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,

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

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!

 

I don’t know if this will get me canceled, but power my SCM 19’s + Dynaudio sub (18s) with Arcam AVR + Arcam power amp and use Dirac for room EQ and Crossover.

I am very happy with the result.

I don't mind people experimenting, BUT don't do something that can't be reversed easily. You seem to be saying that yo don't like your speakers or that yo know better than the engineers that designed them. I must ask what started this line of thinking for you? Was it something that you were told or read. I would dump that like a hot rock. I guess if you have the money to spend it is ultimately your choice, but just to accommodate some frivolous fantasy seems to be wasteful. OR maybe you really do have CR@PPY speakers. so what the heck, experiment away!
As far as what crossover point and the degree of rolloff, ISN'T that totally your choice. No one reding your post has any idea what yo are hearing so how can anyone hear make such a decision. This isn't something engraved in stone. That is why we spend our money on quality equipment so that we have the advantage of highly educated and experienced engineers to make these decisions for us an we don't have to play games with our equipment.
As I mentioned in another post about crossovers and capacitors, just take Mundorf capacitors, there are probably a dozen different versions of any given capacitance made my Mundorf and they all have different characteristics so do you have the engineering background to choose which one you want to use to achieve some arbitrary results that you woke up this morning and didn't like something you thought you heard?
