Right crossover setting

[walter duque]

Which would be the best crossover setting for my speakers. This is what my speakers are rated to go down to.
Fronts 25hz
Center 42 hz
Sourrounds 32hz
Rears 40hz
At this time I have all speakers set to small and crossed over at 80hz. Should I go to 60hz or even 40hz. One sub goes to 22hz the other to 18hz.

80 is kind of standard but you need to test it for yourself. Maybe you'll notice a difference, maybe not. Go through the settings 5Hz or so at a time and see which sounds best in your room. Pretty much everyone will tell you that what matters most is what sounds good to you and the layout of your room will affect response.

Try it out and let us know how it goes.

The best thing is to try different settings and to measure response with something like REW.

Every room is different, so what works for us probably won't work the same for you.

Unfortunately, this is the only real way to know.

You also need to determine whether the cross over setting is for LFE only or not. If it is for LFE, crossing lower than 80hz will create a loss of information unless your reciever can componsate for that. (not many can).

But like above, you need to determine for yourself. I have mine crossed at 100hz and after a couple of months I now like it. I would suggest changing your settings a little at a time and then listening to your system for a least a week before making any judgements.

My experience.

Even though this car related its still relavent..

The hi-pass filter on my processor (PXE-H650) gives me like 10 settings for the tweeter section on my seperates.
I found 3.2khz made the seperation to wide.

2.5kz bunched the signal.

2.8kz gave the best all around cohesion of sound and staging.

As for the LFE. 120hz sounded correct but the overlap of the 80hz (mains) did'nt quite play well with the voice on singers.
80hz. Seems to give texture and balance to voice and instrument.

If that is all your equipment on that photo bucket link then you should be able to set your crossover at 60hz with good results but like mentioned try some different settings but with what you have I wouldn't go over 80hz.

It's best to have the crossover twice the F3 rating on a ported speaker.

Below that their could be issues with over excursion.

I personally prefer crossing over speakers higher than recommendations. It tends to result in better sound to my ears.

Only front mains are ported. My hearing is not the greatest anymore. For me it's kind of hard to hear any difference in my small livingroom. Any setting sounds good to me. Going by your formular it should be set to 80db, am I right?

Nice reply Isiberian

Isiberian makes a very nice reply which I agree with. What you need to realize is that there is roll-off in the lower frequency range and likewise upper frequency range on any specific speaker, It is not a sharp square wave cut-off as many people assume but a 6dB or 12 dB roll-off. Therefore take with a grain of salt the frequency ranges published for specific speakers and don't crossover close to the limits. You will be much more pleased with the overall sound produced as Isiberian has stated.

What kind of speakers do you have. If you have an 8" driver you can get lower.

But 80hz(not db) is probably a safe easy setting.

It may be a bit high for some subs though.

It did mean 80hz. All speakers are made by Source Technologies. Front mains are 400 watt powertowers with (3) 8" drivers.

I'd actually try a 50hz crossover on those speakers. It would allow you to run your sub hotter and more corner loaded.

Most 8" drivers do fine at 50hz for a crossover. This would also make music listening better IMO.

I set it to 50hz this morning, it did sound good. Listend to it only on low volume. I think that's the right setting. Thanks. Seemless intergration.

It is good advice, but depends upon the slope of the crossover. With 24db/oct. filters, one can be relatively close to the F3 and not experience any issues.
