How do you high pass your main speakers?

Also Tony, Before you go complaining to management as some have in the past, I would suggest you actually READ what I have and HAVN'T said. Notice that I never cut down anyone else advise. Other that to caution you and to give you some SOUND advise on reviewing YOUR motives, I didn't cut you down Your equipment, or your choices. I suggested that MAYBE your speakers might be deficient or inferior, but you opened with that! I just gave one of dozens of reason that there are NO SIMPLE SOLUTIONS to what you are attempting to do.

I personally believe you should set your crossover point by ear.

That practice has worked well for me.  Knowing the frequency response curve of my speakers does help as a starting point.  When I finish setting up my two subs, I subtly miss them when they are turned off.  A remote control to adjust the sub’s volume +/- 1,2,3 helps optimize for different listening levels and musical material.

Why am I not surprised.

You are correct. The ATC don't go much below 55Hz, but I knew that before I bought them.

I agree 100% with your assessment. I just thought I would ask the question so I could see if there was something I was missing. I also used the speakers as the front speakers in a HT application via HT bypass so limiting there response is not ideal. 

All things considered I am very happy with the sound quality as the system is currently configured, so I am guessing I may just play around with a slightly lower crossover frequency for now.
