So much absortion in low frecuencies?

Hi! One month and a half in working in my studio, I have a litle problem with my monitors (ADAM p22a). It mounted on a "ultimate support" monitor stand. I've been listrening some cd and it sounds so much exagerated on high frecuencies or so attenuated on low frecuencies.

What can I do? It's posible it has so much absortion in low frecuencies and no much absortion in high frecs?

It's more likely that the ribbons are accenting the highs, and the speakers are in one or more nulls in the room - you can start here

and read through carefully, several times if necessary, then try figuring out your room enough to try a few different positions for speakers and your ears.

HTH... Steve

So what dimension I must get, from wall to wall or, form absorver to absorver? (absorvers are before the wall) remember my studio design:

Your front wall is shown as a soffit design; is this made from solid panels, or is it just absorbers in frames?

If your front wall is solid, then you can draw an imaginary line down the exact center of the room from the front panel to the rear wall (solid part, not absorber) and set up so your head is 38% of the distance from the front wall to back - find a way to put one of your speakers where your head will be (same height as your ears), then walk around the area where you want the speakers to go for actual listening - where you get the best sound is where that speaker should go. The other one should go on the OTHER side of your imaginary line, and exactly the same distances from each wall. Both speakers should be aimed at a point about 300-400mm BEHIND your head -

When you're doing the part above, don't worry about treble; unless the speaker is aimed right at you, it will be different anyway. This test is mainly to set speakers where lower frequency nulls/peaks even out.

YOu may have to shift things around a bit, but this should get you something workable... Steve

The front and the rear wall are made by 40 mm + 40 mm rockwool 40 and 70 kg/m3 cloth covered. On the left side is the window and on the righ sheetrock panels.Should I made the same measures?
