Krix Loudspeakers UCX-218 – a subwoofer with bass from 10 Hz!

22.05.2025 08:13 | ~1 minute read

Sales of the infrasonic passive subwoofer Krix Loudspeakers UCX-218 have begun — the most powerful model from the Australian company. The model uses a pair of 18-inch woofers with a long diffuser stroke. The woofers are located in the housing opposite each other, which compensates for mechanical vibrations and provides a clean, neutral bass sound. The operating range of the Krix UCX-218 subwoofer starts from a record 10 Hz.

You should also take into account the gain — to drive the model, you will need a power of 2 x 1500 - 3000 Watts into 4 Ohms or 1 x 3000 - 6000 Watts into 2 Ohms (parallel). The Krix UCX-218 subwoofer also features flexible installation - it can be placed both vertically and horizontally, including installations with multiple subwoofers. The new product weighs 91 kg and is supplied as three modules.
