Welcome to my restructured homepage. It was time to do a complete rebuild to make it easier to maintain, and also to make it look better.
I'm now officially a horn researcher, due to my position as a PhD student at NTNU (see my first blog post for details). I hope these pages will become filled with the results of this research. But the stipend is quite limited; there is not much money left after my bills are paid. So if you want to donate some money to this research project, please note the Paypal donation button at the bottom of this (and a few other) page(s). I will keep you updated on what the funds are used for.
I support the TurnMeUp! campaign to bring the dynamics back to recorded music.
Many of the projects described on these pages contain potentially lethal voltages. Do not attempt to build anything of this if you don't know what you are doing. Always let a person trained in electronics review what you are planning to build and what you have built. And if you get hurt or your house burns down after trying one of these projects, don't come running to me.
The horn speakers shown on these pages are capable of providing sound pressure levels that may damage your hearing irreversibly. Horn speakers will sound very clean even at extremely high levels, and will not give you the "distortion warning" direct radiators provide.
I ASSUME NO RESPONSIBILITY FOR THE USE OF THE INFORMATION PROVIDED ON THESE PAGES.
