Made these a few years ago and I was never really happy with the midrange [ my fault using El-Cheapo drivers] and I'm looking now to rebuild them.
Last XO was a cascaded in the bass with a largish inductor before the 10" woofer in the 20 litre sealed box, wired in series with the dual 8's in parallel. For the Aussies the 8" are old Jaycar woofers I got on clearance, CW-2110.
They have a Qts of ~0.95 and a peaky hump in response right on their Fs at 40hz.
Another fun but cheap project to give to somebody doing me a favour with renovations.
Just looking now at some S/H Vifa drivers on eBay for the midrange. I have some cheap silk dome tweeters suitable for tweaking I intend to use.

Wow - look at all the drivers the sound is spread across. That sealed driver for the low-low end is going to make this sound different than an ordinary OB.
So I just bought the Vifa S/H from eBay

I'll need to go back to the beginning with the crossover anyway so going from 4R to 8R shouldn't be much of a problem.
Anybody worked with these little midrange and can give any insight?
adason you posted picture makes me feel really inadequate but I like the staircase.
