I’ll toss this out if ported, and possibly a long-shot, but worth a try: I had a ported speaker a couple of years ago which was probably not sized correctly and I very loosely stuffed the port and it pulled down the bump nicely. Probably give up a bit of low-end extension, but I found it a good trade-off.
Ed, scroll through that page, the port is shown.

Done! Another project complete. This one was definitely a journey, spanning multiple years and design changes. Now to enjoy them for years to come.
…of course till another project comes along.

I love the way they look. Also the drivers look badass!
I wish I could find the old kevlar drivers from Focal and Scan Speak. Always wanted to try them out.
Up the Irons!

Lots asking about the woofers, thought I posted some pics, but couldn’t find it.
So here goes…The aerogel surrounds had hardened up and I couldn’t find a proper replacement as they’re kind of a weird size. So I saw an option on AliExpress of a surround/cone assembly, took a chance and ordered them.
After receiving them and guessing it’d be close enough, I started checking out the driver. The cone to voice coil joint actually separated fairly easy. The tinsel leads attach to the voice coil between the cone and spider, so careful work with a scalpel and the cone and surround was removed.
I shimmed the VC in place and started fitting the new assembly onto it. I used some fingernail scissors to trim the opening in the fiberglass cone to fit snug on the VC. Once that was satisfactory, I used black CA glue to adhere the joint.
Next I used some SS wire to make the holders to keep the surround up away from the frame flange. Used the black CA again, ran a bead around it, then let the surround down.
Ran DATS and OmniMic and decided to give them a go.

wow! best mids? Is that from the Aerogels?
Yes, the aerogel cones were definitely something special. It’s weird no other manufacturer ever picked that up or tried any variation of it. The 4” size probably has a bit to do with it too, allowing a high xover point for better integration with the ribbon.

Ok, had to get to the bottom of the tweeters dancing to the bass.
This was first brought up to me by Rory at InDIYana this year. I didn’t notice it, not that the ol eyes are what they use to be, but I did ask if anyone else had noticed it, nobody said they did.
I checked it out when I got home, again didn’t notice it. They moved a little bit, I assumed just the way it is, I had them crossed at 4.2K, damped 2nd order.
PE SDC happened, Javad immediately told me after judging that he saw the tweeters dancing to the bass. He suggested maybe a leak ( as did Rory before)
So today I experimented. I cranked up a bass heavy song, tweeters definitely moved to the bass. I then unhooked the tweeter, reinstalled, no movement. That pretty much points to the crossover. I opened VCAD and found if I short the damping resistor and add one to the negative terminal of the tweeter it’d pretty much be the same FR and actually got a better phase alignment to the mid.
I tore one apart, modified, reassembled, cranked it up and the tweeter seems to be quite still now. Ditto to the other speaker. Live and learn.
Updated crossover…

Not to rub salt in a wound, but these didn’t place.. right? I’m still perplexed by that. Just seeing them I figured they were a shoe-in.. and hearing them convinced me they were very worthy.

In my thinking, he was def top 3. I don’t think I had Dan in the top 3, but maybe 4th.
In my location in the room, Eric’s were a bit thick in the midbass, however, did not have that same sound previously back in May.

Thanks guys. It’s always a crap shoot with how your speakers will be in whatever room. I definitely don’t voice my speakers flat, so that’s another thing. I’m sure the tweeter issue tanked my score a bit with Javad, no feelings hurt, wether Jerry or Andrew seen it too…
Par for the course with Dan winning
He knows how to make a speaker sing
Side note, my wife did say my speakers sounded different to her compared to the others. Like they were more subdued, or mellow/recessed.
Anyway, glad it was an “easy” fix, they still sound wonderful to me.

I heard nothing offensive at all. I assumed they were winners after the tracks were finished. Seemed pretty much in the bag.

Thanks Drew!
Honestly I thought they were good for the Fan Favorite, people really dig the baffles and all, again
Not sure how Juan or his wife won the fan fave the last 3 years in a row.
