What considerations have you done with regards to how the woofer cabinet should look? It's a difficult design to get to look pleasing.

I don't think it's that difficult. As the waveguide will be the prominent feature anything unobtrusive will do. One of the ideas is not to use any woofer cabinet at all.

OB or Horn Loaded?? don't keep us in suspense!

Could be that it's only for playing solo triangle...

Thanks Marcel, I'll play around with it. Which of the demo#.cfg's that is close to the ST260 design, that would be a good starting point for tweaking?

Sorry I just started learning ATH. I'm looking at the cfg files, I only see term.s/n/q don't see k values. Can you please help point out where I could increase the value of K?

This one's for the HF108?

Is it possible to order this in an unfinished / rough surface (non-glossy)?
