Size of Soundbox and Loudness
Instruments- discuss specific features, luthiers, instrument problems & questions
Nate, look at a mariachi guitarra quintet. They have all sizes of guitar soundboards. The largest is pretty BIG.
But then, a dulcimer is not a guitar. "Uncle Eddie", the world's largest (and longest) dulcimer is not particularly loud for its size and soundbox volume. Usually taller sides equal more bass response, and maybe more loudness too. I think overall loudness is derived from several factors working together, such as wood thickness, bracing, design, string gauges and tension, etc.
