Can I Use a Focal 4 Ohm Crossover with a 2 Ohm Orion Midbass

Post by Tone »

Will this burn out my crossover - does anyone have any suggestions or knowledge about doing something like this?

Thanks

The crossover point will be off

Try this link to see what happens to crossover points at different ohm loads:

This one is better if you want to build your own:

Just goggle speaker crossover design you will get a couple dozen great hits from that :)

So as long as I compensate the crossover point with the ZPX2 it should be okay even if I ran as low as 1 ohm... right?

Check you crossover components and see what frequency they rate at, at different loads, after a while they become worthless for doing anything you wanted in circuit and thus useless. I don't think you want useless components in the way of your music.
So dropping speaker loads on 4 ohm crossovers becomes self defeating as you get closer to 1 ohm. The components are still there just not doing anything you want them to do, so the reason for having them in circuit sorta goes out the window. I hope you follow what I am saying :)


Oh the crossover components will survive but you speaker voice coils may not, mostly due to the speakers being operated out of there proper ranges. :wink:

The frequency cutoff will be HIGHER. it will probably sound like poo. I tried doing this. It sounded bad cause the load was way off.

if you only hook just the +'s up it will work at 6db per octave

Um I think you have to rephrase that. Cause you need both neg and pos to have a speaker work!
