Atma notes above
This went unnoticed; how many low sensitivity spkrs can actually produce 20dB dynamic contrast starting from an audible minimum level? Answer: very few if any. Just do the math, the drivers will quick the bucket.
So for beauty, choose dynamic spkrs; for concert dynamics, it's only horns.
20db BTW is a 100:1 difference in power.by which cryptic remark, he means: it takes one HUNDRED TIMES the power to yield an increase of 20dB in spl. (Btw 20dB in spl is 10x louder.)
