Rumble-KU26

The Rumble-KU26 is an ultra-compact subwoofer that delivers exceptional bass performance while maintaining a discreet profile. It features one 6” neodymium transducer and one 6” passive radiator, engineered for maximum linear excursion and minimal residual noise. With a frequency range of 45 Hz to 150 Hz, the KU26 is the perfect low-end complement for K-array Lyzard, Vyper, Tornado, and Anakonda speakers.

Selectable Impedance & Seamless Integration

With a dual voice coil (16+16 Ω), the KU26 allows selectable impedance settings of 8Ω or 32Ω. At 32Ω, up to eight units can be powered by a single 4Ω amp channel. Utilizing dedicated presets, K-array Kommander amplifiers ensure a perfectly balanced setup when paired with any mid-high speaker in the K-array lineup.

Durable & Weather-Resistant

Built from stainless steel, the KU26 is highly resistant to harsh conditions, making it ideal for waterfront environments where conventional subwoofers would corrode. It is impervious to dust, sand, and water, ensuring long-term durability. The optional MARINE version provides enhanced protection against salt corrosion.

Compact & Versatile Design

With a compact footprint of 350 x 180 x 118 mm (13.8 x 7.1 x 4.6 in) and weighing only 5.9 kg (13.0 lb), the KU26 fits seamlessly into a variety of environments. It is available in standard black or white and can be customized in any RAL color or premium finishes such as brushed or polished steel, 24K gold, rose gold, and antique gold plating. This ensures aesthetic adaptability for a wide range of applications, including hotels, churches, restaurants, pubs, retail stores, and conferences.
