The converter includes an electro-acoustic transducer and a variable density hollow body. The transducer includes a piezoelectric sheet and two conductive electrodes. One electrode is disposed on each face of the sheet. Coatings are optionally disposed on each side of the transducer. The transducer is wrapped around a variable density body which may be filled with an acoustic dampening material. The acoustic speaker system enclosure includes a hollow ellipsoidal woofer enclosure with a portion of its outer surface for mounting an electro-acoustic converter, and optionally, a converter cover. The acoustic speaker system also includes an elastomeric cover that is fastened to the dome portion of a woofer.
