mmc6500 active or passive?

[black magic]

So right now my mmc6500 are receiving just under 100 watts from a c400.4. I'm getting a good deal on another c400.4. The only reason I'm considering it is because these things are craving a little more power. I want to bi-amp them so I can hopefully get a little more mid-bass (even though they sound great the way they are).

I'm wondering if its a better idea to bi-amp them using the x-overs they came with (~95 watts to each driver and tweeter) or to use the built-in active x-over in the c400.4. The only reason I'm not liking the active x-over thing is because I cant choose the frequencies i want them to play... or at least it doesn't seem that way. I'll prolly end up testing both scenarios but thought I'd get some opinions.

Sure you can.

You dont have to use the Pre-EQ.

The 400.4 has a variable crossover on it from 50-5000 Hz for each channel.

i had the same issue...seems like the crossover on that amp isn't very accurate. mine would play frequencies that i thought i had cut out entirely. i would just get an external crossover from someone else. probably would work a bit better.

ok cool. I think I'll bi-amp them using the c400.4 without using the pre-eq.

or would it be better to bi-amp it using the c300.2 for the woofer and 2 channels from the c400.4 for the tweeters?
