Yes, I know... It's terrible. It's for a buddy of mine to use temporarily until we can get him setup with an active xover.

Thanks guys.

I'll give it a shot with -18db=

R1= 50
R2= 12

I say all this as a reminder that the three components are part of the filter formed also by the compression horn and the Butterworth crossover filter. The thing is designed to provide specific damping at the crossover frequency, so that the first couple of octaves are flat before augmentation starts. This is all outlined in detail in the π crossover document.

If you wanted just a flat attenuator with no compensation for the compression horn, you would choose R1 and R2 values that added to be approximately 8 ohms, but that acted as a voltage divider, cutting power to just under 2%.

Long story, it's for a temporary network for a car horn. Doesn't need the attenuation because of the flare rate and whatnot.

Thanks dude.
