Great how did the demo sound?
Absurd thought that because you can drive a $ 20K plus speaker with cheap electronics you would. As if this would be a reason to not make a speaker easy to drive.
Many of you are showing a fundamental misunderstanding of how most amps react to low impedance speakers. Low impedance is never a good thing. Yes can make a good sounding weird curve/high impedance speaker which sounds good, but why would you. You seem to think that enormous thought goes into every aspect of speaker design.
Remember that when David Wilson started building speakers, no tube options were available or at least in favor.
