The Zen Open Baffle is the highly-touted open baffle design that Decware founder Steve Deckert claims produces percussive, deep bass down to 50 Hz. It achieves this bass response by way of a network of two resonant chambers and a horn, incorporated behind the baffle. This network amplifies the rear-firing energy form the Zen's single full-range driver, and can be adjusted for bass response by opening or closing a valve a the top of the chamber, underneath the back of the driver.
