how does the FS of a speaker effect the crossover point?

I read something last night i think about not wanting a tweeter to play anything double its FS or something...im not sure

The "rules", so to speaker, are when it doubt, don't cross a tweeter below double its Fs if it's a 2nd order filter, or even higher if it's a 1st order filter, something like that. Midrange woofers should not be crossed at or below Fs; move it up higher if the slope must be shallow. For woofers the goal is to avoid the massive increase in distortion that arises when it's tasked with playing at or below Fs.

It's a good rule of thumb to avoid distortion and damaging the tweeter.

Like Trumpet said... 2x Fs for a LR2 (-12dB).

Since that's answered can we go into detail of LR2 xover or LR4. What's that mean? Why did you put (-12dB) after LR2?

LR2 is a 2nd order crossover, so the power changes at a rate of -12 dB/octave. LR4 is 4th order, and it's -24 dB/octave.

That's easy enough, I thought it would be more complicated than that with 2nd order and 4th order. Didn't know it translated to steeper slopes etc. THanks!
