I know it matters to some but choosing a JTR speaker and 95 or 101db doesn't sway me either way. But I know many on here do care about the 101db sensitivity.
Agreed that 95db is already high - higher than most speakers.
Here's my theory as to why 101db has real benefits...speculation here, so please step in if someone has real knowledge. I'm not sure that I'm right about this stuff.
I think that real live sound has lots of big dynamic peaks.
If you clip those peaks away, whether by running out of amp power, overdriving input or outputs, digital clipping, etc., it doesn't sound broken. You can hear heavy clipping, but just clipping of the peaks makes it lose that live, dynamic quality.
And fully getting those peaks takes a surprising combination of amp power and speaker efficiency. My 400 wpc amp + 101db 212HTs seems to do the job nicely.
95db would be just just as good with 1600 wpc amps.
