Brad, what kind of caps did you use? I may want to give this a try. I agree with you on the benefits of the alternate tuning mod all the way.

I'm still using two paralleled Auricap's (sum is around .98uF ~ equivalent 1uF), but I intend when I get around to it to try a 1uF Mundorf silver/oil.  I really liked what the Mundorf's did in my preamp and amp.  

Btw, as an experiment, in an attempt to get the Aurum Cantus tweeters closer to the Fostex driver (without cutting a hole in the baffle - yet), I duct taped the tweeters to the outside side of the cabinet.  It looked like crap but sounded allot better this way.  It probably has something to do with the way these tweeters have great horizontal dispersion, but restricted verticle dispersion.  I'm hoping when I finally cut a hole in the baffle and mount the tweeters directly above the Fostex that it will retain this improvement (and I'm expecting it will).

Several considerations:

Time alignment?  In HDTII"s, and variations of the Radial, the ribbon is placed in nearly the same plane as the dust cap (recessed from the baffle face)

and is

Decoupled:  the tweeter is isolated from the cabinet so that it doesn't react to vibrations created by lower frequencies and resonances in the cabinets.  Maybe the duct tape lets your tweet be decoupled.  

I thought I read somewhere Steve D saying that with higher x-over frequency of supertweeters, the less critical it is to have drivers right next to each other.  

Also might have to consider how your tweeter will perform with a wide baffle around it vs floating.

Well, maybe it could be considered half floating since there is no baffle to the outside of it (side placement) or above it (top placement). Also, the front-back alignment with cone is the same.  I also do not agree that a drive with such low x-max and low mass cone is vibrating the extremely heavy HDT cabinets to any degree which is affecting the tweeter.  It's clear to me that the dispersion characteristics are playing a large part, in addition to it just being at least 4" closer to the Fostex.

Well, I don't know if I'm first. But I placed a purchase for the new DFR8 drivers.  I decided against upgrading my existing FE206EM's, what with the cost of shipping, potential for damage, etc.  I'll prob try to sell them used locally.

Brad,

I couldn't start the thread without also ordering. I ordered last week but no word yet on shipping date.

I'll be sending my 206e's off for modification in the near future.  They're just hanging around in some BR cabs.

What I really want with this upgrade are plans to build the ULTRAFLEX Cabinet!

and a CSP2 kit...

Hello Yoda,  I found the page for the ZSP-1 kit and the SE84CSP preamp.  What is the CSP2 kit?  Do You have a link for it's page?  
Thanks

Yoda, as per a discussion I had with Steve, he says the HDT with the new DFR8 driver is now on par with the Ultraflex in the midrange.  His words were that he used to lose sleep over how the Ultraflex sounded better than the HDT particularly in cabinet colorations and pulling the disappearing act.  But with the DFR8's in the HDT, he's sleeping fine now Wink.  However the HDT goes lower (~35hz vs. ~58hz).  So you may want to reconsider your building endeavors, or at least wait for a few of us HDT owners to get our DFR8's in and give our opinions.

Has anyone heard when the DFR8's will start shipping?  I may have to call Steve again and ask.  Zygi, I assume you will be putting a pair in your HDT's?
