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).
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.
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.
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.
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?
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.
