Copper vs. aluminium is also a matter of moving mass. For a given resistance, it doubles for copper and it will be a stupid solution for high frequency reproduction.

aluminum ,,,,,, tell me how that works out for you

actually I can tell you - it sounds like crap - same thing with electro planar speakers ribbons

  You're saying that aluminum speaker cables sound like crap?
  
  So you've tried speaker cables made out of crap and they sound like aluminum?

    If you substituted 10 gauge aluminum wire for 12 gauge copper wire to connect speakers, assuming a 2 to 3 meter cable length, there would be no detectible difference in sound as the resistance capacitance and inductance of the cables would be essentially the same at audio frequencies.
    
    Of course you might BELIEVE you hear a difference, but that is not the same as there actually being a difference in the sound.
    
    With a blind listening test, you would not be able to tell the difference.

      I am disagreeing with you on this, not to start trouble BTW. Difference will be detectable depending on system resolution. I tried many times to like the VH Audio aluminum foil caps when they first came out and have at least 500 hours on them, yuck. Now they sell the copper ones which are identical except for the foil. Good for a dull tube system however.
      
      Vast differences just from that. Both have Teflon dielectric and are identical AFAIK.

        He made an objective statement that is correct.
        Aluminum has approximately 1.5 times the resistivity of copper per unit area. There shouldn't be any debate about that.
        
        When you claim "vast differences" noted during subjective evaluation, you've ventured into a completely different realm. That is a classic audiophile straw man argument.

        the same as aluminum ? Maybe there are subtle variations that could have an effect on how the speakers sound.
        
        And let me make sure I don't mis understand you :
        
        you are saying that Aluminum wires, interconnects etc sound just the same - at a greatly reduced cost than pure copper interconnects and speaker wire ?

        He morphed the conversation from transducers to speaker wire and crossover components. You caught that, didn't you?

        And that material, as has been pointed out ad nauseam, is Al.
        Again, don't you think that Magnepan has tested/investigated all this?

        A subjective evaluation of his premise is perfectly within your capability. Two sets of speaker cables (copper and aluminum) with the same LCR characteristics can easily be sourced.
        If you can blind test those and do better than 50/50, report back.
        
        Anyways, the comedian's original post was regarding the musicality of copper versus aluminum in a 'transducer' application. Quite a different topic.

        I'm still waiting for an explanation why copper is more "musical" than aluminum, and why your aluminum LRS's don't sound like crap.
        Hopefully that's not too bossy for your sensitive audiophile noodle. :)
