I would like to make my own high pass filter with a 60 hz pass. What would one need to do so . thanks in advance.

Brown,

The answer to your question is dependant on where, and for what, you are implementing it.
If you are doing it on a line level signal (such as feeding only the signal above your subwoofer cutoff) it could be as simple as changing the input capacitor on the amp driving your mains, if a 6db highpass works for your situation.

So you need to tell us the context -
line or speaker level
impedance of the amps if line, or speaker if speaker level
how much overlap and attenuation you need
etc....

If you need a 24db/oct highpass, that another situation which would need active circuitry.

So if you could be substantially more expansive in describing exactly what you're trying to accomplish, it would help greatly.

FWIW,
Paul

Well Said Paul 

Good luck with that cable gig ..in the not so distant future I plan on purchasing one of your power cords. looking forward to it

Is what I'm using at 70hz. You have choice of slope and frequency.

Mike Dzurko at ACI offers an inexpensive, well working 65Hz in-line filter. "Why build your own when you can buy a pro's cheaply", is my motto. Best $35(?) I ever spent (in audio). (Although I ended up using 85Hz in the end.)

[Brown]

Paul thank you for the clarification. I'm a dumbarse. It would be for the line feeding the main speakers.  Rockadanny that ACI in line appears to be what I'm looking for. Tried the Harrison labs ones but the top end was affected in a negative way  [ hard &bright ]. For $35 I'll try the ACI's for now.
 Thanks again for the quick responses.

[Brown]

Konut, the Marchand passive is looking good. I'll buy both the Marchand and ACI. Once broken in a review will follow. thanks.

[konut]

Looking forward to your findings.

Brown - Oooo! ... Please do review. Thanks!

Well the ACIs are in the house. Worth every bit of the money spent. No intrusion on the sonics. The amp now breathes a little easier. No strain better mid bass and to my suprise the top opened up some more. Overall more dynamic and just smoother at the same time. Thank you for the lead . Bless you.
   The Marchand will have to wait until a later day. For now this is for me the best money ever spent in 30 years in this game. REALLY.

You can do this actively with an opamp or tube as well.

Since you have found your answer though no need to look farther.

A simple RC network can be built into your main amp or on one pair of your preamp outputs.
Here's a calculator to determine the resistor/capacitor value for each channel:
