In Reply to: My horn pics and SET 45 amp question ? posted by Les Hudson on March 2, 2007 at 13:29:59:
159000/(50cps*impedance) for a 6BD per octave filter. So if the input impedance of the 45 amp is 100K, you need a .0318uf cap in series to block the lows.Or, if you don't want to add a cap to the system and your amp does not use feedback, you could use the same math to change the value of the coupling cap between the drive and the 45 (based on the resistance value of the 45 grid resistor).
