A friends B&W 802D2 has that sparkle I’m referring to as well. Ringing tweeter also?
If a driver cone sounds like the material it’s made of, as is the case with many speakers mentioned here, then yes (yeah, yeah, I'm well aware of cone breakup measurements...) I’ll call it "ringing" since that’s what it sounds like to my ears. You can call it "sparkle," but I believe what you’re hearing is the inherent properties of cone materials masquerading as extra detail. That’s great for selling speakers to home theater buffs, not so great for long term musical enjoyment.
