WELCOME! This page is a not-for-profit collection of hobbyist content. It was put up to display some of the better speaker projects I've built. I've been a hifi hobbyist for many years, and music is a big part of my life. I've built a lot of speakers, some for no reason other than to see if they sound good. I've built a lot more than what you see here. These are just a few the recent ones I decided to document.

All designs here are free for non-commercial use. This web site was posted for the benefit of the DIY loudspeaker community, from which I learned so much over the years.

There are some "Cheap But Good" speaker designs here and there are also some very high end designs. If you're looking for some DIY designs that will outperform commercial retail products costing 5 to 10 times more, one of these designs may suit you. If you're looking for some assistance in picking drivers for your own projects, you'll find measurements and driver reviews here.
