An acoustic device including a first passive radiator structure and a second passive radiator structure is provided. The first passive radiator structure includes a passive diaphragm mechanically coupled to a first enclosure member via a first flexible suspension element, and is configured to vibrate relative to the first enclosure member. The second passive radiator structure includes a second enclosure member, and is configured to vibrate relative to the first enclosure member. The second passive radiator structure further includes a second flexible suspension element mechanically coupled to the first enclosure member and the second enclosure member. The second passive radiator structure further includes an active electro-acoustic transducer mechanically coupled to the second enclosure member. The second passive radiator structure moves when the active electro-acoustic transducer vibrates. A first mass of the first passive radiator structure is less than a second mass of the second passive radiator structure. During operation, the first enclosure member experiences substantially no vibrations.
