Feel the kerbs, shifts and engine load through your rig.
The Dayton Audio BST-1 is a 50W RMS tactile bass shaker made to turn low-frequency effects into physical vibration. Mounted to a sim racing seat, pedal plate or cockpit frame, it adds haptic feedback without needing to make the room louder like a traditional subwoofer.



More immersion without turning the volume up.
A bass shaker does not work like a normal speaker. Instead of filling the room with sound, it transfers low-frequency energy into the surface it is mounted to. In sim racing this can represent engine vibration, gear shifts, road texture, ABS activity or impacts when it is driven by compatible telemetry software and a suitable amplifier.
Mount under the seat or seat frame for the strongest body feedback.
Add a second shaker near pedals for brake lock-up, ABS or road texture effects.
Use a low-pass crossover around 80 Hz or lower to reduce unwanted high-frequency noise.
The shaker should sit firmly against a flat, rigid mounting surface for best transfer.

Install it like a mechanical part, not like a loose speaker.
For a clean sim rig installation, wire the shaker before final mounting and attach it with four suitable steel screws or bolts. The mounting point should be rigid enough to transmit vibration, while the shaker body should not rub against padding, carpet or loose material.
Under a seat, pedal plate or frame section, choose the area that transfers vibration best.
Speaker wire around 13 AWG / 2 x 2.5 mm2 is recommended for robust installations.
Use an amplifier that can safely drive 4 Ohm loads and keep power within the 50W RMS rating per shaker.
Need a cleaner way to attach the BST-1 to your rig?
For aluminum profile cockpits, we also make an OCRacing universal mounting plate for the Dayton BST-1. It gives the shaker a secure flat mounting surface and supports common 8040, 8020, 4040 and similar profile layouts with center or offset positioning options.

Correct impedance matters more than marketing watts.
One BST-1 is a 4 Ohm load. Multiple shakers can be wired in series, parallel or series-parallel, but the resulting impedance changes and the amplifier must be suitable for that load. Do not exceed 50W RMS per shaker.
4 Ohm load for a compatible stereo or bridged mono amplifier channel.
Raises total impedance to 8 Ohm.
Drops total impedance to 2 Ohm, only for amplifiers rated for it.
80 Hz or lower is recommended to keep tactile effects clean.
Compact 50W tactile transducer for rig and seat mounting.
Is it a subwoofer?
No. It is a tactile transducer. It is designed to be felt through a mounted surface, not used as a normal audible speaker.
How many do I need?
One under the seat is a strong starting point. Extra shakers can be added for pedals or separate rig zones if your amplifier and wiring support the load.
