There is Nothing Passive About These
CARBON PASSIVE RADIATOR
Our uniquely tuned passive radiators use special suspensions, now with an additional 30mm of linear travel, to produce performance far beyond conventional subwoofers. Our new SuperProgressive™ passive radiator produces extremely long travel allowing for very loud output while retaining the variable stiffness of its suspension. This allows it to act like a sealed box compact 12” design at low volume and a high output 14” design at its limit.
