I have a pair of the old Alpine DDDrive tweeters (biodyna inverted domes) along with the pair of clear crossovers, from the DDC-R17A component set, at one time I believe Alpine's flagship set. Unfortunately, I don't have the mids.
How good are these tweeters? How would they compare to say, a DLS UR1 tweeter, or Quart tweeter? What are they worth? Any info appreciated.... Thanks!
