A New Set of Fifth and Sixth-Order Vented-Box Loudspeaker System Alignments using a Loudspeaker Enclosure Matching Filter: Part I

Authors: Mellow, Tim John

AES Convention 112 · Paper 5505 · April 2002

Abstract

A new vented-box loudspeaker system is introduced that can be tuned to provide a pre-determined frequency response shape over a fairly wide and continuous range of box volumes. A conventional high-pass filter only allows the system to be tuned to give a particular frequency-response shape if the box volume is correct. The conventional filter can be either isolated (i.e. buffered by the amplifier) or non-isolated (i.e. between the amplifier and loudspeaker). The latter could be a passive filter that interacts directly with the complex load-impedance of the loudspeaker. Consequently, the two cases require different box volumes. A new current-feedback filter is introduced that can provide a continuous range of alignments from isolated to non-isolated.
