I have been asking the question on diyaudio for over 4 years now.
Most resident experts here keep answering like "you cannot", "you like bad un-hifi sound of everything sounds the same" or just "you are plain stupid/lunatic" etc.

Recently I also got a warning from moderators too. I still wonder what is it for?

anyway - what a beautiful, clear and complete schematic
BTW the picture of Your system deserves to be reposted here:

@CLS
ps.
Does it make any difference if the tweeter is placed directly on the floor or raised on a stand? Have You tested such an arrangement? Could You?

I see two reasons:
1) From our evolutionary experience (don't have a better word for it) we know, that the source of a high-frequency-only sound with a sharp rising transient must be small. Physics dictate that.
2)Look at this paper: http://decoy.iki.fi/dsound/ambisonic...%20al_1985.pdf
It discusses why our ear/brain can't place high-frequency-only sources precisely on the stereo scene. If in doubt our brain has a tendency to move them to the sides of the acoustic scene. Did it ever appear to you that you hear those triangles mostly from the center or the outer limits of your acoustic scene, but rarely from say 20?

Flooder tweeters aside, the directivity of the central channel DML panel is very wide, too. The panel is quite large (180x90cm), with a very uniform half-space radiation.

Thanks for the pictures. Now it would be interesting to hear how you would rate the "locatedness" of sounds in your room with high directivity speakers like the Danley SH-50.

Rudolf already commented on the perceptual aspects of "good" locatedness in a reflective environment.

The Advantages of Floor Coupled Up-Firing Speakers


Guys, please respect other members differing views and don't try and force issues and personal opinions by talking anyone down or poking fun at anyone.

In other words play nicely

And for anyone not sure of the rules,
