    There was a bit of excess surround glue that stuck to one side of the faceplate but the faceplate didn't appear to be intentionally glued down, at least on the tweeter I opened. I'd imagine the surround could lift off the carrier if the faceplate was stuck to it all the way around.
    Yup, mine are stuck on "good", looking at it again using the grill I might be able to push down on it and set it free...
    If not the WG can be modded to work anyway.
    Guess xmax's age.

    My guess: 15. His grammar is passable. His trolling is good.

    • From this picture, it appears as though the voice coil leads are sandwiched between the carrier and the faceplate. Kinda strange

      • It's not all that strange. A lot of SS domes are done this way.

        • Some da25’s I cut down to get closer to the woofer. The plate seems to be aircraft aluminum. At first I thought it was steel because it’s very strong for its thinness. These will be rear mounted and a small wave guide to be done. Not sure if I’ll do a simple 45 degree chamfer or round over. I’ll have a spare test piece I was going to try both and see which is better.

          • According to the blurb from the manufacturer, they are steel faces.

            • I thought they were steel but my magnet does not stick to them. There must be enough of a magnet behind the face plate to hold the grill on.

              • Anybody have any measurements in a wave guide?

                • the faceplates are stainless steel, so that they can be thin enough to give the acoustic performance we are looking for, but still be strong enough,
                  and yes, there are no additional magnets holding the grille,

                  they work well in waveguides, these was designed to measure well in a totally flat thin faceplate, which means a (hard to achieve) raw response, as it's 'adjusted' by the faceplate/chamfer loading,
                  this flat raw response, means that you get a very honest performance in a waveguide, largely determined by the WG, rather than the anomalies of the TW FR + WG interaction.

                  • An easily removable face plate and nice flat mounting surface make this tweeter a no-brainer for waveguide application. If Tymphany had a factory made option, or even a pre-designed 3D printable model that would simplify things even further for the DIYer.

                    • I've got a waveguide printed out and just waiting for a replacement tweeter - i was careless and dented the dome on the one I had. PE lists new ones as shipping in November. I'll post results in my 3D printed waveguide thread.
