The .15mH coil will cross at 4000Hz with a 4ohm speaker load. Your drawing shows the woofers wired in series which would be a 16ohm speaker load. You need to wire the woofers in parallel to get the 4ohm load.

Ah. dont know why I calculated them as if they were 4 ohm. I also have 2 coils to crossover at 4kHz with an 8ohm load. Can I place one before each woofer and they will function fine?
thanks

Here's the wiring so you can use the two coils you have. Remember that the two parallel woofers present a ~4ohm load to the amp.

Make sure you separate the 2 inductors and/or mount them at right angles to each other.

Have Fun,
