The Dayton Audio BST-2 is a 35 W tactile bass shaker (transducer) at 4 ohms with a 10-80 Hz response for sim racing, gaming and home cinema that turns your seat or cockpit into a surface that vibrates with the deepest bass.
Unlike a speaker, the BST-2 doesn't reproduce audible sound: it captures frequencies too low to hear and converts them into physical vibration, so you feel the explosion, the thunder or the engine without turning up the volume. Its cast aluminium housing dissipates heat for a long service life, the dual suspension keeps a linear motion free of noise, and it includes 24" (61 cm) attached leads and a foam gasket for quick, rattle-free mounting on any flat surface.

Compatibility
The BST-2 needs a bass shaker amplifier that supports 4 ohms; Dayton Audio recommends the SA70 for one or two units, the APA150 for four (series-parallel at 4 ohms) and the BSA-200 for six (series-parallel at 6 ohms). In sim racing it's driven from PC with SimHub or other telemetry software, and it also adds impact to home cinema and gaming. Apply a low-pass filter at 80 Hz or below to remove unwanted high frequencies. You can add the dedicated BST-2 mounting kit for a clean fit.
Dayton Audio BST-2 FAQ
Is the Dayton Audio BST-2 good for sim racing?
Yes. Mounted under the seat or on the cockpit frame, the BST-2 reproduces the engine, bumps and track impacts as physical vibration. It's driven from PC with SimHub to sync the effects with your telemetry.
What's the difference between the BST-2 and the BST-1?
The BST-1 delivers 50 W RMS and the BST-2 35 W RMS. The BST-2 stands out for its dual suspension, its 24" attached leads and its foam gasket, designed for quick, quiet mounting on any flat surface.
Do I need an amplifier for the BST-2?
Yes. The BST-2 is powered by a bass shaker amplifier that supports 4 ohms. Dayton Audio recommends the SA70 for one or two units, the APA150 for four and the BSA-200 for six.
How many BST-2s can I connect together?
Up to six with the right amplifier, wired in series-parallel to set the impedance. Always check in your amplifier's manual that it supports the final impedance.
Does the BST-2 make audible noise?
No. The BST-2 generates vibration, not sound, and its dual suspension avoids unwanted noise: you feel the bass without turning up the volume or disturbing the next room.
