My 4Pis are about 5 years old. I just ordered the H290C horns and already have the DE250. I was just checking my crossover and removed C1 to try it out.
I do not have Rs shunt resister installed and was wondering what wattage it should be?
I also noticed C4 in the woofer circuit was 20uf instead of 10uf. Was this an early version and should it be changed?
