A method for matching an acoustic load and an acoustic driver in a resonant acoustic system, and the acoustic system so formed. The load and driver may be independently designed. The invention provides, inter alia, a matching volume positioned between the acoustic driver and load that is substantially greater than a stroke volume of the driver. The matching volume is sized such that, in combination with the moving mass, the characteristic stiffness of the acoustic driver and the characteristic load impedance, a resulting pressure wave produces an operating resonant frequency substantially equal to the preferred operating frequency of the load. Alternatively, or in addition thereto, a stroke volume of the acoustic driver can be adjusted.
