I hear/read a lot of discussion about modern Klipsch speakers and notice many people saying their sensitivity is overstated due to only the tweeter being horn loaded and the other drivers being small in comparison to the 12"/15" drivers on their classic high sensitivity speakers.

For example the KF-28 floorstander:

Its sensitivity is rated at 98dB @ 2.83V / 1m. Is this correct? If not then why and what is the correct sensitivity?

I have heard some say their sensitivity rating is somehow exaggerated but honestly...even if they are...they are easy to drive and get louder than I would ever listen them to...or frankly my neighbors 10 doors down would want me to play them.

If they are 96 sensitive rather than be it.

It may be, in the highs, where what's being measured is the horn loaded tweeter. In the lows, where sensitivity should be quoted, maybe. I say maybe as 2.83v into a 4 ohm load is 2 watts. That would give the speaker a 1m/1w sensitivity of 95dB, which is at the extreme end of what is possible. The average sensitivity of a pair of direct radiating woofers is 90dB 1w/1m. Higher sensitivity than that can be realized with pro-sound drivers, but they give up about an octave of low frequency extension to get that sensitivity.

Bottom line, if you don't see a measured SPL chart to back up sensitivity claims they should be taken with a grain of salt.
