GPA Maestro Logo The Illustrated Guide To Loudspeaker Healthcare  - subtitled, The Adventures of Captain Rock and his Sidekick "Roadie", this is a fun piece written by our friend Barry McKinnon, who worked for an Altec Lansing Engineering Sound Contractor in Canada in the late 1970's.

GPA Maestro Logo Interpreting Loudspeaker Specifications - This material was originally presented as part of a four-hour class taught by Barry McKinnon during the technical training courses at the 1998 NSCA (National Systems Contractor's Association) trade show in Las Vegas on 4/27/98. It is an excellent help for those who are unable to filter through the mess that most of the speaker manufacturers generate as specification sheets for their products (except for Altec Lansing).

GPA Maestro Logo Cluster Design for Intelligibility - So many today are going to the "one-box-does-all" (array) type of system design, to the detriment of proper coverage and intelligibility. In this article, Barry McKinnon shows the fallacy of this method, how it adversely affects directivity, and how to design professional sound systems the RIGHT way.

GPA Maestro Logo 3D Computer Modelling Of RoomsBarry McKinnon on the modern-day design techniques so often used, often abused, and rarely understood.

GPA Maestro Logo Loudspeaker Directivity As A Design Issue - To most people, directivity in sound system design is not an issue. Their only concern is "How loud will it play?" or "How many watts is it?" Never before has the old saying from vaudeville been more true: "If you can't be good - be LOUD!" In this article, Barry McKinnon exposes the mistakes of the modern system designer who ignores directivity and goes for sheer volume in decibels only.
