i have tried to add damping to the back wall but to my ears it sounds very unnatural, too dry in a way and sound field sounded skewed

i think i need to change my speaker/listing setup, firing along the length of the room instead to the width

I don't know what you did, but the OC703 has worked fine in the situations for other people we've added it to.

Much better idea. Adding controlled directivity in the speakers as well, is even better.

Adding, or subtracting, it's no good.
Sounds like room EQ, where you change the content of the disc in the name of...?

It's nothing at all like room EQ.

Hi GM and thanks for that. I have since spent several hours listening to different music comparing point source (4"TB in a TQWT) with a wtm 3way.(Peerless 830452,satori16p and sb29rdc tweet) Same everything except speakers. I have come to the conclusion that the clarity/coherence is better with the point source, although imaging pretty much identical. I can only put this down to the different reflection times caused by the 3way driver positions
Pity there aren't more coax options out there. I'd like to try one

You can angle the speakers to make focus, and WTM seems (more)optimal rather than WMT.

A coaxial + helper woofer is less optimal, since you are obliged to a setted position between T+M
