When you want to test your tweeters air and extension, what type of music or intruments are you looking for.
Thanks!

Thanks everyone ! Really appreciate all the great recs.
I love Dead can dance. I have most of their CDs .
I do like jazz,blue grass,folk,alt country,rock
Would female opera singers be a good test as well?

Thanks again for all the recommendations.
Now that I have a few cd's to look into, is there one or two SACD's that really work out a speakers tweeter. The whole SACD must be great as well, not just a track or two.
Appreciate all the contributions!
