Can it be sufficiently soundproofed as to avoid torturing the rest of the household? I'm looking at building a house sometime in the next 12-18 months. The house plan is just perfect, and has a bonus room on the second floor that I'd love to use for my HT (since the house plan is so nicely balanced, I really don't wanna mess with it by building an addition later. Plus, using the existing room would be a huge money saver). Is this a good idea? Has anyone around here set up their HT room in an upper floor/loft/etc.?
