Before you spend a lot of money on amps for these speakers, I'd highly recommend a little chip based amp like the Folsom model. With 94db sensitivity they just don't need a lot of power, and those amps sound about as good as any amps that I have heard.

I am running Jeremy's amp with my wedgies and servo amps.  It is a lovely sounding combination.  I also have the boards for his new amp and I am looking forward to putting it together as well.

Danny, could you pls post a double plot of acoustical output AND impedance?

What frequency do you recommend for a line-level hi-pass filter for these?

The impedance plot is posted above.

The measured frequency responses are posted here: https://www.audiocircle.com/index.php?topic=155092.msg1679963#msg1679963

You can cross these to anything that will play up to 200Hz.

And they naturally roll off below 200Hz. So any filter that removes the first two octaves will be fine.

OK; that sounds like a natural for the 0.022uF Miflex KPCU copperfoil/'propylene&paper/oil into a 100K load for 72Hz.

Yes, that is correct and should work great.

Progress continues!  I started glueing up the subwoofer base flat pack.  A HUGE “thank you” goes out to Jay, who went above and beyond during this process.  If any first-time builders are reading this, and are considering taking the leap, take it from this newbie that you should jump in with both feet.  Jay’s flat pack is a no-brainer.  Top notch quality, and truly the most sincere, honest, and forthright service I’ve experienced.

I’ve included a picture of the first sub getting glued up.  I’ve also included some pictures of Jay’s insane ninja packing skills.
