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

Wait I read all the posts lol. You already use a mini dsp? Just set the sub and speakers to the same point with a 24db slope and call it done.

The cleanest way is a single capacitor around 80 Hz

erik_squires. Please can anyone post a reference so I can calculate the value of this capacitor for different frequencies?

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

If you have preamp outputs and amp inputs, you can use this inexpensive device to  act as a very configurable electronic crossover: Dayton Audio DSP-408.  Get the Bluetooth dongle with it.  I hear it’s sound can be improved by using a 15V power brick instead of 12V supplied, but I haven’t tried it myself. This unit is pretty geeky, so if you are not so inclined, pass, but the same is true for miniDSP.  If you want an analog crossover with this kind of flexibility, JL Audio makes the CR-1, but it is not inexpensive!
