perhaps im mistaken then. I thought Elias' speaker was just L and R. Either way I havent listened to or built his speaker. Just my impression looking in from outside, without having tried it

you can always try the left speaker, summed left + right speaker, and right speaker.

Just use 3 drivers and play with levels, play with a squeek of delay.

Yes race won't be there, but it gives a solid center and a panned left/right, versus a diffuse center.

Look at the size of this bugger!
I have a new name for it. The "Ambiolith"
We have a monolith....we have a stereolith, we now have the...
AMBIOLITH...LITH...LITH...LITH
haha!

Looks like you've done an overly wide and tall stereolith without the tweeter

You should have put a third line in the center and used the matrix

its impressive, but why did you make it black? why not white...it could have been less visible

Yeah. I wanted to test the flooder theory first, to see if I would get good separation. I did, but only in the FR of about 3kHz and up, and to tell you the truth my heart was in an omni design in the first place because I knew there would be a mismatch between RACE and the reflected signal.
I will try the matrix theory with larger full ranger point source drivers. Maybe I will just clone yours and see how it sounds.

Ever since I saw 2001 space odyssey, I wanted a monolith as a design statement! I'm not kidding about this

Wrong, because perceptually the mid freqs are coming from the side if you'll use the matrix x=0.5.

This is one of the scenarios where traditional precedence effect breaks down.

See this simulation. Here the stereo signal is fully panned to the left side. Note the direct sound is much weaker than the sound reflected from the left wall. Reflection overrules the leaked direct sound, and stereo is enabled.

Yes exactly there is no way to steer the midrange freqs by only using 2 drivers. You'll need 3 drivers and the matrix. Then only a vector is formulated which can be steered by the stereo panning.
