Advantages of Passive Radiator

backside show of vibration diaphragmPassive radiators allow woofers to produce deep tones that otherwise may not have been possible. Depending on the tuning when incorporated, a passive radiator will start to move as the drive woofer begins to produce lower frequencies. By engaging at this point, the passive radiator absorbs energy from the drive woofer thus reducing the drive woofer’s motion (we call this dampening). Since the drive woofer is now moving less, there is less risk of damage occurring due to over excursion (speaker moves so far it breaks). There are two main advantages here:

1.   The motion of the drive woofer is dampened thus flattening the frequency response; this makes for smooth sound reproduction.

2.   Passive radiator systems can have the same sonic output as larger speaker cabinets, but in a much smaller size*.

In a nutshell, when a passive radiator is tuned properly it can greatly enhance the sonic capabilities of a speaker in regards to low frequency production.
