Hi! Does anyone know any software or manuals especially on guitar speaker cabinets 1x12, 2x12, 4x12? Any info on calculating speaker placement and base frequencies of enclosures of certain shapes not only volume? I've made a few cabinets which are clones of famous solutions. Now it's time to try to calculate perfect 2x12 for V30+CL80. This combination sounded great in Bogner OS shaped and sized cabinet but I would like to have some calculations behind a new eclosure not only information based on experience.
