Hi,

I have the following MB Quart component set:
Midbass - 6.5` "QM 160 competition"
Tweeter - 1.25` "QM 25 competition"
Crossover - "competition two way"

My crossovers were damaged and I need to replace them.
I can't find the same crossover like I have now.
I tried to find new MB Quart crossovers but the problem is that my 6.5` midbass speaker are 6ohms and not 4ohms like the new MB quart's sets (i didn't find new crossover for 6ohms midbass).

is it O.K to use a new crossovers for my sets?

thanks
Dvir

Go active or you need to replace them with the exact model due to your
unique impedance.

what part was damaged?

can you replace it with one from parts express? if its a capacitor or coil or whatever

you can use the newer xover just fine, it has no impedance the speaker does.

well... it is a long story. let's say that right now some of the items in the crossover are not original (and i do not have the original schematics).

Thanks

unique impedance.

the impedance difference will not matter to the xover at all, if anything it will be better at dampening the speakers which = an even cleaner sound and better slope.

Thanks man!
i will start checking for new models of MB Quart xovers (second hands).
maybe i'll ask mike also.

Again thanks.
