Lack of depth problem

A thought, beyond the set up issues and choice of electronics both of which play a great role in creating a good sense of front to rear depth of image and which we cannot comment on because of a lack of specific information. (BTW what are you using for electronics and how far are your speakers apart and how far from side walls, what have you done to reduce/eliminate first point reflections which are killers for good depth of image.

Are the sources you are listening to recorded properly so that the depth of image is present in the recording. Most are not so it is not unusual for absolute depth of image to be missing. Like trying to get blood out of a stone.

Vett93, FWIW, in my set up the location of the listening chair is every bit as critical as the location of the speakers. I note you are moving your speakers about but you haven't mentioned moving your chair. Don't miss the opportunity to try this if you can do so. You might also get a little reduction in the 100hz hump as well. Might.

Vet, Looks like you have pretty decent stuff, a decent sized room and dimensions, as well as appropriate damping, for a good sense of depth of image. BUT, in considering advise (and giving it) we should be mindful of how YOU define depth of image.

Some feel great imaging has a sense of airness, like looking at the stars at night. Very clearly defined bright spots of light against a dark background BUT I would see that as closer to 2 dimensional.

What I call 'depth of image' is more holographic, a sense of being at the event, a sense that you could walk in amoungst the players. Front to back depth of image, with the front plane being just slightly behind the speakers and the depth extending backwards from there and the performers/instruments have a sense of body. Hard to imagine sometimes until you have actually heard it (and you do need that on the recording!).

Assuming that you would like to have the second type of imaging that I described, I would suggest that you simply move your listening chair forward until your ears are between 9 and 10 feet from the speakers (inches make a difference, BTW). I would also suggest you fiddle with toe in as you fiddle with listening distance. Its the combo you're looking for. Different speakers have different radiation patterns so its hard to predict, but a couple of my favorite toe in set ups, depending on speakers, sidewalls, and ceilings, are with the axis of the speaker crossing just in front of the listener position or with the axis crossing just behind the speaker head. Doing this creates a, sort of, near field experience with pin point imaging, and while it may not get you to absolute holography due to other considerations, it would probably help a lot with a sense of front to back depth.

Hope that helps a bit.
