PSI Audio

Most, if not all, "audiophile" speakers have a roll-off in the highs above 10 khz, sometimes starting as low as at 5 khz. Often you also have a dip around 3 khz. That is to make it more "pleasant/musical/warm" for the listener. 

I always retune my speakers through dsp. I don’t find any speaker sounding good (to my ears) in a normal listening room without it. Mostly because of the room interaction. I’m sure the PSI A17m could be tuned to sound really good as a desk top speaker. But that might be to take away the idea with them, because the manufacturer is very proud of their tuning without using any form of dsp. I would like a lot to listen to the new A23m model.

If you're interested in pro monitors i would propose to you to have a listening to Quested.
