yogiboy, Acoustic suspension was instrumental in the early design of small speakers but it is essentially dead these days. Thiel/Small research into the design of bass reflex speakers allowed the design of small ported speakers which are more efficient and bassier although usually with less bass definition. Today the concept is misunderstood and almost everyone including reviewers call any closed box acoustic suspension when it almost never is. Acoustic suspension is a special variant of closed box and all closed boxes are not acoustic suspension. In fact the drivers today have design characteristics for bass reflex and can't work properly in acoustic suspension boxes. Edgar Vilchur must be rolling in his grave after his concept once had 2/3 of the audio market before Thiel/Small.
