  2. Conrad Johnson or Mcintosh

    MA2275 :-). My not a fan of CJ but love Mcintosh gear. Better built in my opinion.

    Where do you live? Close to LA? If so I can look at it. Criag of NOS valves could too if he is closer. Either way, we can pop the top and figure out whats going on.
  6. Cornscala help

    I can’t comment on Bobs woofer, except to say it’s very very well regarded. I’d say that looking at the Eminence 15c for simulations may help. In my experience the cabinet is too large. Shrinking the cab from ~6.5fu to 5.8cu should yield a faster, less flabby bass. I have never changed the ports dramatically. If I recall it’s 50sq in? moving the woofer up in cabinet may change things a bit (less baffle reinforcement?) but then again it might improve mid bass for you.
  7. Jubs clones gets top hats

    K69 were made by P.audio. If now made by B&C that’s great. B&C makes nice stuff.
  8. Jubs clones gets top hats

    Thats great info. Does Klipsch still par the K402 with the K69? Is the K69 still a P.Audio? I heard there were some changes to the driver at one point?
  9. Preamp Owners....What Are You Using?

    I have the same one.
  10. Jubs clones gets top hats

    I’ve only heard a 402 as active. I do know they are some anomalies hat are addressed in EQing. The pro guys could answer... I wouldn’t know. I’m a passive guy. I like not having active and the polars on the eliptrac don’t require eq. Does JWC or DrWho have their old measurements? Subjectively, was the K402 a bigger sound, Yes! was the eliptrac a perfectly balanced sound, yes I thought so. More so then when used in my own cornscalas based projects. The Eliptrac was monsteriously large in my room. I’m sure in larger rooms the k402 would have been a better choice. Perhaps a Jub bass bin and K510 vs Jub bass bin and eliptrac would be a better compairiaon?
  11. Jubs clones gets top hats

    I’ve heard both. I have my own thoughts but let’s get some measurements. ;-). The 402 may sound bigger but the 402 needs Eq.
  12. Jubs clones gets top hats

    I didn’t initially. Didn’t think an issue. I described them as such in the narrative. Took them on as a rehab project. Although the IP for the Jub bass bin is not protected, I am not and was not trying to infringe. I do think these modifications are pretty amazing and helped to complete my speaker. ALK now offers are redone/ revisited Jub ESN. The HF extension is pretty remarkable with it. Maybe someone with real Jubs will pair them up and we can hear it matted to the big 402 horn. I’d love to see the polars for both overplayed. That would be fun. I suspect the eliptrac wins on Hf ext with the passive nexteork.
  13. Sold - Jubilee Clones -

    Price drop $3300. Firm at that number. But think it’s an insane deal.
  14. Sold - Jubilee Clones -

    I had thought Id buck the trend... appears gravity does pull downward... not to please to know it. In rare occasions she had a point :-(.
  15. Sold - Jubilee Clones -

    I still will own 2 pair of cornscalas and 1 pair of heresys. But the jubs really don't fit in my SoCal home. My Royals (JWC punch based are in my studio for the Co. The Jubs are the best I've heard but just to monsterious. Now I know. There is a size limit. Didn't think so before.
