Stainless Steel Binding posts on speakers?

I hear ya'. The reason I ask is Legacy uses SS for their binding posts on the Whisper XD's and stainless is rated VERY low in conductivity vs. copper and gold plated copper. Seems a very odd choice! This is a GREAT sounding speaker and I wonder how much better it COULD sound if a more 'industry standard' material were used?

I would guess that it doesn't make much difference. Resistance of binding post is most like in order of milliohms* while speaker is in ohms. For the Damping Factor, speaker impedance is mostly resistive and in addition there are inductors in series. Woofer inductor is most likely 0.1ohm. There might be other factors that affect the sound but not conductivity IMHO.

* - Binding post is in order of 0.4"dia corresponding to AWG000 wire. Copper wire AWG000 resistance is 0.2mohm per meter. Stainless Steel is 50x worse than copper but your post is also not longer than 2cm (1/50x1m). Result is under 1mohm.

Are you certain that it is stainless steel, and not a plated metal, like rhodium plated brass?

Martin Logan at one time offered Stainless Steel binding posts as a custom order option. IIRC, they were pretty damn expensive. I never heard a set, but always thought they were "supposed" to sound better? Makes me wonder...

Roxy54. Nope. Definitely not Rhodium plated brass. I have an extra one of them that was defective and took a 3 corner file to it to scratch the surface...same steel grey color inside. And the non-magnetic type. They are pretty things and very beefy, but definitely stainless steel.
