  1. Thanks John. I understand why Klipsch put caps on the upstream side of the autoformer!
  2. 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?
  3. 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.
  4. Yes, that sounds right. I bought some Lascalas from him.
  5. 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.
  6. 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.
  7. 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.
  8. 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.
  9. 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.
  10. 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.
