The torn inductor isn't ruined. In fact if you bypassed the torn section and connected the crossover wire there you'd be hard pressed to notice the difference in sound between the two speakers. IMO, with the length of foil in those inductors, two inches less shouldn't make an audible diff. If you want to be persnickety about it, shorten the length of the other inductor two inches as well.

Thanks guys! Yeah, there is only one capacitor and one inductor per speaker. I still haven't found the spec of the foil inductors yet. I will clean the foil and try hooking it back up! I'm not great at electrical stuff, but I'm learning. I think I'll be trying my hand in soldering the silver tweeter wires to the posts on the speakers, then running a small length of copper wire to the crossover boxes. I got the speakers with the boxes screwed into the back of the speaker, with the driver wires sticking into them.
Is that glue just normal silicon glue I can find at a hardware store? Should I just coat the electrical connections after soldering with the stuff to insulate? Is it to prevent anything touching them?
I tried one speaker last night. Not quite the shimmer as my 2.7's, but I probably need the other one running to get a better idea how they sound. There are two small sections where I'll use some Dap to eliminate a small gap. They were recently rewired and it looks pretty good. My 2.7's have a buzz in the lower registers, so I'm thinking the MG II's will help me prepare for tackling that project. It might save me $700 from sending them to Magnepan!
As said above, the inductors are an easy fix. The delamination should not be a big challenge either. Just don't use too much glue and try to prepare well and keep things as clean as you can while you work.
I don't really understand what the issue is with having the crossover boxes remain as they are if they are working and the speaker vibrations are not coloring sound from them. You can wedge in wood supports between the floor and the boxes to dampen the vibrations. Styrofoam blocks would work too. .
Right! I'll keep them in the system, as I don't think they'll fit in the back of the speaker anyway. I just wasn't sure if I should try to go back to stock cheaper equipment if my current aftermarket stuff is shot. Either way, I'll use the boxes as they look pretty nice. Thanks!
