4 questions on soffits which I am considering adding to my plain-jane theater room to make running cables easier and to add better lighting.
1) Are there best practices on what the minimum height and depth dimensions for a soffit should be? They are not hiding anything that would dictate sizing.
2) What is the best material to make them out of? I've seen all wood, all metal (quikstix?) and hybrid. Given his stature, my default is a hybrid approach Big used in a recent build:
3) I assume the soffit shouldn't be left hollow, so what's the best thing to stuff it with?
4) If I build a simple soffit (just a rectangle, not something tiered), is there a moulding I can add that is deep enough to run a rope light within? Any links to such a moulding that I could check out at HD? Also, what rope lighting have you used?
