I suggested stronger magnets YEARS ago and was met with crickets.

You could, with such magnets increase the pole piece / driver spacing a little......still gain some sensitivity while lower chances of bottoming out.....

You MUST replace those refrigerator magnets with something of greater flux density.
But ALSO must be careful. VERY strong magnets can be dangerous. Everthing from a pinch event to stuff 'sticking'. Neo matnets are also brittle so you have THAT to look forward to...

between parts, fabrication and training, costs would go up...

Well, the reason your suggestion was met with crickets should have been obvious. All of those stronger magnets are darn expensive AND they come from the country with the big "C" in its name.

If I were Magnepan, I wouldn't go that direction either.

  One other minor point?
  
  Magnepan conventional wisdom is More good Watts = Better. I can't argue with that except my needs are more modest and with an A23 Parasound per panel....which is 200x2 I don't ever come close to tapping out my amps.. These amps play as loud or louder than the PSAudio I had years ago with 500x2 4ohm watts. It was a 'D' amp.
  
  But what IF a panel were an honest 3db more sensitive? Or 6db? Required amp power drops and the cost of a system may stay the same....More for the speakers? LESS for the amp. This cuts into running expenses, too. Especially for the Tube guy who may need output tubes replaced.
  
  Let's say my 'new' panels are over 3db more sensitive than my 1.6s? I would need only 1 amp, not that pair I now have. Savings? About 1000$ at retail for the amp. Could an 'improved' 1.6 gone more than 1000$ more than what I paid for 'em?

  Actually, my suggestion which has never been reacted to by anyone is that
  Magnepan establish a 'Custom Shop'....modeled after say.....Colt Firearms......
  You could get many Colt firearms rebuilt / detailed AND engraved. All are $$ and ALL are collectible.
  
  My suggestion to Magnepan? Get an EXPERT woodworker / help and proper shop tools. Sell CUSTOM wood framed panels built essentially TO SPEC. A few other things got tossed in, too, but that's the 'nut' of it....
  
  Stronger Magnets are in some ways Hazardous. And China is NOT the only source for 'em......the US, for example has rare earth deposits, too.....
  But you would require changes AT Magnepan. Pinch injuries with Uber Powerful magnets are possible. They STICK to one-another like stuck with CrazyGlue. You simply Can't screw that up.
  You would need proper tooling to handle and assemble a pole piece.... This would not be a trivial investment and may short-term slow down production.

    A custom shop? :)
    
    Magnepan is back-logged for months just trying to supply demand for their 'normal' products. I don't really know the inner business workings of the
    company, but I suspect a grandiose plan like that would partition the company into insolvency almost immediately. Concentrating on core competency, primarily, should be their objective. IMHO.

      I get it and understand 'core competency'....
      They'd continue making the SAME drivers in the same manner as now.
      
      The object is a Vallue Added reframe build which at first may offer only 2 or 3 woods. It would require ONLY a small shop. Maybe 500sqft to 600sqft. That is? 20x25 or 20x30. You'd need some tooling which can be Leased.
      
      Magnepan works on the 'wear many hats' model, if I know my manufacturing. You may have a dedicated shipping / receiveing 'group' but production must be flexible and willing to work any number of stations. I am 100% certain that opportunities exist to cut costs and increase production without adversly effecting quality or output. I did that kind of thing for a living for 20 years.
      In the long run? Quality IS free, just like the book title.
      
      If they are at capacity and any deviation from keeping the boat bailed out results in insolvency? Somebody needs to reevaluate the business model. I'd like to know some things. Like scrap rate? Rework rate? Employee turnover? I'd like to see the quality program data. I'd go into the company and pretend to be an ISO Auditor. I was thru bunches of them over the years and got pretty good at it. I could care less about stuff like the 'organizational chart' which is nearly meaningless. How does stuff REALLY get decided? Are they running 24-7 or 2 shifts or ???
      
      Nothing but opportunity.
