Power matching while bi-amping

I want to by-amp with a Hafler 500W for the low end and a Rotel 70W for the high. Can I just put an appropriate sized resistor in series on the Hafler side to match volume levels? I would think this would work. And wouldn't it be better to put the resistor before the Hafler, so it isn't amplifying the full signal?

If I'm way off, let me know - Thanks

What you need to be able do to is to decrease the level of the amp with the higher gain so that the level of the 'bottom' matches the level of the 'top'. You mentioned nothing about active filtering, so you'll be using the speaker's crossover which has double input terminals, yes?

The speaker is a 2-way or 3-way?
