AB  - The vibroacoustic behavior below 1 kHz of a prototype closed-box loudspeaker has been studied in detail by comparing measurements and element model simulations. Sound fields were measured using a microphone array of 90 electret capsules and vibrations using a laser vibrometer and accelerometers. Simulations have been carried out using analytical, finite, and boundary element, and finite difference methods. The enclosure conditions were varied from fixed wall case buried in sand to free-standing empty box and to free-standing damped box. Two positions of the driver in the front plate were examined (only the 'rim' position is documented here). The applicability of each modeling technique is discussed.
