Yes. Putting a component on one side or the other can change the size and probably the cost of that component due to the impedance it operates in to.
Thanks John. I understand why Klipsch put caps on the upstream side of the autoformer!

Yes.
Thanks

Klipsch historically designed crossovers with a cap feeding an autoformer and then a coil parallel to the driver (like the mid on the Cornwall II for example)
Are those true second order crossovers?

I actually learned about his passing here. He introduced me to Dave. I have no additional information about DJK’s death. Some great memories from the Audio Room days though. He could make anything: better, faster, tougher.
I was an engineer at Rockwell and left in 2011.

Yes, that sounds right. I bought some Lascalas from him.

I got to hear these in a custom pair of belles at one of DJK’s friend’s place. Very articulate. I too never really questioned his suggestions or recollection of specs.

With the 8 ohm HF146, I’m taking 10-11db off with the crites 3636 autoformer and I think I prefer the AMT more forward, like nearly at the front edge. I’m guessing that’s because the AMTs sound better a little farther from the back wall.
If pinpoint imagery was my #1 priority it’d be hard to best these guys in 2 way.
OCD sucks.

Look great, bet they sound better. Any thoughts of an active crossover down the road? You can try endless combos anytime you want.
Thanks. I did this project with the goal of passive crossover unless I absolutely needed to go active. As Glens suggested, my OCD would mean I might melt down with so many options. But they sound so good now I’m thinking I can stay passive. I think.

Very nice. Cool "Wizard of Oz" curtain hiding the equipment...........
Shakey
I had Cornwalls in those corners before and I used my curtains to hide the TV per Chris’ advice. I don’t really need them with these guys. But that window does face West so yes, it’s good to keep the evening sun out of my eyes.

Nice work! Any plans for grills?
Yes. I had the cabinet maker make me some. They are 1/2” baltic birch! Ha. I will get cloth on them and see how they work.

My work on my new speakers is not over, still a little more fine tuning. They may be considered sort of a Cornscala E? These guys are capable of two way and three way operation. I’d remove the center spacer if I wanted to keep it 3 way and I’m leaning that way. The cab is designed for F3 of 39HZ, they are roughly 99db/w/m and use second order Bessel crossovers at 600/3.5k. I have changed a couple things from the straight calculation but man it sounds really good. I am not quite certain on placement on the AMT, but over the center of the Faital Pro comp driver sounds right.
Some of my audiophile buddies showed up for a four hour marathon listening session last night. That was super fun.
I am very unsophisticated with respect to cabinetry, amongst other things so, I had them built and I gleaned crossover tips from scouring countless threads and using crossover calculators.
I have dubbed these “That 70s Speaker” for their slight and intentional resemblance to the Altec M19s and use of the ESS AMT in the three way config.

Thanks guys. Yes, I mean the grill itself.

It’s a plastic something or other. I would like to buy some similar material.

UPDATE
I have been fooling around with various xover networks and have found, to my ears at least, that a 2nd order Bessel with a Zobel across the woofer works best, if fact it opens up the AMT and helps it blend better with the woofer (Crites woofer). Still you may need to move the AMT around the top of the Corn box to get the best alignment for you room. It is an amazing combination
all the best
Ok, 800hz 2nd Bessel. I have a box of inductors and caps and it’s way too cold to play outside today.

What frequency are you crossing at?

What did you do with the ferrofluid in your k79k's?
Clean the slot out somehow? If so what did you use?
Just drop in the new TI's?
Clean out and replace the ferrofluid?
Any idea of the oil used by Klipsch for the carrier of the iron particles?
I cleaned the magnet but there wasn’t really any ferrofluid in mine.

Just did the same thing in my KP250's and Cornwall 2's and the difference is staggering, IMHO
I find it amazing how much of a game-changer a tweeter improvement is.

My apologies. This should serve as a PSA for old guys to not respond to a topic before drinking coffee and without reading glasses!

When you do open them up, open both. Go to the crossover terminal strip and loosen all of the screws. Spray a little electrical cleaner on the screws, make sure all of the wires are securely connected, nothing touching another, then tighten the screws back again. Cheap and easy troubleshooting.
If that doesn't work, new caps/crossovers are probably in order. Replace in both speakers.
Jimbo, if he has Cornwall IIs he won’t have terminal strips. He’ll see this...
