So I have this old booklet of speaker designs or kits using Audax drivers all by Vance Dickason and published by Audax.
All the designs in look kick-a**. The 2-way designs are still on the Audax website. The 3-way designs are hardcopy only.
The A851 looks great. It uses an AW025S1, HM130Z0, and HM210Z0. These drivers are still listed on the website, so they seem current, but I can't find a distributor that has both mid and woofer available, and none seem to list the tweeter.
Anybody have any insight? Know a super-distributor? Know of someone who modified these designs? Thanks.

AW025S1 $15.50usd each @ Madisound

Also AW025S1 $35.50usd each @ Zalytron
Also, on Solen's website, I read that HM130Z12 replaces the HM130Z0 and the HM210Z12 replaces the HM210Z0. I don't know what they mean by "replaces". Check the specs to see if they are a drop-in replacement.
HM210Z0 may still be available at
http://www.q-components.com/
for about $100usd. (they are in Canada)

I personnaly built a pair of of KSL9 based on the HM210Z0. This was a great mid/woofer but unfortunately, this design was widely inaccurate in terms of alignement and crossover 
.

Indeed, I implemented an acceptable version of this loudspeaker. TBC...
Anyway, the point is that the HM210Z0 seems out of production now. Being replaced by the HM210Z12 which have very different Thiele/small parameters, it's not a 'drop-in' replacement for the HM210Z0. Don't misunderstand me, the Z12 IS surely worth the look and could possibly give an excellent loudspeaker; just not in the same enclosure that would have accomodate a Z0.
Same for the HM130Z0: discontinued and replaced by the HM130Z10/12...

I'd love to know how to get hold of a copy of the A851 design by Vance Dickason that you mentioned at the begining of this thread. I have aquired a pair of Audax HM210Z0 and HM130Z0 drive units and was looking for a good design that used them. Does the Vance design look interesting/good?
IPL acoustics sells both these drive units here in the UK but I expect you are looking for a supplier a little nearer home!

I never attempted it because I thought the drivers were overpriced at the time, but now that Audax stock liquidation sales are starting to happen, who knows?
Also, there is another 3-way design named A841 which uses the TW025A1 + HM100G0 + HM210G0 in the same brochure if anyone is interested.

Thanks for posting those details.
Looks like a promising design. Not sure about the metal dome tweeter though. My only source is CD and I wonder whether its a good combo, not that I've ever tried one mind. I'll see if I can find any reviews of it or speakers that use it.
Might be able to swap it for a fabric one but how easy this is without upsetting everything I don't know. Cross over freq looks safe enough for most tweeters though.
Would it be a pain to blow up the crossover schematic, and cabinet dimensions, they are a bit small to read the text!
Thanks again

Having tried almost anything between 30 and 60 liters (1,06 and 2,12 cu. ft) and a 40 liters (1.40 cu. ft) box with two 1,75" X 6" ports seems to yield the best results out of my HM210Z0. Stuffing has large effect on my setup so this aspect is not no be neglected.
BTW the A851 have a woofer cavity of 39,39 liters which I think you can't go wrong with...
The idea I have presently is to couple the Z0 with an HM100Z0 and a 3/4" tweeter, but the HM130 is certainly a valid possibility but with an 1" tweeter.
