Do you mean you are using the DTK 30 with the MB Quart Q series crossover? I was thinking about getting
the PTK-40 tweeters, I think these are better than the DTK 30 series.
Thanks for the advice guys. I currently running the Polyglass VR165 tweeters, I thought it sounded a bit harsh and not enough crisp highs. Not sure if the TN52 tweeters are any difference.
