ButtKicker BK-mini-LFE

Yes, the BK-mini-LFE is a passive tactile transducer, meaning it does not have a built-in amplifier. You will need an external power amplifier capable of driving a 4-ohm load to power it.

It is designed for single-seat setups like gaming chairs or home theater recliners. As long as your chair has a solid frame where you can securely mount the unit using screws, it should work, but avoid mounting it to cushions or fabric directly.

No, that is the primary benefit of this device. Because it transmits vibrations directly through the frame of your chair rather than moving air like a subwoofer, it provides a high-impact experience that is virtually silent to anyone not sitting in the chair.

A subwoofer moves air to create audible sound waves, while the BK-mini-LFE is a tactile transducer that physically shakes your seat to simulate the feeling of bass. It is designed to complement your subwoofer by adding a physical dimension to low-frequency effects that you feel in your body rather than just hear.

The internal thermal cutoff switch is a safety feature that automatically shuts down the unit if it begins to overheat from prolonged, high-intensity use. It protects the internal components from damage, ensuring the longevity of the transducer.

Not at all. The 9 Hz resonance frequency indicates the unit's natural capability to reproduce extremely low, infrasonic frequencies. It operates effectively across a range of 10-350 Hz, allowing it to capture everything from deep cinematic rumbles to tighter musical bass.
