More Information
Summary:Passive radiators of the same effective vibration area and the same effective vibration mass disposed in mutual opposition, and driver units of the same effective vibration area and the same effective vibration mass disposed in mutual opposition, are mounted to a bandpass type enclosure. The vibration-reaction forces of the opposing passive radiators and opposing driver units on the enclosure are thereby mutually cancelled, and enclosure vibrations are thus greatly reduced. Powerful bass output can be achieved because the diameter of the passive radiators can be increased at will and the use of two passive radiators achieves an extremely large vibration area.
