Snell Acoustics, a manufacturer of loudspeakers for more than 30 years, has announced that audio designer Joseph D'Appolito, Ph.D, whose name is synonymous with the paired-vertical array, is now exclusively Snell's full-time chief engineer. In his newly designated position, Dr. D'Appolito will work closely with David Logvin, Snell's Senior Design Engineer, to direct new product development.

An authority in acoustics, speaker design and measurement techniques, Dr. D'Appolito has been Snell's chief engineer since joining the company in 2003 and has spearheaded the design of many of the company's products, including Snell's new Illusion Reference Tower. He has also been directly responsible for the Snell Series 7 models, including the complementary in-wall and in-cabinet speakers. Now, with Dr. D'Appolito's exclusive commitment to Snell, he and the company will be able to concentrate on the obvious synergies between his engineering pedigree and Snell's expertise in the design and manufacturing of loudspeakers.

Designer of the "D'Appolito Array"

Dr. D'Appolito is best known for designing the popular loudspeaker geometry commonly known as the "D'Appolito Array," which is now incorporated into the designs of many speakers designed and manufactured in Europe, Asia and the U.S. The technique, when properly executed, sandwiches a tweeter between two midrange drivers - so that the tweeter's output is directed primarily at listeners in the horizontal plane, minimizing reflections with the floor and ceiling.

In addition to designing the D'Appolito Array, Dr. D'Appolito has been at the forefront of commercial loudspeaker design for over twenty years. Prior to joining Snell, he was instrumental in the design of more than 80 loudspeaker systems and related audio engineering projects.

Dr. D'Appolito is the author of an
authoritative book on loudspeaker testing, Testing Loudspeakers (Audio
Amateur Press). In addition, he has contributed to both the technical
and popular literature on loudspeaker and crossover design. He has
served as Contributing Technical Editor for books on home and auto
loudspeaker construction published by Master Publishing, and has
authored more than 30 journal and conference papers covering
applications of modern estimation and control theory, statistical
signal processing, stochastic systems identification and modeling, and
a broad range of navigation, guidance, communications and signal
processing issues.

Snell's New Illusion Tower

Dr. D'Appolito's most recent
accomplishment at Snell has been directing the design and creation of
the Snell Illusion Reference Tower loudspeaker, a product with no
limitations set on acoustical design, materials or creative design. A
uniquely designed pair of tapering towers, Illusion houses a full
spectrum of transducers, integrated with a custom crossover network.

Dr. D'Appolito holds BEE, SMEE,
EE and Ph.D. degrees in electrical engineering from Rensselear
Polytechnic Institute, the Massachusetts Institute of Technology, and
the University of Massachusetts.
