Lofelt and Teenage Engineering unveil Rumble, a silent haptic subwoofer module for the popular synthesizer and sequencer, OP-Z.

Rumble is the product of close collaboration between the acclaimed music/design house, Teenage Engineering and Lofelt. The module recreates the natural bass vibrations experienced on traditional acoustic instruments – but missing on modern music-making gear – and turns the OP-Z into the world’s first tactile audio synth. It features the one-of-a-kind Lofelt L5 wideband haptic actuator which reproduces frequencies from 150Hz all the way down to 10Hz in high-fidelity. Thanks to psychoacoustics, the human brain perceives these vibrations as deep, powerful bass. Rumble also adds another exclusive feature to OP-Z: a silent metronome for live performance.

Lofelt was originally founded to bring the physical dimension of music to digital instruments. Our founders, along with many of us on the Lofelt team, come from audio technology backgrounds. The first Lofelt product, the award-winning and unique Basslet wearable subwoofer, showcased our novel audio-haptic approach to deliver a richer, more powerful music experience.


Today, Lofelt has expanded its vision to designing the most remarkable haptic experiences for all our favorite devices. We have become the industry leader in audio-haptic technologies, driving a paradigm shift across several industries such as music, gaming, AR/VR/XR, medical and beyond. Lofelt innovative design tools and drive solutions put high-definition haptics in reach for any product.

With Rumble, we revisit our musical roots and, together with Teenage Engineering, once again push the boundaries of how people experience and create music by forging deeper connections between creators and their machines.

The Rumble is available for worldwide shipping in the teenage engineering online store starting today
