DIY high end speakers?

Is there any consensus on which of the published (via Internet) speaker designs / kits are actually worth it? I am very handy (I design and build furniture as a hobby and have a full shop) and as a result am considering going the DIY route for speakers but I need a starting point for my research.

What are some good links and resources for me to check out and see if this is a good way to go?

Thx
