ABSTRACT:
A loudspeaker enclosure with precisely dimensioned chambers to control and develop loudspeaker back wave energies almost exclusively as acoustical tensions. Focusing of these acoustical tensions is accomplished within each chamber so as to localize the several points of acoustical energy concentration optimally at the aperture positions between chambers. The second and also a third chamber operate to maintain proper load levels throughout the complex acoustical air column until eventual release into the listening space, the third, as well, creating essential reverberation and depth.
