Hi all,
believe or not, it's taken me more than 10 years to finally take those Millenium and Excel speakers off the shelv in my basement and build some Small Thor enclosures for them. I had built original Thor (or rather Hobby Hifi's Evo 04 modification) back in 2003 or so, but when I read about the new enclosures here in the forums I crashed those new boxes and wanted to build new ones. Well, that went quick... 🙂
I know you've all probably moved on to different speakers and are already bored by the Thors, but I'd need some help with the XO. I want to build Jim's improved version, but there are many schematics flying around those threads and I can't figure out which one is the patest and greatest. I managed to find

Is there any chronology to those? What are the differences in terms of sound? Any help would be greatly appreciated!
Thanks, Hauke

They are all much the same, IMO.
The RL coil at the bass input is a bit of extra bafflestep. Can't really see much point in conjugating the Fs impedance peak of the tweeter in a third order filter.
So I'd start with this third one, which is closest to the original Thor Mk III design:
Easier to build, too. Where it says 5.7uF, use 5.6uF.
