Rumble-KU210
Rumble-KU210 is a passive subwoofer from K-Array, built entirely from stainless steel with a slim 151 mm depth profile. A 10-inch neodymium woofer paired with a 10-inch passive radiator forms a fully sealed enclosure with no port, delivering bass extension from 40 Hz in installations where a low-profile, weather-resistant subwoofer is required.

Frequently asked questions
Why does the KU210 use a passive radiator instead of a reflex port?
The passive radiator replaces the port to keep the enclosure fully sealed, preventing dust, sand, and water ingress that would degrade a ported design over time, particularly in outdoor or coastal locations.
How many KU210 units can share one amplifier channel?
At the 16-ohm impedance setting, up to four KU210 units can be driven from a single amplifier channel rated at 4 ohms.
Are custom colours and finishes available?
Yes. The KU210X variant can be ordered in any RAL colour with a choice of brushed steel, polished steel, 24K gold, rose gold, or antique gold plating on both the box and grille.
