I've got a pair of Dali Ikon 6 and will be getting a Minidsp 2x4hd- one pair input, two pair output (mid and bass). The Dali have 2 mid drivers and 2 tweeters, and are able to be bi-amped.
Can I sent one output of the minidsp to the tweeters and the other output to the mids? Good idea or bad? I'm new to DSP
edit: sorry if this is the wrong sub-forum. I didn't want to clog up the others with a non-diy question

Bi-amp
Theory is: Preamp -> Minidsp -> amp1 (tweeters) and amp2 (mids). Both power amps are the same model

those speakers have internal crossovers.
you do know removing the jumpers on the speakers binding posts won't disable or bypass the internal passive crossovers right ?
so biamping with an external electronic crossover or dsp is pointless.

I'm not hoping to bypass the internal xover. I'm curious as to whether DSP would be "intelligently" tweak the power going to each terminal pair to affect the speaker's balance.
Eg, a measurement may indicate that I need less treble, so DSP decreases power on the amp that sends signal to the treble terminals of the speaker's xover

To do what you propose you can simply use one amplifier and one set of outputs on the MiniDSP. Use the MiniDSP to equalize the system using REW measurements. (Get a UMIK-1 with the 2x4hd) Use REW to do the measurements and generate the filters and upload to the 2x4hd. MiniDSP has a detailed guide for how to do all of this on their site.
I have an SHD which uses Dirac3, but that's essentially what I am doing through active crossovers and six channels of power amplification to a pair of 3 way speaker systems - driving each driver individually.

I already have 2 identical power amps so that's no hurdle. I'll experiment with bi-amping with DSP (without removing the passive xover) to see if the extra flexibility provides better results. I'd love to get rid of my subwoofers, so hopefully this will somehow work better than single-amping
I already own a behringer ecm8000, which has a REW calibration file.

If I were you at this point in your thought proces I would do one or both of the following:
1. Forensically measure your speakers, individual drivers and network. Bypass the internal crossover and have a whole lot of fun redesigning them. You may not better them but you will get a lot out of it in terms of learning about crossover design and perhaps gain insight into the design.
2. Bi-amp your speakers but send them the same signal from your DSP and tickle them in to a house curve or EQ that you like (as Kevin has suggested).
WHat you are proposing to do is untraditionally half way between these two and may pose more problems than solutions. Either way you'll have fun but I think the two offered options give you the best chance of better sound.

For clarity, I have no fantasy of the DSP controlling how the requency is divided between the drivers. That job is handled by the passive Xover, which won't be removed. My hope is to use DSP+REW to do room correction, but give the DSP more flexibility by allowing it more "direct" access to the individual drivers.
I figure that if the DSP has 2 independent outputs and my speakers have 2 semi-independent inputs then perhaps there'd be a benefit of separating them out rather than using one DSP output and bridging the speakers' inputs.
Honestly it sounds easier to just try it and compare the results to using it bridged
