How many dB down so you don't hear breakups

[ct991]

I'm working on my crossover for a 3-way center channel but I don't know if the slope for the midrange is steep enough so I don't hear the high-frequency junk from the metal cone mid. As of now the breakup stuff is attentuated to -33dB below reference. Realistically, would I still hear any degradation in the sound?

-33dB should be far enough out of range that it won't jump out at you.

I don't even remember how far, just where I want it in my default window in Speaker Workshop.

edit: so I went and looked, seems I shoot for close to -50dB. That doesn't mean you need to, as -33 should still be far enough out to not cause issues. Maybe. This is where a digital crossover can be fun, testing this specific type of thing and your own ears. They still don't sound so good for high frequency use, however (IMHO of course).

Atleast 50 dB is my experience with metal cones.

I'm with Taco on this one.

Thanks for the info guys.

My next question would be...can you mix the orders of the high-pass and low-pass sections of a bandpass network? (ie. can I have a 2nd order high-pass section and a 3rd order low-pass section on my bandpass circuit?)
