10. has a passive radiator

A passive radiator looks like a normal driver (speaker) from the front, but on the backside all of its 'guts' are removed. Passive radiators allow woofers to produce deep tones that otherwise may not have been possible. They can have the same sonic output as larger speaker cabinets, but in a much smaller size.
