Not too excited about the 18k breakup. Also the 20W Pmax isn't too promising.
I don't hear anything above 15 khz if it isn't really loud. And even then a single tone spans a few kilohertz. If it's reasonably well behaved, might be interesting to hear what it does. (I'm not too keen on doing this with EQ)
Nobody 'hears' much after 15 kHz.
Problems in this area disturb 'air'.
Apparently that area ia called "presence" and enhancing it gives a feeling of hifi.
Probably bullshit. Who knows. Should be easy to kill it with eq if it's bothersome.
Air... Presence... well yes, even I believe in it, although I am now entirely unable to hear it. Feeling of hifi? I think that may be a bullshit description, but I wouldn't argue too much with something like feeling of being there. But this must be happening a bit lower than 15k, because, as Priidik says, most adults don't hear much above that anyway.
