  1. The binding posts were bought from Parts Express. “Dayton Audio BPP-G Premium Binding Post Banana Jack Pair Gold - Part Number 091-620” My friend and his friend did the work with a milling machine. The holes had to be enlarged because the posts were a larger diameter than the Klipsch posts. They also cut a notch for the plastic to engage so the posts will not turn in the plates. The notch does not go all the way through the plate so there can be no air leak. (Probably wouldn’t be a problem because it would be real small and the speakers are ported and not sealed).
  2. Had to enlarge the holes for the larger diameter posts and cut notches for the plastic key to fit thereby locking the post in place so it doesn’t turn when tightening the speaker wires to the post.
  3. Thanks to an old friend with the right tools I think I have solved the issue.
  4. Persistence, connections, and help from a friend, and a friend of a friend.
  5. Well that is disappointing. I was thinking of buying that subwoofer to go with my Corn IV.
  6. That is the plan. New posts from Parts Express.
  7. The Klipsch binding posts are not deep enough for the banana plug to fully seat.
  8. Thread locker wont help. The plastic piece spins inside the hole in the input plate. The Klipsch plastic bushing / washer is smooth all the way around. Aftermarket posts have a key that locks into the keyway in the plate and keeps the post from spinning. The post is also squared off to lock into the bushing. The Klipsch is a perfect circle and smooth.
  9. A decent set of binding posts that will not spin when you tighten up the speaker wires. These type binding posts have a key that locks into a slot on the terminal plate that keeps it from spinning.
  10. Because the holes are too small and they are not keyed
  11. Anybody got some spare input plates for new Cornwalls or Heresies for sale? I think they are the same dimensions. Or do you have a 3D model of the plate so it can be printed?
  12. My source is a Luxman D-03X CD player and a Bluesound Vault 2i. The integrated amplifier is a Luxman L-509X. Interconnects and speaker wire are Clarus Aqua.
  13. I am thinking that you are correct and I may just put them back together and leave everything alone!
  14. The banana plugs are for jumpers. If I replace the binding posts, I will probably tie everything together on 2 posts instead of 4 and eliminate the jumpers.
  15. They are not keyed into the plates and they spin before the speaker wires are tightened sufficiently (in my opinion). They are also too shallow to fully seat a banana plug. The post inside the cabinet looks to be about a number 6 or 8 machine screw size.
  16. I have decided to not add any damping. I will trust the engineer knows more than I and they are voiced properly.
  17. I am replacing the binding posts. While inside the cabinet, I noticed lots of undamped space. I am tempted to add some 1/2" foam on the rear panel. But then again, I figure the panel was left uncovered for a reason. Has anyone added damping to a Cornwall IV, and if so, how did it turn out? Where did you add damping? What kind of material?
