Welcome to my website! Below you will find articles on some of the work done over the last decade. Building speakers has be on and off since high school, but with the availability of PC-based measuring equipment in the Nineties it took another direction as it became very much clear that doing crossovers by calculation and fine-tuning by ear had its shortcomings.
Over the years my focus has moved from small inefficient speakers to larger constructions providing the dynamics that make reproduced music live and engaging. Below you will find speakers ranging from 4 to 300 litres volume and I hope you will find inspiration for your next do-it-yourself project.

If you want modify the constructions shown here, please read "crossovers" before writing. In most cases you will need a new crossover and I would need your speaker on my test bench to tell you how.

In case you want advice on which speaker to build, please read both "choices" and "crossovers" before writing. I shall not recommend any speaker for reasons outlined in the file, and please do not ask about the sonic differences between two speakers. What I hear is unlikely to be what you will hear.

The constructions are divided into sections based on the main driver in the system, e.g. SEAS, ScanSpeak, AudioTechnology. All underlined text is a link, regardless of font properties.

If you have questions regarding your speakers, please include links, photos and crossover schematics if available! There are thousands of speakers in this world and I only know a fraction of them and can't google them all.

Regarding frd and zrd files for crossover simulation: I do not provide these from my library and please do not send your own for evaluation.

The common habit of anonymity on discussion forums is sad I think. If you cannot sign your statements, don't write them. If you have questions or comments, please state your name and the country you live in to give me an idea of the hifi environment you live in.
Feel sure I need your response to make this website better. I have a lot of mails and answering takes time and please do not feel neglected if my reply is short.

I regard all communication between you and me as personal, so do not post my comments or graphics on discussion forums, websites, etc. without my written consent.
