Hi guys, This is actually my first post here, and this may be a noob question too, so bear with me. I am interested in building speakers, but haven't yet (my dad's K-horns rock though, I know that much). In large auditoriums I've heard of a term "resonance chamber" used in order to increase the bass output in a hall. I was wondering if the same idea could be used in a room, using an open ended box of some sort. I think if this was put in a high-ceilinged room it could work. I've searched these forums and can't find anything on it, and it's hard to find some info Googling for it. Any ideas?
