Rumble module - Feel the Beat.
Rumble is the second hardware expansion module for the OP-Z. It's a built-in haptic subwoofer, using high-definition vibrotactile feedback and psychoacoustic technology, allowing you to feel your music.
When using Rumble you will feel like you're holding and listening to a deep sounding subwoofer. The frequency response 10 - 150hz is designed to maximise impact while minimising additional energy consumption.
It also features a silent metronome mode, great when performing live to always know exactly where the beat is.
