Xcite XBS25-4 is bass shaker designed for precise tactile feedback in sim racing and flightsim. Good alternative for Dayton Audio BST-2.The Xcite XBS25-4 does much more than its modest size. It can shake up an entire rig without Your wallet shaking. The transducer provides ±6 mm excursion, up to 93.1N peak force and 125 W long-term maximum power. Nobsound NS-01G PRO and Fosi Audio TB10A (with caution of TB10A output power) compatible.

Xcite XBS25-4 - questions and answers
1. What is the Xcite XBS25-4?
It is a passive tactile transducer that converts an audio signal into mechanical motion. When attached to a cockpit, seat or pedal deck, it makes audio effects or telemetry-generated cues physically perceptible.
2. Does the XBS25-4 connect directly to a computer?
No. The bass shaker requires an amplifier and speaker cable. The Fosi Audio TB10A uses an analogue RCA input, so the computer must provide the signal through a line output or separate sound card.
3. Which amplifier suits the XBS25-4?
We recommend the Fosi Audio TB10A. It supports a 4-ohm load, provides two channels and includes a 24 V / 4.5 A supply. The manufacturer states up to 2 x 100 W into 4 ohms, but actual continuous output depends on operating conditions.
4. Can the Fosi Audio TB10A drive two XBS25-4 units?
Yes. The simplest arrangement uses one 4-ohm shaker on the left channel and another on the right. Do not bridge the channels or connect their negative terminals together unless the manufacturer explicitly approves that mode.
5. Is the XBS25-4 rated at 25 W or 125 W?
The values refer to different tests. The datasheet specifies 25 W for the Rms Noise Test and 125 W as Long-term Max Power, both under IEC 60268-5. The 125 W figure should not be presented as a conventional RMS rating.
6. Where should the XBS25-4 be mounted?
Common positions include a pedal deck, the underside of a seat, the backrest and a wheel deck. The clearest effect comes from a rigid connection to the component that is intended to vibrate.
7. What is the mounting-hole pattern?
Four 3.3 mm holes are arranged on a 69 mm mounting diameter. The outer enclosure diameter is 75 mm and total height is 25 mm.
8. Does the XBS25-4 work with SimHub?
Yes, as part of an audio system. SimHub generates effects from telemetry, while a sound card and amplifier deliver them to the shaker. The XBS25-4 itself has no USB connection or built-in SimHub support.
9. What does IP66 mean?
The transducer enclosure is protected against dust and powerful water jets. This does not apply automatically to the rest of the system. The amplifier, cables, terminals and other electrical connections must be protected according to their own documentation.
10. Is one XBS25-4 enough?
One unit can provide local feedback through the pedals, seat or wheel deck. Two or more shakers make it possible to separate zones and effects, but require enough amplifier channels and correct impedance calculations.
| Component | Role in the system |
|---|---|
| Xcite XBS25-4 | Converts the amplifier signal into mechanical vibration. |
| Fosi Audio TB10A | Recommended 2-8-ohm amplifier with two channels and a 24 V / 4.5 A supply. The simplest arrangement uses one XBS25-4 per channel. |
| Audio output | The TB10A requires an analogue RCA signal from a line output or separate sound card. It has no USB connection or built-in audio interface. |
| Software | For example SimHub, which converts game telemetry into assigned audio effects. |
| Speaker cable | Connects the amplifier output to the bass shaker terminals. |
| Rigid mount | Transfers energy to the pedals, seat, wheel deck or another cockpit component. |
The offer covers one Xcite XBS25-4 unit. An amplifier, sound card, speaker cable and dedicated cockpit bracket must be selected separately. Confirm whether mounting screws are supplied with the stock received before publishing the package contents.
