Question about replacing a tweeter

I

Hello,
I have a pair of Alesis M1 Active Mk2s, and the tweeter on one of them has finally broken. The replacement process itself is easy enough, I was troubleshooting to see if it was a fuse or the tweeter itself by switching between the two monitors, and came to find that soldering isn't even required. I then took to the internet with a part number (7-02-0028) and only eBay links popped up. I'm a complete amateur and am wondering if I have to go with this replica from Hong Kong or if I don't even have to comply with the part number and can stick any third party tweeter in.

Specs of the tweeter:
4 ohm
1"
94mm Diameter Cut-Off Hole
75mm Diameter
30 watt RMS Impedance
91 dB Sensitivity

Any and all tips are appreciated

Hello. That's a studio monitor, to keep it performing as it should, you should get the right part. Not any generic replacement.

If you are interested I can guide you to open the tweeter and check the voice coil. Sometimes you can unwind one turn and solder the wire again. Sometimes just soldering a wire bridge can restore the unit.

Yeah that sounds incredible. A walkthrough would be highly appreciated. I have a soldering iron but would I need any other tools?
 
Usually you need a philips screwdriver or allen wrench to remove the faceplate. Those 4 screws on the front of the tweeter. And a magnifier glass and small pliers or tweezers to do the repair if possible.

BE CAREFUL: THE MAGNET IS VERY STRONG AND WILL ATTRACT YOUR TOOLS AND THE SCREWS TO IT, DAMAGING THE DOME IF YOU DROP A TOOL OR A SCREW. HOLD EVERYTHING FIRMLY.

This is the only "difficult" thing you should find. Remove the tweeter from the speaker, measure resistance with a dmm to confirm it reads open, and if so, remove the 4 screws from the faceplate and remove the faceplate. Upload picts of both sides of the tweeter if you find any
difficulty.
 
If deciding to go new with a different tweeter.
Do both speakers with the same tweeter.

Then save back the good one until an orignal can be sourced later.
