    Getting just a bit long in tooth but a classic
  

*by J***D on Reviewed in the United States on May 13, 2013*

This is a very solid introduction into the science/art of measuring loudspeaker performance and obtaining small signal Thiele-Small parameters. Probably not well suited to the reader w/o some background in engineering mathematics. Such readers may be better served by more of a cookbook approach as there is plenty of math and graphs on these pages, though none requiring more than solid pre-algebra level of ability.From a novice DIY perspective, my one wish is that there were more commentary about designing loudspeakers instead of simply measuring them. Dr. D'Appolito has designed many critically acclaimed loudspeakers for more than one manufacturer (Usher and Focal come to mind) and a case study or two would of added much IMO. Still a very worthwhile purchase that reviews T-S parameter acquisition, MLSSA and some basics of digital signal processing theory. Especially informative were the case studies where he shares several projects he has measured and the insights into performance gleaned is invaluable. Its a keeper for the reference shelf.  Wish there were a second edition. BTW there are some more recent articles of Dr. D's on the net summarizing some of his thoughts on speaker design if interested.

    Great content, print not so great
  

*by J***H on Reviewed in the United States on January 15, 2024*

This book is an important resource on speaker building and testing, which makes me wonder why its print quality is so bad. Everything is extremely small. Some figures simply cannot be read due to the blurriness of the print. If that wasn't enough, it's like the printers were trying to save ink with grayish print.
