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,

Sounds like your speakers don't go very low and probably mate very well with your subs.  

I like to touch the signal as little as possible and my prejudice is that an electronic crossover might do more harm than good.

The recommendation to use an exectronic crossover in this application comes most often from a dealer selling said crossover, or someone repeating what they have heard from this dealer.  btw, the dealer is often mischaracterized as an expert.

Excuse my skepticism. YMMV.

I personally believe you should set your crossover point by ear and not by what your friend or neighbor think it should be. I use a Celodyne servo sub with my Quad 63’s and feel it works very well. I start low on the crossover frequency and raise it until you can hear the sub kick in with music playing. Then I back off about 7-10 Hz unroll it sounds right to my ears. Seems to work well for me.

If you have a point to make, I would suggest you state it. I made some very clear points and you can’t address any of them apparently. so I am assuming that you just like talking trash about peoples input.
The only point of ignorance I have is that there is a multitude of factors you failed to mention. But I would expect you to even know what they are.

As I stated If you have the money to spend play any silly games you wish, but you would have to write a complete essay to even begin to describe what you are hearing or hope to achieve. You give One single parameter that by itself is useless. I mentioned just a couple of items that you probably don't have the background to deal with and only wished to give a little caution before you make some EXPESNSIVE mistakes. But you'll are smarter than everyone here. Of course that is why you  are asking questions of the public to begin with correct?

 You see I actually studies Electronics Engineering in College and have been designing speakers since the late 70s and I have even told stories about mistakes I have made doing some of the same types of things people are asking here, just to show that messing with something isn't always the best answer.

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.
