The dual resonator chamber with variable volume includes first and second housings. The second housing is slidably mounted within the first housing such that a second inner neck portion of the second housing is slidably mounted about the first inner neck portion of the first housing and forms a fluid-tight seal therewith. A sliding wall is slidably mounted within the second housing, dividing the interior thereof into upper and lower resonator chambers. At least one first actuator selectively adjusts the height of the sliding wall with respect to the second lower end of the second housing to selectively adjust volumes of the upper and lower resonator chambers. At least one second actuator selectively adjusts the height of the second housing with respect to the first housing to selectively adjust the neck length of the lower resonator chamber.
