The Rumble-KU315, with its nominal rated power of 2000 W @ 4Ω, is the most powerful passive subwoofer in the Rumble series, the only in the series made of polyurea-coated birch plywood, and featuring a 15″ neodymium transducer in a shallow and relatively slim box. Like any other Rumble subwoofer, rather than having reflex openings, the KU315 features two more 15” passive radiators that make sure that the transducer excursion is as linear as possible with minimum residual noise and ensure the device remains completely sealed off from foreign objects. This feature, together with the quality of durable materials and the upgrade to the SpeakOn NL4 connector for this model, make the Rumble-KU315 resistant to tough weather conditions and suitable for outdoor installations.
A combination of extended frequency response with prodigious output and a discreet form factor make the KU315 the ideal solution for complex medium and large-format projects like clubs, lounges, theaters, cinemas, and auditoria. Measuring 123 x 45 x 25 cm (48.4 x 17.7 x 9.8 in) and weighing 40 kg (88.18 lb), the KU315 is available in elegant black or subtle white and can be customized in any RAL color, making it easy to blend in a variety of environments.
