Replacing the binding posts at Magnepan 1,7i


I have bought Cardas CCGR-S binding posts to replace the originals at my Meggie's 1,7i

The hole at original binding posts insulator are too small.

How best to solve that out technically?

Please help I do not want to do any nonsense.

Yes, they are secured to the plate with rear-mounted hex nuts also!

With which tool did you remove the stock insulator? It is fix well to the rear plate. I am affraid to demage the graphic on the rear plate. Did you connect wire direct to the Cardas post with soldering or did you enlarge the original O connector too and fix it to the Cardas post?

Yep, I very slightly enlarged the holes in the speaker’s rear plate. On my Tympanis, the hex-shaped Magnepan connectors are secured to the plate with rear-mounted hex nuts; aren’t yours?

Yes, I removed the stock insulator and put the Cardas black plastic mounting block in it’s place. It is the short "nubs" on the backside of the Cardas block that are slightly larger than the stock holes in the Maggie plate. Though the Cardas binding posts are usable without the Cardas mounting block, it’s advisable to install the block as it prevents the posts from spinning when tightened.

bdp24,

You enlarged only holes in the plates.? What about holes in the stock post insulator? Did you remove stock one and replace it with Cardas post insulator? How to remove stock post insulator not to demaged the plate?


The holes are SO close to being big enough for the Cardas posts (the holes are just a hair too small) that a small round hand file run around the hole perimeters for a few minutes will take off enough metal. I enlarged the holes in the plates of my Tympani T-IVa that way. If you ever want to reinstall the stock Maggie connectors, the holes still allow that, no harm done.
