Hi all,
I have been using this crossover on my 605Bs for a while, favouring it over the Markwart version. My question however is : what's the correct/nicest way to pad the horn 1-2db? 2 resistors in an LPad configuration after the all-pass filter? a series resistor before or after? anything else? I have calculated several lpad values and tried them, but usually feel it brings some messiness in the crossover region.

The 18 ohm resistor placed after the 12 uF filter capacitor provides the tweeter attenuation.
On its own, the resistor would cause the tweeter level to tilt downwards as frequency increases.
This tilt is compensated for by placing the 1 uF capacitor in parallel with the 18 ohm resistor.
To increase the attenuation, I would increase the value of the 18 ohm resistor. You may also have to tweak the value of the parallel capacitor.
