Here's a list of speaker design links, some are pretty interesting off the wall ideas, some are basic plane jane stuff for beginners and to file for reference.  Please feel free to add your own links, comments, and ideas.

A great addition to the list.  I think they deserve their own post, but let me know if you want them added to the main list.

Yes please do. It was far too many for me to want to do since there are obviously several repeats and certainly a few dead links.
Thank you

I like this web because of measuring db and phase in the real baffle, not the spec from raw driver. This make the crossover complied with the driver in the real enclosure.

The latest speaker I 've ever built.
