RE: Klipsch KI-396-SMA-II . Wow - 101dB sensitivity with peaks of 133dB. This is a real "play to your neighborhood" type of speaker.
And 60-18kHz +- 3dB. Looks like they are not fudging the frequency response either.
I wonder if this could be used as a foghorn in the maritime regions.
Nope. Not without subwoofer assistance.
