Hi!
For my next project I'm playing with the idea to make a bullet-type tweeter. The tweeter I bought (SB19-ST from SB accoustics) comes attached to a mounting plate but it seems to be easy to take that small 'baffle' of.
Are there any reasons not to do that sound-quality wise?
Kind regards,
Reinhout

I think it would be helpful to provide an image of the tweeter. https://www.falconacoustics.co.uk/downloads/SBA/SB19ST-C000-4.pdf

Souldn’t make a big difference sonically (as long as adequatly replaced), but the diaphragm/voice coil assemly will no longer be held down )so be careful). Thes eare removable to allow replacement if you burn the tweter out.

I think the small waveguide in the faceplate most likely has an effect on the directivity and frequency response, how much is impossible to tell until you measure before/after.
If you can replicate the shape of the faceplate in your baffle(?) it should be back to normal.

If you want to make a bullet tweeter you are better off with something like this or those from Vifa or Peerless.

The waveguide/roundover in the faceplate will definitely make a huge difference to the frequency response. Even 1mm difference in the thickness of the faceplate will result in a significant change.
A lot of tweeters with plastic face plates are very sensitive to how the diaphragm is clamped down to the motor, and molded features in the faceplate may help with centering. If you get this wrong, the voicecoil will rub and buzz.
I assume by 'bullet tweeter' you mean a teardrop tweeter which sits on top of a conventional cabinet. If that is the goal, why not start with a more compact tweeter? Peerless OX20SC00-04 comes to mind.

I bought these tweeters because I thought they matched well with the Dayton rs180. Now I'm on to the next phase..Coming up with a design.
I don't want to end up with just another bookshelf so I thought of putting the rs180 in a cube with a sort of bullet (one that looks like it was a vintage bicycle lamp) on top of it. Still open for some other ideas though!
