Stepped Attenuator for HF gain setting on crossover

I have a two way crossover and the horn driver gets ahead of the two 12" woofers real quick. I can use a Mini DSP HD I suppose and tame this thing but what I really want is a good way to attenuate the HF horn drivers to match the woofer output on a crossover. Right now I am using a pair of L-Pads from Parts Express but I want something more precise than those.


I read about stepped attenuators and Goldpoint comes up often so I get a set in. These things are tiny and I can't find any wattage capacities on Goldpoints units nor has Goldpoint answered the phone so far. Honestly I have not tried all that much to reach them so not casting shade here. I figured I would ask here while waiting to hear from them and see if these are even what I should be using.


I am told that you can measure output from an L-Pad to derive resistor values for a two resistor L-Pad.


So anyone have any input on the Goldpoint and attenuating 150 watt driver down to match two woofers? I am afraid I bought something way to insufficient for the wattage I will need to take care of.



Any ideas other than trial and error and a suitcase full of resistors to figure out values? I was hoping to use the Goldpoint as both attenuators for my system and a source of accurate measurement for resistance values I could measure off them then make fixed L-Pads for further ones.
