Unsound, with respect to
IMO the issue is one of how relaxed the sound is. Its been my experience that the system should lack the quality of 'being loud' and instead should seem to not sound very loud, even when (by most audiophile standards) it is. It is a fact that electronic reproducers tend to add artificial loudness cues to the sound, making it hard to sit in the room when peaks are hitting 100db. But an orchestra can hit 120 db peaks so it seems to me that if a system is able to do that without stress or strain (IOW it is **relaxed**) at such volumes, then we would be far more likely to play the system at higher volumes.
One of the first things I noticed upon installing a horn system (Classic Audio Loudspeakers) was the simple fact that without any particular intention, we tended to play the system at much higher sound pressures than we had done with the previous dynamic speaker, **even though we had the power to play the dynamic speaker at higher volumes**. This simple fact of the matter was the horns didn't **sound** loud, even though they were in fact playing louder.
This is why I make such a big deal about loudness cues. Making sure they are not distorted by the playback system IMO/IME separates the wheat from the chaff.
Even without things like vented baskets, and ferrofluid cooling, dynamic tweeters are typically capable of providing more than enough volume for typical rooms.
