So, I'd like to modfify my DPA MPS6020 for permanent bass roll-off at about 150Hz by replacing the capacitors. I can do the soldering myself, but I forgot how to calculate the correct values. (The 6020 is feeding the line-in of my D100.) I remember reading about that stuff here, but I can't find it anymore. Could someone help out?
Also, what's a good place to buy/order capacitors?
Thanks in advance guys!
