A single-seat transducer with excellent musical response; the ButtKicker mini Concert adds amazing impact and tone perception – from deep bass to lower mid-range.
The ButtKicker Advance is a patented 4 ohm low frequency audio transducer that features a 1 lb (0.45 kg) magnetically suspended piston. The ButtKicker Advance is accurate, provides powerful frequency response, is virtually indestructible, and requires no maintenance.
