I'm wanting to build an active two way without crossovers... I need to find amplifiers/dsp that allow as much EQ control as possible. If it has 64 or more bands of a parametric EQ that I can adjust, I plan to just turn down all the bands the driver won't play on each speaker. I can't find anything like this???
Ideally, I'd like to plug up my laptop, open an interface to the DSP and set it and forget it...

How much power do you need? There are some pro audio amps that can do this, otherwise you could use something like the Zoudio or Beocreate boards.

That's what I do Using the Zoudio AIO4CH. It's powerful enough for my SPL tastes and if you feed it a really good I2S input, it sounds pretty darn good to me. I have two, two-way systems using this amp.
It sounds good enough that I see no reason why it couldnt be used as a DAC, if you need more power. Surely there's a sweet-spot in the disto curves between output loading (Ohms) and power supply voltage.
You could capacitively couple, transformer couple and pad down the output signal to drive another amp that has a particular character or drive capability. It would drive 8, 6BQ5s with 4 output transformers - with all the grid drive in the world for example.
Being an all-digital amp, there's no opportunity - input - for feedback from the transformer secondaries in such an arrangement. I'd have to wonder why anyone would construct such a thing, but the same goes for a lot of other stuff I read here. Why not? It would be no stranger than some other projects that have been tried in The Quest.

I am using my PC with an Asus Xonar D2X Soundcard, Winyl as Player, Equalizer APO/ Peace GUI for DSP and 3x the "open source LM3886" ( > An open source layout for LM3886? ) per 2.5-way box. I'm pretty happy with this combination. Very much bang for a very small buck.
What do you dislike about crossovers? 😉
A collection of parametric bands set to maximum attenuation will not give the same Stop Band attenuation of a typical crossover.
