The "Acoustic Resistance Box"-A Fresh Look at an Old Principle

Authors: Holmes, Thomas J.

Journal of the Audio Engineering Society · Volume 34 · Issue 12 · pp. 981–989 · December 1986

Abstract

Unidirectional woofer systems preferably use resistance-loaded ports to control the pressure gradient. Analysis of the acoustical analog circuit shows how to optimize the design for any specific purpose: one can trade between box dimensions, frequency range, internal pressure, driver volume velocity, and radiation efficiency. The predominantly resistive rear load on the driver simplifies the application of motional feedback.
