Binding Post Nuts for 80's Monitor Speaker

mgsimmer

Hi, I need 1 red and 1 black binding post nut for one of my recently acquired Monitor 7b speakers. The nuts from any of the 80s monitors should work. Please let me know if you have these. Thanks!

Most folks replace them with ones of higher quality, such as Cardas, WBT or Vampire.

mgsimmer

Thanks. I would like to keep these original and matched. Just need the black and red screw on nuts for one of the 2 speakers.

F1nut

Check eBay.

I believe Parts Express sells something close for like $2 or $3 a pair. They and the stock ones really are junk.

mgsimmer

I want to thank the forum member that mailed me these! I really do appreciate it. I have that junk screwed on and helping to deliver a spectacular 200WPC playing of "Money for Nothing" as I write this.

You can lead a horse to water, but............

Play nice, J.

Really? Are you trying to say that the brand of nuts on the binding post make an audible difference?

mgsimmer

Presuming the horse needed leading, he may hesitate if the water turned out to be snake oil.

That's a new one, "snake oil" in conductivity of metals.

As long as the OP is happy though, I'm sure he'll sleep ok.

mgsimmer

These aren't 15 amp circuits. The factory terminals are capable of conducting more than they'll ever need to.

There's a reason that electronics use gold silver and copper in their circuits, not just 15amp circuits

Glad you found your nuts...happy listening

mgsimmer

Yes there is, but it's not for any electrical, mechanical or sonic reason.

Gold is essential in computer circuitry because of its electrical
conductivity and because it does not degrade over time."

But it's a little more complicated than that.

As you already noted, silver is a better conductor of electricity.
The sigma of silver (electrical conductivity ratio) is 63010000
/ohm.m
compared to gold's sigma of 45210000 /ohm.m


Not only is silver a better conductor, according to Deringer Contacts,
a specialist in electrical contacts, silver can conduct higher levels
of current than gold:

"This group of materials exhibits the highest conductivity, both
electrical and thermal. . . Being better conductors, this group is
capable of carrying higher currents."

But in the end, gold still wins out. Why? Because most electronic
circuits do not use very high electrical current. And even though
gold is more expensive, the low surface area used keeps the cost down.
So in the end gold's resistance to corrosion makes it the more
cost-efficient material to use.

We're talking about speaker terminals that include enough material such that their conductivity is more than what is needed for use in this application.

Was the reference to the binding posts or the nuts? I thought the OP was just looking for nuts, not new binding posts. So again, I don't see where conductivity even comes into play.

Again...the op asked about nuts...not binding posts.

That would be like me asking for a spark plug for a V6 Camaro and someone recommending I buy the V8 engine instead.

No if it was a camaro we would suggest buying a premium spark plug for performance

mgsimmer

Needed nuts, not terminals. Replacing the terminals wouldn't get me a performance advantage.

trav0810

So that means you would recommend the best version of the part that I asked for. He asked for a nut for a binding post. Not a binding post. So again, this goes back to the original statement I made. Is there a difference from 1 binding post nut to another in Sonic quality?

txcoastal1

Like I said happy listening glad you found them...it was only a suggestion

"While you are changing the spark plugs new cables may be a good idea since you're under the hood"

Cheers

trav0810

That is exactly the kind of salesman speak I was talking about. Lol.

And if you're changing the wires, you might want some upgraded coil packs as well!

Damn...I was wanting to spend $5 on a plug, now I'm into a $500 upgrade!

They say ignorance is bliss, enjoy.

mgsimmer

LOL I'm glad you are in a state of bliss!

F1nut

Yes, thanks. It's much better than your state of ignorance.

trav0810

I've owned a couple dozen pairs of Polks and can't remember ever once sitting there and thinking "Damn...those binding posts sound like crap"

F1nut

And until you modded your crossovers you didn't think your speakers sounded like crap either.

trav0810

I disagree with that. I have had several pair of speakers that upon listening to them I determined they needed a recap. I have had several pairs that I immediately changed out the tweeters because I preferred the sound of the RDO. But I've yet to hook up a pair and go uggggh...those binding posts have got to go. Now, that being said, if you have done every other upgrade imaginable, then I am sure there maybe some measurable difference from the factory posts to something more high-end, but probably not something that most people would notice. You have to understand that not everyone is you, with your listening habits. Somebody that may have picked up a pair of vintage Polks at a yard sale for fifty bucks and is running them off of a 1987 Kenwood receiver might not be interested in upgrading those speakers, they may just be looking to replace a missing part.

I'd recommend the V8 LS swap on a V6 Camaro. Those things are dogs...
