Screw it into the surface you want to vibrate & let it screw you!
Thank you Thomann!! I was searching all over the place & the internet for Buttkicker LFE but they can't ship out to my country - Malaysia (My own country doesn't sell Buttkicker LFE) BUT THOMANN DID!! Purchased with THOMANN on Friday & item received on Tuesday (within 4 days) & I've already mounted Buttkicker LFE underneath my sofa's wood frame!
(For those who are wondering how the Buttkicker LFE feels, it's the same heart pumping vibration you get if you are seated at the back seat of a car when the subwoofer volume is high. But with Buttkicker LFE, the punch is very very strong).
Cheers THOMANN!
