Beston RT003C Round Ribbon Tweeter
Removal of bezel / horn / phase plug possible / beneficial?
This is one of only a few small round planar tweeters, and at least on paper, offers the smoothest response. I'd love to use this to replace the roughly 1.4in outer diameter tweeter in a BMW automotive application, if it would survive a bezel/horn-ectomy. Anyone have any idea how removing the plastic phase plug and entire horn-like bezel would effect the response and dispersion? Might the mild horn loading and phase plug be responsible for the flat response vs other similar round planars? (SLS PRD100, apexjr buyout round planar) I only ask because a couple reviewers here reported excellent results removing the planar driver itself from a couple other models of semi-horn-loaded planar tweeters.
This tweeter is assembled with adhesive so removal of any specific part like this will be very difficult and likely not beneficial at all. The phase plug is likely attached to the center of the diaphragm and removal of this would be nearly impossible without damaging the diaphragm.

What would a crossover look like for using this Beston tweeter as a stand alone SUPER Tweeter?
You're the expert but I was thinking of crossing it at 8 or 9 KHZ. Would that work or do you have a better suggestion? From what little info I could find, I was also thinking going with a 3-way (-18khz). Can you find out or help narrow this down? I think a lot of folks out there may find this helpful for building a inexpensive Super Tweeter since this tweeter goes up to 40khz - right? I am wide open to any further details or helpful information on this - thanks! TW
You will need a 1.5 uF cap and .25 mH coil for an 8kHz crossover frequency.
