Greetings!
Recently I picked up a pair of Acoustic Research M.5 Holographic Imaging speakers from the thrift shop. Now one of them was lacking high end, so I managed to open them up today. Appears the tweeter was missing its magnet, it was in fact sticking to the woofer magnet.
Voice coil seems to be unharmed though. Reading about 3.7 ohms, I would have to check the other one to compare really.
I was able to assemble the tweeter again, thanks to the flange and old glue bits to center. Tested with some sine waves and it plays. Would it be very obvious if the voice coil is rubbing?
I plan on changing to new ferrofluid while I'm at it. But now the real question: which glue should I use? The 'chassis' so to say is plastic.
Thanks in advance!

Good old fashioned contact adhesive will bond metal to plastic.
