Another way to say the same thing is that "free air" speakers do not need the back pressure of an enclosed space to keep the cone from deforming. The other extreme FYI is "acoustic suspension" where the cone feels loose when uninstalled and distorts across the band and can even self destruct if played that way. This design uses more power (to overcome the back pressure) but the controlled cone movement and complete isolation of the +waves in front from the -waves behind yield a much cleaner sound. Also saves space and is kinder to neighbors.
