Joseph A. D'Appolito is best known as the developer of the "D'Appolito Configuration" which was first described in his "A Geometric Approach to Eliminating Lobing Error in Multiway Loudspeakers"[1]. This configuration is recognized by loudspeakers which have two midrange or woofer drivers arranged vertically above and below the tweeter[2] and implements the 3-rd order (18dB/octave) crossover allowing the drivers to have similar horizontal dispersion, resulting in absence of any sudden change in directivity with frequency. D'Appolito is the author of "Testing Loudspeakers" and a contributing editor to AudioXpress magazine[3]. He is also the owner of a consulting firm, Audio and Acoustics, Ltd. whose clients include Snell Acoustics; HECO/Recoton, GmbH and Usher Audio Technology[2].
