Home Speaker Asylum

General speaker questions for audio and home theater.

So, could I use this?

80Hz at 4 ohms high pass filter. I assume I could wire this directly in line with (only) the LF binding posts and perhaps place it inside the speakers just after the binding posts.

What does the coil do?

If I wanted to reduce the high pass frequency to something like 40 or 60Hz at 4 ohms, could I simply increase the capacitor size or would I need to do something with the coil too? I could use a higher quality cap if that would make a difference since everything from the high pass frequency to the speaker's crossover at 360 Hz will pass through the filter. The specified 250 wpc limit for the filter is only half what the mfg specifies for the speakers so could I increase this with a higher quality capacitor or would the coil need to be different? The schematic is available from linked website.

Thanks for any help.
