I am trying to add the 30923 attenuation circuit into my cloned N-800-F crossover. The area circled in red is replaced by a 16ohm L-pad. I am need to figure out where to splice the 30923 circuit into the crossover. Any assistance would be appreciated! I also would probably use the L-pad mentioned in the text. Additionally, how accurate must the resistor values be? It is hard to source high watt 7.8ohm and 13ohm resistors. Thanks in advance! I moved this query from the general speaker forum to here. I hope the Moderators are OK with that.
