I can't give any technical answer since I'm not a technical guy. I will say that Terry DeWick and Drew Bolce came over to my house (in Knoxville) once to hear them. They brought some of their testing gear. From a chart perspective, in the home, my hearing stopped somewhere around 14K as I recall (I know, not very scientific but it's a yardstick). The graph continued up to roughly 18K AND, very interesting to me, was "ruler" flat. I do'nt know what scale they were using but it was amazing to me how flat the line was.
I didn't hear squat in the room though. Too high for my tired ears.
That said, the Jubilee in stock form, uses the 2" K69 driver that is the tweeter driver in the cinema lineup. Since it's 2" I guess you get more ability, more mouth area (or something like that) and lower distortion than a smaller driver running at the same SPL's.
These things however, are on cruise control in the home. Do some math.... 109 db @ 1 watt? ouch.
When the meter on my McIntosh amp (biamped at the time, running my HF horn) was peaking between 5/10 watts, things were toe tapping. If it got to peaking around 25 watts, the wife would be asking me to turnnnnnnnnnnnnn ittttttttttttttt downnnnnnnnnnnnn
