Overview

The Rumble-KU44 line array element is an extremely compact, array-able subwoofer with a frequency range of 50 Hz to 150Hz and is comprised of two 4” neodymium transducers and two 4” passive radiators engineered for maximum linear excursion and minimum residual noise.

For easier use and integration with all Kommander amplifiers, the KU44 allows the user to choose between two different values of impedance (8/32 Ω). At 32 Ω, as many as eight KU44 units can be powered off a single Kommander amplifier channel.

Features

Visually Discreet
For architectural reasons, a visually discreet audio system may be required to integrate seamlessly with the layout without compromising sound quality.

Lightweight
We created a portfolio complete with lightweight products that are easy to transportation and quick to setup optimizing logistics, space, labor costs and time.

Premium Finishes
Similar to high-end fashion accessories and jewelry, our products undergo the most advanced coating process for a more beautiful and lustrous look.

Color Customizable
We have the ability to customize your project by color matching your system to any RAL code to help you to better integrate the speakers into a wide variety of venues.

Weather Resistant
We utilize the most durable and resistant materials when developing our products to protect and conserve the system regardless of the elements, rendering a K-array installation reliable and long-lasting.
