OK, time to clarify."since a 8 ohm 1.6khz crossover should equal a 800 hz crossover for 16 ohms (and it should), "
Not quite. Using 2nd order BW's for example, the 1.6kHz/8 ohm xover requires 8.8uF and a 1.12mH choke. An 800Hz/16 ohm xover requires 8.8uF cap, YES, BUT the choke needed is 4.5mH...
A google search for "crossover calculator" will turn up the web site for "Select Products" on-line applet. Sam
