Does it look as if the side mid and the added resistors have been rewired to be in series or parallel with the front-firing mid? I'm wondering if perhaps someone who didn't have the MGC amp rewired the speaker so the side-firing mid would produce output from a regular stereo amp.
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 !

The green (-) and white (+) wires go directly to the 6-inch ambience driver.
The resistors soldered to that loose circuit board appear to be a modification.
Pins 3 & 4 from the rear connector must be attached to the main board, which doesn't seem to be the case with your speaker.
Pin 3 to one leg of the .31 mH coil, and pin 4 to the 12 mF capacitor.
It's hard to tell from your photo if the green & white ambience wires are soldered to the proper location on the main circuit board.
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 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.
The picture above is a reproduction from a album cover 'Miles Davis hand' by Irving Penn
Kind regards and thank you for your time,
Paul Croes
