advanced simulation environments allows low-frequency behavior to be predicted and shaped with precision.
This approach enables controlled directivity, reduced rear radiation, and a cleaner, more consistent acoustic experience across any application.
The Thunder Series subs are built with a choice of Finnish birch plywood so it lightweight and incredibly resistant, making it the perfect speaker for audio rentals.The new polyurea paint and the cataphoresis treatment for the front grill, further treated with powder coating, also give greater resistance to the harsh weather environments often experienced on the road.
The details can really make the difference, the side handles are elegantly integrated into the speaker body beautifully crafted for comfort. The M20 threaded flange on the top which is essential for combining with the speaker stands and pins of the Pinnacle and Axle systems, is made for steadiness with internal strong tubular brackets to give more stability.
In their active version, the Thunders are more than just subwoofers. They include powerful 4-ch class D amplifiers fully managed by sophisticated integrated DSP processors.
This combination allows the electronics of a Thunder to deliver not only the power signal to the subwoofer itself, but offers up to three additional channels of amplification and processing, thus becoming a complete control unit that allows you to drive an entire stereo system using only one active unit. Questo si trasforma anche in un grande vantaggio economico.
The Thunder series is offered in black or elegant white finish and can be customized to match any RAL code to better integrate them in a wide variety of venues.
Thunder subwoofers are manufactured to achieve exacting standards and are subject to rigorous quality control system in Italy.
