Hi JohnK,
As a whole I agree with your statements about Large Hi sensitivity speakers, but your statements aren't entirely fair. I'll just take dyns... "You have to sit very close to smaller loudspeakers to reduce this if not music peaks will sound harsh" Yes, they are less sensitive and require some power, but dyn has a lower crossover point on most of its smaller speakers than most to make them completely listenable without it being a must for nearfield, I've listened to some great 6 1/2 inch from 12 feet away without issue, next "Thermal compression". These guys use 3" coils on their woofers and normally 1.25" coils on their tweeters and are quite capable of playing all frequencies with a fair amount of power without heating up and compressing frequencies. "Undersized Cabinets" & "Weak Magnets",
You know these drivers have Plenty of motor structure to do as designed and in proper cabinets to support their driver size and qts/vas capabilities....No, they won't compete with large high sensitve speakers in sheer dynamic range, but with the right amps are dynamic and smooth in their own right.
To the others, John makes some wonderful High Efficiency speakers, he knows his stuff, I just wanted a fair comparison.
