The book "High Quality Horn Loudspea
ker Systems" by Bjørn Kolbrek and Thomas Dunker was released in November 2019. This website will keep you up to date with availibility and distributors, and we also provide extra material and errata. The book is now in its second print run, and most of the errors from the first print run have been corrected.
Currently the book is available from Lean Business Audio and Parts Express.
The second print run recently sold out, but don't worry! A third print run is under way with delivery to the warehouse 16 May. For customers buying from Lean Business Audio the book should be available shortly after that, for Parts Express customers it will take a little longer as we need to ship stock over.
