So far I'm not impressed with the tweeter.

I guess titanium tweeters are not my bag. Hardly any Soundstage and clarity/treble is good, but flat sounding. Center vocal imaging is good though and slightly hollowed. These well are more suited for their intentions background. For $25 they are OK. These can't replace my beloved Boston. Hells no. Diana Krall & Fiona Apple who have superb SQ recording sounded dull. The Journey continues. Maybe a better tweeter could save these as a DIY. Thoughts? I used it without a sub and with it on. Didn't make a difference.
