Affects of mixed driver impedance

[retroman]

Hi all,


In terms of designing a crossover, is there any problem putting drivers together that have different impedances? For example can I easily mix a 6 ohm woofer, 8 ohm midrange, and 4 ohm tweeter? I've never tried and don't plan on doing it but have been curious and just never bothered asking.

Your advice and opinions are appreciated.

Many speakers are built with non-matching driver impedences, but impedence compensation should be designed into the crossover to negate it.

Not doing so can result in significant differences in relative driver output, which will of course have negative effects on the sound quality, with one driver dominating the other.
