  • 94mm Faceplate Tweeters

    Hey guys,

    As some of you know, I acquired maynardg's Malbec cabinets recently. First thought is, I'll need way better tools and a lot more experience to ever hope to put cabinets like that together. Kudos, Maynard!

    Second thought: the tweeter cutout is 94mm, and I'm having a little difficulty finding a decent, reasonably priced, 94mm flange tweeter. I found a couple of Morels, the MDT29 and CAT378, but I've not heard of builds with these, so they might be a crapshoot. Still, if they're good they might fill the bill.

    So. Anyone have recommendations for good, relatively low cost (call it 75 bucks and down) 94mm flange tweeters? Links will be handy if you can provide them.


    Thanks in advance!

      Mark, before I forget, send me an email or something reminding me to dig through my stash, I may have something for you.

        Just a thought that any tweeter that you can change the face plate you could make your own face plate to fit. Dave Pellegrene probably has one for the RS28.

        You could always hot glue a block behind the opening an reroute the hole a few mm.

          I compared the Morel MDT29 to the RS28f, xt19, and SS HDS. It was the best of the lot to my ears.

            If you can xover high enough, the XT19 gets my vote.

              IIRC, Mark Kraweic's tests on the XT19 indicated crossing at 2.5 kHz was very doable (I don't remember what order he recommended, though). I also don't know how identical the current XT19 is to the one Mark tested quite a few years ago. In my cenTiLanas, Pete Schumacher crossed at ~3.2 kHz from the RS52.

                  It's still not an Usher or RS28, so that is my reasoning for saying what I did. I've always heard it was better 3k+.

                    Just so there's no misunderstanding, Wolf, I didn't quote you to mean I was disagreeing with you. Only wanted to share my knowledge and experience. I do question, though, if the current XT19 that's available is identical to the original version with respect to all performance abilities because the original one performed and sounded well above its "pay grade".

                      I just thought you were questioning my usage of 'xover high enough', so I clarified.
                      No disagreement was entertained.

                        I guess it's a matter of opinion, but being familiar with all of those drivers I would not put the MDT29 in the same class as the other tweeters you listed. The CAT308 I would though.

                          Agreed. There have been (still are?) several versions of the XT19 and it is important to know which one to consider. I have original XT19s from way back that have the 94mm faceplate, use the standard magnet, not neodymium, have the small chamber over the vent opening and are, I think, probably superior to the other versions. I tested and examined (i.e. destroyed) one of the smaller, cheaper ones. Not anything I would use at all.

                          That version of the XT19 is essentially the equivalent of the OW1 when crossed 3K LR2 IMO. I had to substitute the XT19s when the OW1s were blown while testing with the digital filter in an older version of SoundEasy and lived with them as replacement for quite some time.

                            I thought the mdt 29 was the same tweeter as the mdt30s with a smaller face plate but I stand corrected. It does have different specs and no rear chamber. sorry about the confusion.
