Welcome to my site. It is intended as a place to share all kinds of stuff related to audio on an irregular basis.
Klarde und Happers is the name I give to all my DIY loudspeaker designs. I chose it because German-sounding surnames or combinations thereof seem to add a touch of credibility to just about anything. It is also a play on words in Dutch, where “harde klappers” means something like “speakers that go loud”.
I’ve been into hifi since around 2005. In 2014, I graduated from Delft University of Technology on a directional speaker design. Around the same time, I was involved in founding Dutch & Dutch and designing (among many products that never went to market) the 8c monitor.
I now work in Product Development at ETAP, an international lighting company, which means I can pursue hifi as a hobby again.
I hope you enjoy this page. If you have questions, things that I might find interesting, or constructive criticism, feel free to contact me. I can’t promise a quick response.
