The Jordan Loudspeaker Manual

The original Jordan Loudspeaker Manual was produced in the early 1980s. Ted realised that a technical background would be beneficial to customers and clients who were using the Jordan 50mm module.

Drawing on material from his 1962 book, Loudspeakers, it gave a comprehensive analysis of loudspeaker design and offered the rationale behind the 50mm module, which seemed to go against so much of commercial loudspeaker practice at the time.

The new Jordan Loudspeaker Manual continues these ideas, updated to include Ted’s analysis of recent developments in computer-aided design and modelling. Individual chapters are available as PDFs.
