Mirage M-1 tweeter died, No longer stock. Help

I bought a pair of m1's a year or so ago, off this board. Killer price of ~$360. Turned out three tweeters were blown. Found a guy who rebuilds them, and another who has perfect size match - titanium dome, not cloth. Fits right in the hole. I went with the latter, since the repair guy was too busy. I bought 4 new ATI tweets from LAB for roughly $400. The output level of the new tweets matched the remaining original, so for balance sake i replaced all four with titanium. Also the new ones didn't have the bar that pokes the grille cloth out. So, there was an aesthetic plus. I did have to change the lugs.

I just picked up a pair of M5si to match the M3si fronts in a HT rig and they also have 3 blown tweeters. Sent an e-mail to Chris at ABI to see if he can source the replacement parts for me. Great to see the M series are still making people happy.

I think the M-1 uses the same tweeter as the M-3. I purchased a pair of M-3's with both tweeters blown on the right channel. My speakers are the original M-3, not the M-3si. M-3 uses 8 ohm drivers, M-3si uses 4 ohm drivers. I couldn't find OEM replacements for my M-3's tweeters and was considering retrofitting with an Audax tweeter from Madisound when I stumbled across a listing on eBay for an Acoustic Research tweeter that vaguely looked similar to the M-3's tweeter.

The eBay seller only had one and didn't accept returns. However, I found the same model on Parts Express' website. The screw patterns looked similar and it looked like it had the same circuit-board flange mounted terminals of the OEM Mirage M-3 tweeter. On a hunch that the AR tweeter's plastic housing could be removed, I bought a pair.

It turns out that the plastic housing lifts right off when the 3 screws are removed, and below it is an exact replica of the M-3 tweeter, right down to the 2 dowel pins that align and pin the voice coil/dome assembly to the magnet structure. This entire tweeter bolts up to the M-3 tweeter housing using the same 3 screws. This replacement unit features a metalized dome, whereas the OEM unit is not metalized. Mechanically, this is a drop-in replacement. When installed, the speaker with the replacement tweeters sound exactly like the other channel with the OEM tweeters.Joy!

NGD Service in Montreal should have all the replacement parts for Mirage and quite a few other makes.  http://www.ndgservice.ca/parts_en.php?lang=en
