  • Acoustic speaker enclosure having a stacked construction
    Patent number: 5661271
    Abstract: An audio speaker enclosure comprises a plurality of structural layers or panels having openings which are in communication. Layers of damping material are interspersed between the structural layers, attenuating vibrations and preventing interaction between drivers in separate chambers. Additionally, the openings in the structural layers may vary, allowing the acoustic chamber behind the driver to have curved surfaces, thereby reducing resonance.
