Hello... I am looking at bass guitar cabinets and I don't want something too heavy or bulky. I understand the neodynium speakers give good performance with less weight. Is there any advantage in having a heavier cabinet? How does the physics work here? My understanding is that when a speaker vibrates and moves the air to make the sound wave it will also move the cabinet. If the cabinet is moving then it may be absorbing energy that would otherwise be moving the air, therefore limiting the volume....? Maybe there is a critical weight below which a bass cabinet just will not hold the speaker solidly enough to produce more than so many dB...? Perhaps this is a red herring and choice of driver, ports in cabinets, the rigidity of the cabinet etc is more important...?
