But a compression driver is basically a dome tweeter or midrange with a horn that provides the added efficiency, so it has power limitations if overpowered or hard clipping occurs. In a smaller room, headroom isn't hard to achieve. My speakers are 6-1/2" 2-1/2-way with Peerless woofers and Peerless or Vifa soft dome tweeters- they're not as sensitive as the Klipsch, but with the Parasound A24 power amp, SPL and headroom aren't a problem. However, my typical listening level is nowhere near 98dB because I value my hearing, which is much better than average for my age and even though I have been exposed to very high SPL in the past, I carry ear plugs wherever I go and that has allowed me to continue to work in the Audio/Video sales/installation/integration business for as long as I have since people who do this tend to have better credibility if they DON'T answer "Does this sound good?" with "Huh?".
I have cranked the level of my system, more for evaluation than general listening and it can really get up & go. I would argue that great speakers are more important than extreme sensitivity and SPL.
I have posted about it before- I went to a friends' higher-end audio store and while he set up some equipment, he had music playing at a low level. I walked closer to the speakers to listen for dispersion and frequency response, then asked if many people commented about the level of detail they heard at low SPL- he paused and said "come to think of it, they do".
Save your ears- if you want different sound, listen to more speakers. We only get one pair and when they go bad, they aren't replaceable.
BTW- bass makes the system sound louder- loudness isn't the same as intensity.
