I have the MGI-Imp in daily use in my TV room (bought them new in 1980) with the original documentation. What do you want to know?

in view of the very cramped space I have at home, is there anything i can do to improve the sound. i heard somewhere that you should tilt them forward instead of back. Do you a copy of the manual?

  There is no reference in the manual to tilting the speakers forward but you could certainly try it. The slight tilt back built in is meant to help some with the vertical dispersion when standing up but it doesn't really do much. Here are the manual instructions for stereo depth and imaging: "once you have located the best position for the speakers and your chair for bass performance, separate the speakers by 50% of the distance from your chair to the speakers. (For example if your chair is 10 feet from the speakers, move the speakers 5 feet apart) Now, move the speakers apart in increments of 3 or 4 inches at a time, listening carefully at each position. At some point you will start to hear two separate speakers instead of a "stage effect". If you have a hole-in-the-middle effect, your speakers are too far apart. Begin moving the speakers back in small increments until you notice a point at which you achieve a cohesive "sound stage"
  
  Next they mention Phasing: ""To fine tune the phasing between the tweeter and the midrange, place a pencil on the inside edge of the oak trim. Sight down the pencil and align it with the outside shoulder of your listening chair"
  
  Hope this helps

    I think I have found the sweet spot....took a while.... I am still trying to find a manual for these speakers. I have attached a pic of the back panel if that helps

      HiFiEngine has the IB manual. Since the differences are small between the I and IB, I'd recommend that manual. If you aren't registered, might be hard to get.

        The schematics of the crossover can be found here:

        You can get an users manual from Magnepan, probably mostly about how to place them. If you give them the serial number, they can tell you when the speakers were made. These must be very old and may have been rebuilt.
