High Quality Horn Loudspeaker Systems

The book "High Quality Horn LoudspeaHorn Book Jacket V3 front w releasedateker 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.

Second Print Run has been Delivered

We have received the new batch of books from the printer, they are now currently in our warehouse, ready to be sent out to our distributors. Lean Business Audio is local and should be able to get books on short notice, so if they haven't updated their website, send them a message and let them know you want to buy a book. It will take a little longer to get stock to Parts Express as we need to ship overseas, but things are moving.

Latest Update on Second Print Run

The corrected manuscript has been submitted to the printer, and we have received a proof of some of the pages to make sure the images print well. As some of you may have noticed, some of the pictures in the first printing were very dark, and this should hopefully now have been corrected.

The printer informed us that due to Brexit and Covid, some print companies have been forced to downsize or close, so there's currently a shortage of print capacity in the UK. CPI Print, which we use, also have an unprecedented volume of work. The lead time for the book is therefore longer than anticipated. It looks like production will not start up until mid or late January, with additional lead times in order to get the books out to Lean and Parts Express. We are sorry we weren't able to get the books ready for Christmas, but at least it's moving forward!

We will keep you updated.

Stock Status and Second Print Run

The book is now nearly sold out. The last few copies are on their way to Parts Express now and should be available on their website soon.

Thanks to everyone who bought a copy! 

The stock ran out quicker than expected, but don't worry: we plan to do a new print run soon. We wanted to correct some typos first, but these will just be minor corrections of mistakes. The content will be the same as the firt printing, and all important (factual and mathematical) corrections will be listed in the Errata section on this website.
