- Unlock More From Every Bass Hit: BS-2 bass shaker turns low-frequency audio into physical vibration, while the custom-fit rubber mounting plate expands the effective contact area, bringing more of the structure into motion for broader, more complete tactile impact instead of vibration concentrated around one mounting point.
- Punchy 30W Tactile Performance: BS-2 uses a responsive drive system to follow changing bass with quick, distinct and controlled response, keeping tactile effects precise instead of loose or sluggish. Its aluminum housing aids heat dissipation, while a reliability-tested design supports stable performance through repeated vibration and extended use.
- Adapt the Feel to Your Setup: Different mounting structures call for different approaches. Standard mounting spreads tactile response across a broader area for a more unified sensation, while reverse mounting creates a more pronounced sense of impact, giving you more freedom to shape how low-frequency effects are felt.
- Skip the DIY Mounting Hassle: Purpose-built for BS-2, the flexible rubber plate combines pre-aligned holes, a recessed cable groove and included mounting hardware to cut down on measuring, cutting and trial-and-error setup, helping you build a cleaner, more installation-ready tactile setup with less prep.
- Bring More Impact to Every Experience: Add physical low-frequency feedback to home theater, sim racing, gaming, music, massage chairs or compatible vehicle seats. Pair BS-2 with the Douk Audio G100 or a suitable amplifier to make engine rumble, movie effects and deep bass feel like part of the experience.

Get More From Every Vibration
Tactile performance depends on how effectively the mounted structure transfers vibration. Direct mounting can confine it to a small area, while the plate brings more of the seat or panel into motion—without the hassle of building a DIY mounting board.
