The 25uF sounds like the way to fill in the 1-5khz range with the tweeter

The fuse bypass - to clarify - what you did was desolder the brown wire from the one terminal at the end of the fuse holder and soldered it to the other end where the resistors connect? If so then you probably did it right post a photo and we can tell better..

Yes the ribbon is much more sensitive, and with the fuse bypass it's almost overbearing albeit cleaner. I may try a 3-4ohm resistor to further pad the ribbon down, or should I just try 1-2ohm resistors at the attenuator posts? If I tweak this value it shouldn't affect the bass impendance, right?

And yes I moved the brown wire to the top of the resistors.

  To clarify the above post I meant trying a 3-4ohm resistor at the crossover underneath the plate. Would this affect bass panel impedance (and effectively crossover point) or would only the ribbon be affected.

    It will change the impedance of the integrated speaker speaker. Get a few resistors at intermediate values so you can fine tune the tweeter level to your liking. Say 1/4-1/2 ohm intervals.
