@hifiside - just a note...I usually just start typing in JF... or Jule... and my browser pre-fills the address. Last week I was on a different device so just typed in Julefidelity.com which turns out to not be a registered website. You might consider buying it and just redirecting it to JFcomponents.com

lol. That’s a long story but I use to own it till godaddy took it and now is holding it for ransom at $2700.
I bought 4 of those for $4.88 each. Two were really quite good above 3k. The other two were junk. I'm going to use the two good ones in a new three way project.
I bought 10 pair, 4 pair matched nicely, 1 is a dud and 11 I can use in my new commercial build with the Aura drivers I got from Ron E. I might buy 20 more.
Might you try that without the faceplate between? Would get rid of that transition and reduce the throat depth. I suspect it could clean up the dips a bit.
I haven't measured the 1204s in the wg148s yet.. I trust your measurements much more than mine. That is why I ask.
I wanted to try and mate it up to the MAC-06. Just eyeballing your off axis measurements against each other it seems crossing somewhere between 2-2.5khz would be nice.
I reemed the holes with a unibit one size up, bolted right on. I was going to machine a thin aluminum plate for these Visaton like I did on the Pilot build and try that.
As far as I can tell the two Visaton waveguides have the same flare geometry and mounting for the tweeter, just different baffle mounting shapes.
I removed the tweeter faceplate entirely and crafted some gaskets out of sheet hobby foam, then sandwiched the diaphragm, motor and gasket directly to the waveguide mounting plate with a backer plate and long screws. That way the dome is as flush as possible to the waveguide throat. Based on my basic research it seemed this can help prevent throat cancelations for a dome in a waveguide. Though it is probably not a viable commercial option due to relying mostly on friction and tension to hold it in place... I suspect it might not withstand shipping. So I totally understand why this would not be pursued.
OK I took the rabbit hole. For the mounting flange, I would have my machinist make a thin aluminum mounting plate, but this should give us an idea on bettering the FR measurements.
I use a pc of Formica for the prototype flange.

Scroll down the homepage that Dirk posted, toward the bottom before the Contact Us section.
Yep, already done.

Ouch! Yeah, I was thinking for $12 a year just buy it, my bad!
Paid a visit to the JF Components website today. I see a few new drivers in stock that were not there last week. Including some Peerless.
Yep. More to come> @Jakes_dad said:

Hey.!!!!! Purfi….! This is how $20 GRS speakers are packaged. Wow impressive…

Let the remodel begin. My free shelving from the local grocery store.😎

That's what I like to see. I wish the best to you on your endeavors.
Nice!
Matching some Buyouts.😆

A set of these today too.

A Buyout Square Tweeter on IEC baffle. 0-60 deg.
https://www.jfcomponents.com/
They sure are pretty. And -50dB 2nd order from like 2.5khz on up? Sweet.
And it has a top end! Though it's not often you can guess Fs strictly from a response chart.
AND - guaranteed to work/matched!!
Nice plan. Love those Aura NS6
Yes. If there bought from me they will come as a matched pair. Or you can buy 4 from PE and hope 2 match.😆

The JF-1204F in a Visaton WG 220x150. The FR is 0-60 Degs

I don't see these on your site?
Visaton? Nope, I’ve emailed the company just waiting a response.

What mods are you guys doing to these tweeters to bolt-on to that 22X15 cm Visaton Waveguide, if I may ask?
