Crossover settings (receiver) vs frequency range for speaker.

post #1 of 5
Thread Starter 
I have a vsx 1021 pioneer fs21's bs21's c21 and a Bic F12 sub. The sub is set to 90 on crossover, and receiver was set at 80. Recently I tried the receiver at 50hz for crossover. Surround during LFE sounds so much better, but can this harm speakers? The fronts start at 45hz for rating but the BS and C speakers are rated starting at 55hz. Sounds really good set at 50hz and can only step up to 80 for all though. What do you think?

No, it won't hurt the speakers. If you prefer the sound from a 50hz crossover, then use a 50 hz crossover. You may want to set the crossover on the sub unit wide open (highest setting) and let the receiver handle things completely.

There are two factors to consider with respect to the crossover frequency. One is being able to directionally locate the sub, which you don't want. The lower the crossover the less likely you'll be able to directionally locate it. The other is the capacity of mains to handle low frequencies without audible distortion. The higher the crossover the less distortion there will be. Where it will work best varies with every set up, every room, and every pair of ears, so the only thing you can do is try various frequencies and go with what sounds the best to you.

Thanks this is good to know. 50hz it is...I enjoy it much more here, the bridge scene in Cloverfield esp sounds better with all speakers supporting a little base it gives a great 3d positional effect of the snapping cables. So out of curiosity how do you know when it's too low, when you could harm the speaker? Or is that more just a matter of power?

You'll hear them complain if you try to run them too low and/or too loud.
