Speaker Crossover: Interchangeable?

[Bob Brooks]

I have two sets of MB Quart 4" component speakers. The shallower model (QWC-100) goes in the dash, but they came with surprisingly large crossovers. I am putting MB Quart PVI-210's in the rear panels. I would like to use the large QWC crossovers for the rear speakers, and use the smaller crossovers that came with the PVI's for the dash speakers.

Seems to me they should be interchangeable. It's all about sending different sound frequencies to a woofer and a tweeter. This is not an audiophile installation, FWIW.

Man, is it hard to get enough advance information about these things to know that it will all fit! At least I conquered the mountin of these speakers to the factory grilles; no minor accomplishment.

While they may "work" you will suffer a loss of fidelity. The crossover is designed based on the inductance and capacitance of specific speakers. Changing the size and design of the speakers changes these characteristics considerably.

On Sunday I contacted a friend of mine...SERIOUS audiophile with in-depth knowledge of electronics, amateur radio operator since 1958, etc. He saw no problem, so I swapped them. Sounds MUCH better than the stock speakers. Will be interesting to see what the MB Quart techs say.

Thanks.
