Hi,
I am a big fan of the ST-10. They throw an incredible soundstage as well as have a uncanny ability to control the woofer producing super tight bass.
Currently I have a pair of ST-10 wired with active crossover and biamped.
I wonder what is the best way to connect the amps. Should I have one ST-10 driving the woofers and one ST-10 driving the mid/tweeter, or should I have one drive each L/R channel woofer/midtweet.
The woofers draw a lot of current and I wonder if there will be enough crosstalk that would affect the distortion on the other channel in the same chassis.
cheers.

Your best bet is to have each st-10 connected to both speakers. To really do biamping you need to disconnect the passive xover internally otherwise you are not getting all the benefits. If you speakers are three-way, you can leave the mid and tweeter connected to the passive xover. When done right your speakers will sound like five times their price. Good luck.

I am running active crossover. the output of the ST-10 goes straight into the driver without any crossover components.

Are the speakers DYI?

yes

I'm a little late to the discussion, but here's my take:
There is the very real condition of channel crosstalk!
So, if you use one St-10 for both woofers of the two channels, the crasstalk would result in "less than perfect" stereo, but nothing harmful.
If you use one St-10 L channel for the woofer and the R channel for the tweeter of, say, the left channel, the crosstalk between channels will "pollute" the base frequencies with the higher pitched ones, and viceversa. If you no longer have a passive after that point, this could cause, at best, distortion on your speakers, and at worst a lot of damage.
So, with two amps, do biamping. For independent left and right amplification, you will require 4 monoblocks, I'm afraid.
That's my educated guess, anyone is free to prove me wrong and I am happy to learn!
Best regards,
Rafa.
