Connector have 4 pins..

I think they are go up to the tweeter : The green and the white..

Hi Genek, i don't know.. Normally there is no reason for any modification when the MGC-1e controller is not in use. When power is off or you have no MGC1e controller, the MGC-2 speaker act like a normal set speakers.

By the way with this the MGC-1e Amp/Controller i found :

This pictures are from the electronics at the bottom of the Speaker : Again only 2 pins are connected..

I open the second speaker.. The pictures are from behind the tweeter : There is something happen, look not safe !

I open the other speaker this evening and make more pictures.. Any idea why it is done like this ? They refoam the all speakers and it looks well done. A bit strange that they do this kind of modification. Is it possible to make a little drawing about the right connections and how to bring it in original condition ? Kind regards, thx for your time, Paul

Thx Pete, thx you all.. I found a good ( i think ) MGC_1e Amp. Found it in Germany at 20 km from my home. The guy had two of them, demonstrate it with his MGC-1 speakers. At home with my MGC-2 speakers and i hear no effect. I open one speaker and see.. : The 4 pin plug only two cables connected. All other parts looks clean. The connection with the tweeter looks very strange.. Could that be the problem ? Kind regards, Thx for your time, Paul

Hi Guys, sorry for the late answer.. I was traveling for work and did not realize all this support. Thank you all for your time and knowledge.. I try to understand all the information and come back here soon. Have a good time.. Kind reagards, Paul

Hi everybody, i am new to this forum. A year ago i buy in Belgium ( i live in Wiesbaden, Germany ) a beautiful pair AR MGC-2 speakers without the MGC-1e controller. I am searching a lot on the internet about this equipment and the missing part. Maybe someone here can help me find it ! 🙂 I also read about some alternative stuff.. the Behringher EX1 and others but i do not understand much of the technical part of it. So, i am a little bit helpless. Maybe somebody here can explain better. And yes, i had contact with Ken Kantor about it. In the pictures you see a review about the MGC-1, i still not find any review from the MGC-2.. Last picture is my little set-up : Quad 33/303, Cambridge Audio DAC, Braun 500PS and the Acoustic Research MGC-2 speakers.
