High treble speakers

[SAPSEC]

I love to hear high treble sound. Should I choose speakers having response > 30 Khz ?
Will I get more treble & crisp if this number is higher ?

There's a difference between an extended range and a peaked high end.

Not necessarily. The human ear cannot hear above 20khz at best. So your 30khz are pretty pointless. If you want good and crisp treble, you want to look exclusively at the tweeter you're wishing to purchase.. Not all tweeters sound the same, and some you will obviously prefer.
The specs don't really have a huge impact on how they sound. It's more the composition of it that will matter most, i.e the materials used in it that give certain sound caracteristics to each tweeter. Then again I am not a tweeter specialist..
