Rated 5 out of 5 by from Replace the domes/coilsReplaced the tweeter (MDT30) domes/coils on a pair of Esper Signals speakers and it was well worth it. The job was easy and the speakers are back to sounding like they should. Esper Signals is a Canadian speaker company that unfortunately didn't survive. Very well built and sweet sounding speakers.

Rated 5 out of 5 by from very nice, but....I bought a pair of Morel MDT30 tweeters back in the 80s. The domes have lost their shape and collected dust, so I was happy to see this replacement done available. But when I went to install them, I found that the three mounting holes for the screws to pass through are must allow three metal shaft/spacers on the faceplate to pass through, which they do not. The holes on the new replacement dome plastic surround are too small. I had to drill them out with a 1/4" bit to make it work. The plastic drilled easily, and then the new dome slide in with a little persuasion. Not too hard, but more involved than I thought. Then solder on the new wires and your all set. They look much better than the old worn out domes, and I do believe they sound nicer too. Would definitely recommend, but with the knowledge that, perhaps depending on the model or year, you may have to modify by some drilling to make them work.

Rated 5 out of 5 by from Looks like OEM Morel, but with a centering ringHand treated damping just like the originals.Unfortunately, it's impossible to accurately review their sound right now. Ask again after they break in :)

Morel R-30 Replacement Dome for CAT308 MDT30 DMS30

Will this fit on my Morel st728? And if not, which dome would fit?

Asked by: Caleb1836
Unfortunately that tweeter model is not listed so I cannot say if it will work or not. We do not have a diaphragm for that specific tweeter available.
