  1. The kappalite 3015lf4 is a 12” woofer. If doing a cornscala you need 15”. So, Buy a 15” from bob crites. He has 2 very good choices or get a eminence Kappa 15C from parts express.
  2. Are you discussing a cornscala or super heresy. The 15c is a suggestion for a cornscala. I believe the original post is about building a cornscala. He was showing his previous efforts with the super Heresy.
  3. The universals are 6db filters and don’t have same issue. I’d want a specific woofer then the cornscalawal but I’d want higher older filters... need to be kliapxh compatible with k33 or 15C
  4. If I can make 2 suggestions. ALK ES and AP12 networks expect to see a predicted inductance of the voice coil. Meaning that it’s set for a K33/K43 woofer. The Kappa 15C has been measured by Al and is also compatible. If you use something different the crossover could not be expected to perform as predicted. Maybe it wouldn’t matter. Al and only a handful of other people can do the level of calculations needed. In short, use a k33 or kappa 15C or ask Al. Secondly, the DE85 is lovely, is perfect especially for this application. That said. The DE750 was a monster. Bass was much improved. It’s the same diaphragm but 2x the magnet.
  5. They really sound fantastic. Less bass then the cornscala imaging and tonal balance is incredible. Think Dynaco A25/Devore O93. At this point Id say the cornscalaa and the AN15 are my 2best speakers. Big but not huge and incredibly impressive.
  6. Yes it was worth it. Special thanks to Dave Harris for the design and baffles. My cornscala is a truer to source output but these sound like music. I would easily place them on par with my cornscalas. Though I built both and didn’t skimp at all. I would say the cornscala is still more stoutly made. If You ever get a chance to hear the 15 take it upon yourself. I’ve had the 8 inch and heard the 10, but neither compare to the scale and detail and ease the 15 provides.
  7. Thats sooooo stupid... The LED should turn on when charging. It has charged... but I didnt know I could turn off and still charge... thanks for the information, super helpful. I took your advise and just reversed them.
  8. I have my done... Sounds good. Only curious aspect is that you have to have it "On" for it to charge.
  9. I’m not the same Justin. That said, been building SET amps and modifying Klipisch speakers for 20 years. Given that I’m 40, means I’ve been at it for a tinny but of time ;-). On all the forums I’ve always used my full name or company name. I don’t like aviators which sometimes hide identity. If you guys want some more shots of the Cit V let me know. It’s interesting. I’m getting 32watts rms with the 7581a and tube rectification but it’s very very wide bandwidth. I think the bandwidth makes amp sound much more powerful.
  10. Ive used Pi3s with Roppiee for a roon bridge. You can add a DAC hat if you dont have a dac already. With Roopie XL you can also use as Airplay end point. Trying the Pi4 ive had compatibility issues with my DAC. I might just add a HAT to fix and bypass the DAC.
  11. The magic of the HK designs are that the transformers are relatively common. HK, complicated circuits... basic iron... UL for Cit II and Non UL for Cit 5. Macintosh... simple circuits, complex transformers. Its very difficult to duplicate Mac Iron... HK outputs can me made for any number of great suppliers.
  12. The last step it to make our own customer transformer covers. Ill try to laser etch the bias instructions... I figure Ill never have to search out the instructions that way.
