Dahlquist speaker models, question/experience and today

Some of us older audio-piles started with Advents, KLH and others...but most of my friends had the Dahlquist DQ-10 at one time in their audio journey. I know nothing about the 9, 20i, 30i etc. If any of you have experience and can compare the DQ-10 vs later models it would be interesting to hear you thoughts/views/experience. Thanks.

I bought a nicely restored and upgraded pair of DQ-10's with custom-stands from a nearby seller. $375! A major bargain! And still competitive with today's four figure speakers! 
I'm not sure if he is still an audiophile or not. I don't see him much and life had been hard on him and I did not ask last time we met.
I'm assuming Dahlquist is not longer in business?
N90 sorry to hear that

no they faded away after Jon , I think they had some decent sounding gear but never replicated or chose to extend the DQ-10 magic...
The magic lived on.  I still have a pair of DQ 20s which have better drivers than the 10 and are still magical.  Regnar provides rebuilds for the woofers and midrange and last I checked scanspeak still has the tweeters in production 30 plus years later.  the 20i and 30s are also nice speakers as are the 9s and the 10s put them on the map but I believe the 20s were there finest hour.  All can be had for a song and can be repaired or upgraded via Regnar if you have minimal skills with a soldering iron.
...eddie, thanks for the info/suggestions.  

I have owned a very large number of speakers over the years...and stacked Advents, Dahlquist DQ-10 and Magnepan 20 are the ones I remember most. 
I would mention Karly, Jaleen and Susanne...but the speakers were cheaper and more reliable.
