Compact tactile punch for serious sim racing feedback.
The Xcite XBS50-4 is a 4 ohm tactile bass shaker built for high-resolution haptic feedback where space is limited. With a 35 mm ultra-slim profile, 50W RMS handling, 250W long-term max power and up to 155 N peak force, it is made to add physical detail to a cockpit without needing a bulky transducer under the seat.



Feel more than one generic rumble note.
A good tactile setup should separate detail: engine vibration, gear shifts, road texture, kerbs, impacts, ABS or traction events. The XBS50-4 is designed for fast, controlled low-frequency feedback, making it a strong choice for sim racing rigs, haptic seats and compact platforms where every millimeter matters.
Use it under the seat base, behind the backrest or on a rigid cockpit plate for body feedback.
Multiple units can be used to split effects between seat base, back, pedals or rig zones.
17 Hz to 1 kHz rated range gives headroom for both low impact and more detailed texture.
High force-per-watt sensitivity helps it deliver strong response without needing a huge amplifier.

Ultra-slim, without giving up excursion.
Most flat tactile transducers become thin by sacrificing travel. Xcite’s SpiderCore design integrates the suspension into the motor core, helping the XBS50-4 stay only 35 mm high while still allowing ±9 mm mechanical excursion. The result is a compact shaker that can fit in tighter cockpit spaces while still producing a physical hit.
Low-profile body for tight seat, platform and cockpit installations.
Mechanical excursion for real tactile movement, not just small vibration.
Built for dust, moisture and demanding environments.
Ultra-light motor structure for fast, responsive impact.
Mount it firmly, then tune the effect around your rig.
Like any tactile transducer, the XBS50-4 performs best when it is mechanically coupled to a rigid surface. It is secured with four screws and connected through spring terminals. For sim racing, a solid seat plate, backrest plate, pedal plate or aluminum-profile mounting solution will transfer feedback more cleanly than soft padding or loose brackets.
Mount to a firm seat, plate or cockpit structure so vibration transfers into the driver.
Use an amplifier that can safely drive 4 ohm loads and match the number of shakers to the channel rating.
Around 100 Hz is a strong starting point for impact, with up to 150 Hz when you want more detail.
Small body, real power requirements.
The XBS50-4 is a 4 ohm bass shaker with 50W RMS handling and 250W long-term max power. A suitable amplifier should be stable at the final impedance of your wiring and powerful enough to control the shaker cleanly. For multi-shaker rigs, plan channels and impedance before connecting everything together.

Is it only for sim racing?
No. It can also be used for home cinema seats, haptic platforms, gaming setups, VR rigs or other tactile feedback projects where a compact bass shaker is useful.
How many should I use in a cockpit?
Two units per seat is a strong setup for seat base and upper back feedback. Advanced builds can use more units for spatial layering across different rig zones.
