Ultimate DIY speaker design?



Hey everyone,

I've got the bug to build a set of DIY speakers, I havent built a set in years.

Is there an ultimate design out there that anyone can recomment?

I saw the WATT Puppy designs out there but I am wondering what else I might consider trying.

Note, I definitely dont want a kit, I wouldn't mind doing a custom design I come up with myself but I would ideally like to try a clone of something with top pedigree.

Thanks in advance!

In the old days one system described in Audio was concrete built alongside the house, the exit of the horn into the house was 6' tall. It could blow out candles across the room or make your trowser leg flap if I remember. It was mono and crossed at 50Hz I think.

some pretty radical diy sites.

Tony Gee seems to like high price drivers, series xovers, and fancy cabinet work.

His version of Sonus Faber inspired speakers.
Second the Linkwitz Lab Orion+. Hands down winner not just for DIY, but compared to any commercial speaker. (BTW it's Seigfried Linktwitz)
You might consider John Kreskovsky's NaO. I built the NaO IIt. A really great, DYNAMIC dipole!

I had a fellow over that built the Orion. He told me they were very similar. A little easier build, IMHO.

For less money, the NaO mini would be nice.
