I'm interested in upgrading my Monitor 7C crossovers.
Has anyone completed a 7C x-over upgrade? With good results???
Does anyone have a Monitor 7C schematic that can post a list
of crossover capacitors and resistors needed for this upgrade?

Thanks,
Dennis

    look under troublshooting,,,you will find the schems for your model.I just finished my 7c's used solens and mills,, they sound very good,a little more bottom,,more seamless IMO,,and if you posess soldering skills, it's pretty easy, I also replaced the binding posts,,have fun.:)

    George,
    Thanks for pointing me in the right direction.
    Did you replace the wiring to driver & tweeter
    with heavier guage wire? Is this worth the effort?

    nope,, just the caps,resistors,and the binding post. As I mentioned in another post, I would have used sonicaps instead of solen,except for the fact that I'm doing four pairs of speaker upgrades,, three for my daughters (3) Christmas presents, and one for myself(mine have sonicaps) Have fun with those 7's
