My Emerald Physics 2.8's were designed to be used with DSP. I think it was one of the ways in compensated for the bass loss endemic to an open baffle design. Instead of using what they provided, which was okay, I got the DSpeaker X4, a fairly sophisticated stand alone DSP unit. When i used it for bass at under 250 hertz, it really did a nice job of smoothing out the bass in my problematic room. I very much appreciated its good work. But when I allowed it to be used in the higher frequencies, I was always ill at ease. It changed something for me - but I also allow that it could simply been a bias that colored my perceptions.
Anyway, with my new speakers (I went from open baffle to horns), I do not use DSP, and sold the X4. I am happy this way.
Keep the DSP in the bass, and I suspect you might be pleased with what it does.
