Sony Three Box System Party Speaker X30D is a Sound Pressure Horn for bass you can feel and be blown away by soul-shaking bass with the Sound Pressure Horn.

An internal folded horn design efficiently increases acoustic pressure by pushing energy through an amplifying duct. The result is far more effective than traditional, energy-wasting amplifiers and signal processing, adding a boldness and body you can really feel to all your bass lines.
