I had not thought of that. Thank you.
I can imagine that a better tweeter may not mean better sound, if both drivers were designed and integrated to go with each other. I suppose I could end up with an overly bright sound.
Anyhow, thanks for your feedback.
I probably should have asked what speaker in the 5k to 10k range be considered a decent upgrade to what I currently have.
Listen to a lot of Jazz and some classical. looking for smoother highs on the first, and a bigger sound (not louder, mind you) on the latter. Not a big room, so probably limited to small full range or good monitors.
