for those who may want to hold for a while on an upgrade for their diamond 9's,
here's some update on my mods for the 9.5 and the 9.cs. well, we could only do
the caps since we really don't have the values for the coils, and i don't have any
access to non-inductive resistors. here's the 9.5 modded crossover:
here's the schematic diagram for the full d9.5 crossover circuit.
highlighted items are the ones that can be modded much more easily. you can just
replace the electrolytic capacitors with the same value MKP's, or change them up
or down by a few microfarads. changing 6.8uf lower shifts the x'over frequency for
the tweeter higher, e.g. from 2.2khz to a higher freq.
you can also bypass the resistor for added HF loudness or just lower its value to
1.0-1.2 Ohms to retain some tweeter protection.
