Spare Wheel Active Subwoofer

EMPHASER’s innovative subwoofer design brings unbelievably high pressure and sound from the smallest space. Thanks to the extra-thick butyl rubber surround and extra-heavy, torsion-resistant stainless steel membrane, the EBS111A now blows another wind in the car. Fat Beat is also available on the EBS108A – thanks to the bass reflex principle, the 20 cm high-performance subwoofer pushes impressive bass waves.
