This site contains information about my main hobby, do-it-yourself
audio. It is not very frequently updated, so much of the stuff can be
quite old. I try to keep the progress of my system fairly up to date,
but I can't keep track of every little change.
Amplifier and
speaker projects are usually not described in detail, because that
takes alot of time that I would rather use for completing the
projects... Some of my older designs have schematics and circuit
description, and I hope to put up some more.
Please excuse the lousy picture quality. Because of the little space here at the free Geocities pages (15MB), I have to keep the image files small.

Many of the projects described on these pages contains potentially lethal voltages. Do not attempt to build anything of this if you don't know what you are doing. Always let an electronically trained person rewiev what you are planning to build and what you have buildt. 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 irreversible. Horn speakers will sound very clean even at extremely high levels, and will not give you the "distortion warning" direct radiators provide.
