What is a good low-end crossover frequency setting for 5.25" midrange home speakers?

Question

I have six 5.25" midrange speakers, two 2" tweeters, three 1" tweeters, and two 10" woofers in my home theater setup through which I play music and movies. Currently I have my crossover setting so that frequencies below 100Hz do not hit my 5.25 speakers. But it sometimes sounds a little better at 150Hz... maybe because they are cheapies. (I believe the tweeters have built-in capacitors which limit their frequencies to the high-end.) Please advise what is an average frequency range to limit low-end frequencies for 5.25" speakers. Thanks!

Answer 1

You had let your ears be the judge here and that was probably the best thing. Most systems that I have seen can be set anywhere from 70Hz to 150Hz. I set mine at 80 Hz, and that worked fine for me. But, one thing that you need to know is that NO speakers and rooms are alike. So, there are no real solid answers for this.

Answer 2

It really depends upon what the 5½" drivers' frequency response rating is.  It sounds like the higher up you x-over the better.  Try 200 Hz or 250 Hz and see which sounds best.  That will be your best way to find out -your ear.

Answer 3

If you are setting your crossover that high your speakers are not very efficient.  Secondly, a crossover that high will allow you to localize your LFE which you shouldn't do.  The semi-standard is to set it at 80Hz.
