8020D treble issue - Forum

It's a bit more complicated than the material. I think I have a psychoacoustic phenomen. I always had rolled off treble in the upper frequencies with my old monitors, because the silk dome tweeters are in general (not always) have a rolling off character in the 15-20kHz region, so the energy is less and less going up to the boundaries of the human ear. But the metal tweeters have a diferrent frequency response and general they have more energy up to the 20Khz. Just have a look few speakers with metal and few with silk dome. It is almost a general thing. Yes it's dependent on the design and the room of course but this character is still there, and it's not irrelevant. Every material has sound characteristics, it's just physics. I've already measured the response and i have around +1 or 1.5 db more energy in the 18 kHz than the 5-15 kHz range, the monitors are very flat but they are still not perfect and they have their own character. From the objective point, the 0 db point the treble in the studio monitors is flat + - 2db, but in my point of view I have a bigger change in the 18-20 kHz range from around -1 or -2 db (my old monitors) to +1db (Genelec). I hope you can understand now this  "psychoacustic" case. The 2db stepping is a bit too much, to adjust something, 1db would be more useful in my case. That's the only problem with these Genelecs, I think I will change to the SAM system or to other system where I have more control, and that's all.
