cheap big binding posts for metal chassis

cyclecamper · 2nd December 2011, 05:49 PM

I have another thread on this in the parts forum, but people building amps are really the ones I want to ask.
need binding posts for #4 wire, mount on steel plate

What do you use for an affordable (cheap!) binding post that takes large #4 wire and mounts insulated from a metal chassis? I can't find 'em... I'm using them on steel plates on a bunch of bi-wired speakers, so I don't want to spend thousands of dollars on Mundorf parts.

If the #4 guage requirement is the problem I might consider a little smaller.

What I'm finding cost more than the drivers did.

I can't answer your question, but I have a wild idea. Why use steel plates to mount them? You do say that it is inside a speaker cabinet. If you mount them on a piece of wood, you can use any old cheap nuts and bolts as mounting posts. Just a thought.

McMaster-Carr

Has hex bar stock. You can drill a few holes and make your own speaker terminals!

Yes, on previous systems I just put huge brass bolts thru the cabinet with brass double locknuts and a brass wingnut. From McMaster-Carr.

I already have the cabinets cut for the plates, which are mostly to mount the Neutrik connectors.

When I use them at home I like to use my heavy flat oxygen-free cables. When I'm out I plan to use round cord with a Neutrik, but thought the binding posts might still be handy to wire the driver banks in parallel so the 4-conector Neutrik would work with a 2-conductor neutrik cable too.

For now I might just throw them together and use the Neutriks.

What size is ~4 wire?
4mm diameter or 5mm diameter or even inches would help.

I know that cheap 5way binding posts are available in 4mm size and there are a few 5mm versions.

By cheap I mean "inexpensive" but very functional and durable. I'm bulding mulitple subs, and it's a bit frustrating that the cabinet hardware doubles the cost. If I need 16 binding posts, I can't afford $100 Mundorf terminal posts; IMHO they should not cost 3 times as much as the drivers.

I have no idea what the average dimensions of #4 wire are, that's just what some "Unavailable/backordered" ones claimed, and I think my home wire is probably more like #10 anyway; I'd just like BIG strong terminals.
