Binding posts Brass vs Copper : does really makes differences ?

That puzzles me, too. You have to specify diameter, material, finish, hole positions, threads... all parts of design. It's mechanical design, not electronics design, but it's design nonetheless.

I guess the difference there between me and you is that my finished xover would still have the euroblock terminals joining everything together. Mostly because I'm lazy.

(But on the back of the speaker, always a Speakon. If for no other reason except that our cleaning person can detach it, vacuum behind the speaker, and reattach it, without the slightest chance of flipping polarity, joining two poles together, etc.)

It's just a binding post, that's what I mean. It may be styled slightly differently from other commodity parts that do the same thing in the same way, with the plastic cap, but design requires a bit more than minor physical differences. It's like the difference between a 1955 Citroën DS-19 and a 1955 Chevy. The former is designed from top to bottom. The latter is merely styled so as to look different from the previous year's model.

Yeah, OK, whatever. Go make your own binding posts from scratch, pick an alloy, come up with a new grip shape and a logo to put on them and then tell the world how you "styled" them. I would say you designed them.

Maybe it's a language thing?

someone is mistaking design with engineer

None of that is industrial design, really. Except for the "grip shape," arguably.

But even that is more "styling" with a dollop "marketing" than "design."

Perhaps. Are you a non-native English speaker?

Pallas: it seems you are drawing lines where there are none, these relate to your own personal opinions/prejudice and have nothing to do with the definition of words.

It does seem that you are not understanding English correctly (this is being generous). Even if it were 99.9% styling and 0.1% engineering, it would be 100% designing.

I haven't read he whole thread, but I like copper, the corrosion thing is a non-issue with a quick application of Deoxit Gold.

I can't say for sure, but I have heard that Lanolin can do the same job *shrugs*

Inductor,
I would assume from looking just at the picture above of the binding post that they are spaced for standard banana plug distances. I know most people here would not think of using a banana plug but people still do that, it is convenient if you are disconnecting the connections for some particular reason often enough. That is why you see the small diameter hole in the center of the center portion. Just try and attach some of the ridiculous terminal ends on many of the so called audiophile cables, all the room in the world won't help with many of them.

I use bananas because I do swap out amps fairly often. I have fancy banana plugs that offer a tight fit.

Plus, I just like saying banana, banana, banana.

Pano,
I always space my binding posts for banana plugs. If someone wants to use them then they can without problems. I have never found that the spacing is to close to attach a cable to them if they are good enough to work and allow the binding post to tighten down on them. I have used some extremely costly cable ends that are a major pain in the rear, I won't name names but they would take a vise grip to tighten up on them..... I use banana plugs also when I am just doing a quick setup, so much more convenient. What I have heard but have not confirmed is that in the EU you can not use the correct spacing for an American dual banana plug standard as there are countries using ac power connectors with the same spacing. Anyone know about this fact or was that just a proposal?
