I checked edifier international page, they don't mention using DSP on their product page for this speaker, so probably not. They do mention it on their next model - r1600tiii as well as on r1700bt. Would be nice to get one of those two measured as well. For whatever reason, r1600 tiii doesn't seem to be available in US amazon, instead next model being the one with bt that costs $150.it would be interesting to see if there is any EQ already applied in the speakers amplifier. fortunately there is a nice Output begging for the analyzer
I own r1600 tiii by the way, bought it like 4 years ago for around $120, my by ear impressions are basically: great sounding at price range and speaker size, but wish it was bit more linear, especially in the low end. I apply -2db bass on the controls and use foam pads to make it a bit more bearable. That said, they make for great multimedia speakers, and somewhat acceptable music speakers. And as opposed to lsr305, don't hiss like crazy.
