I'm not sure what kind of "mods & tweaks" you're talking about, but if a Maggie transducer is slapping the only way to resolve it is to limit low frequencies and/or turn the volume down.

Well Davey, that works, also. It is not, however, the only way. If no one knows any better (which I truly doubt) I think I'll patent it then : - ))

C'mon, squeeze that brain cell past conventional engineering, be creative. You actually know how to do this.

  Spill it. Or is it a big secret? :)
  Creativity doesn't trump the laws of physics. :)

    No big secret but let me check the status of the patent-pendings : - )) Actually, if no one comes to bring it up, I'll explain more by the end of this month, when I get enough time to do it properly.
    
    For now, partial hints...things add up; synergistically.
    - Try increasing system efficiency (think beyond the obvious).
    - Also, include the normal human "perceptual space" (and even consider that measured SPL is not always perceived SPL).
    - Also, think back to your own MMGs before you framed them vs framed. (Did that alone not gain you some headroom in this direction?)
    - What about your PLLXO biamp setup. Ok, you may have not been pursuing "slap issues". However, I did exploit my PLLXO's potential in this direction also, simply because...oh, well, the damn 1812 cannons!
    - BTW, if you measure the REAL output of each MMG at various SPL levels, funny things may be observed that are key to this whole thing. (No electronic chart or formula will tell you this unless you have ALL the parameters, which not even Magnepan has. Then you need a Cray's help : - ))
    - The Maggies reality HAS to be measured in practice.
    - In addition, think about what improved clarity does to the whole thing. Again, it is a role that includes perception...but it can partially measured when one wants.
    - The role of proper amplification: some clipping can be confused for slapping. In addition, some amps can push more power/SPL before "real slap" happens. "Damping factor" may not be the explanation but something along those lines may be.
    
    Even before any mention of a woofer or subwoofer comes into play, a set of Maggies ALONE can avoid slap at higher SPL, both real and perceived. Which is why I only now began to add woofers even when the need for them has almost "not been there". (At low pipe organ notes I almost wish I had Slap from the MMGs, LOL! I do get it NOW from the new woofers if I go beyond their limits, but that a design sacrifice for better music, not ear-splitting SPL).
    
    So, you are correct: "Creativity doesn't trump the laws of physics. :)" Yet, the greatest engineering cannot uncover real opportunities if its attitude is not creative. Science is not negated or violated at all. It is simply more widely, fully and creatively applied.

      All hints/points that are irrelevant to "real" Maggie slap.
      
      In fact, I think a definition of "slap" would be a good thing to start with in your patent application. I define it simply as the transducer diaphragm making contact with the magnets behind. Maybe you have a different definition?
      Also, I'm not sure what "perceived" Maggie slap is. You might want to include an explanation of that in your patent application as well. :)
      
      Cheers,
      
      Dave.
