Abstract
A speaker includes a housing and four substantially similar electro-acoustic drivers secured inside the housing. The drivers are driven by substantially the same audio signal and are arranged such that the net mechanical vibrational force between the drivers and the housing is substantially zero. Four substantially similar passive radiators are secured inside the housing and driven by acoustic energy from the four drivers. The passive radiators are arranged such that the net mechanical vibrational force between the passive radiators and the housing is substantially zero.
