How do you high pass your main speakers?

I have been very happy with the distributed bass array I added to my system, but from what I hear, the optimum method of integration is to high pass the main speakers.

Two questions:

1. What are my options for accomplishing this? Does this need to be a feature built into my amplifier or is there another component that needs to be inserted in the chain. 

2. What crossover point would be ideal? What frequency and amount of rolloff would be best if my speakers are ATC SCM19's which have a frequency response of (-6dB) 54Hz-22kHz.

Cheers,

Tony

You can insert some Harrison Laboratory fMod hi pass filters into the line (RCA) from your pre amp to the amp(s) driving your main speakers. 

They have hi-pass cutoffs at a range of frequencies and aren't too expensive so you can get some at 30, 50, 70, 100hz.... I got the 50 and 70's when I put some subs on my system. 70 seemed to work best for me. They filter at 12db per octave so you still get some music below the cutoff level. 

That'll take stress off your main amp(s) and leave those frequencies and below to your bass array.

Does your integrated have a pre-out /amp in feature?

Does your integrated amp have a pre amp out / amp in feature? If so just run the Harrison filters with rca jumpers.  I'd suggest the 70hz ones for you. 

That said, I kind of agree with the folks who say to just carefully  dial in your bass array.  

The beauty of your setup its you could try both to see what you prefer. 

Good Luck!
