I have another question: I've placed both speakers close to a wall, far from corners, with a low Zout Class D amp, and Silbury still sound full and without any need of subs, while in comparison FHXL would benefit from a sub on certain genres. Is it normal and would it be balanced with an higher Zout amp? I've not tested them both with a feedback-less tube amp.
I started with light walnut stain with a small amount of black, sanding, light walnut stain with a small amount of rusted red, sanding, light walnut stain. It is very similar.Can anyone suggesting me how to proceed?
