If anyone could point me to a more appropriate list, I would be grateful. I have just replaced the speaker in a cordless phone with one from a pair of chain-store headphones, and I want to cut the bass response. The speaker has an impedance of about 22 ohms, and a series capacitor for a 300 Hz cutoff should have a value of about 47 ufd, but the existing one seems to be 2.2 ufd. There isn't room for a shunt inductance. Need substitution FET number SFC 2912.
