Title: Attach binding posts to old speakers ?
Post by Sam S on 11/29/22 at 21:35:14

I recently bought these old 12 inch full range Zenith console drivers from a local on Craigslist.

I am trying to find out a good method to attach binding posts to either the speaker basket or the back plate just behind the alnico magnet.
Those two pins for positive and negative connection are about 3/4 inch long.
I am planning to solder some Cardas chassis wire to those pins and then connect to some Cardas binding posts.

But I am a total amateur and don't know if drilling holes for the binding posts anywhere on the speaker is a good idea?
I will eventually be mounting them in a Caintuck style baffle.

I don't think you want to drill into the motor structure or the frame here. Soldering to the pins seems correct, though, and you could run the cable to the base of the open baffle. That's where I would place connectors, with the pins facing the ground and whatever terminal you choose on the baffle base.
Or, you could use a foam adhesive mount cable tie pad on the magnet guard as a strain relief.

I've always used "pig tails" (short wire) soldered ONCE to the speaker with the other end soldered multiple times to where ever you want the speaker connected to. If possible, provide some sort of strain relief...I'll usually just hot melt glue or zip tie the pig tail wire to the speaker frame.

After looking at the photo, I agree with Ed about soldering a wire to a place where binding posts could be mounted on the speaker cabinet. I have redone speaker connectors before on a set of Audio Nirvana drivers that used odd sized banana binding posts. It was a good deal of work to make something that was sturdy and good looking at the same time.
