Modulus Bullet Speaker With Passive Radiator
Designed for use where sound is to be focused in a particular direction/area and added bass augmentation is required. The back-firing passive bass radiator offers superior bass response in addition to the excellent capability of standard Modulus 4.5″ Bullet Speaker. Install the speakers with the passive radiator end pointing away from the listening area (can be identified by the hole on the rear of the armature).
