Hi, I just wondered about something: if you use an amp with multiple cabinets, are these cabinets always matched in volume? Ofcourse if you use 2 identical cabinets they will output the same volume. But how does this work with cabinets with different layouts (eg. 4x10 with an 1x15 or a 2x10 or smth.)? Or different drivers/efficiencies? Are drivers "configured" by design to match other drivers, or is this just a magical byproduct of the electrical wiring? Is the effective "force" output by the amp nicely balanced over each speaker/cabinet so they are matched volume wise because of the electrical properties of the cabinets/drivers/... ? Or is this greatly because of design qualities and is there some kind of de-facto design standard among cabinet/driver manufacturers that a certain load should lead to a certain volume? Or is this just a logical consequence of the laws of physics? However there is such a thing as driver-efficiency right? Or does this not matter in such a big degree that it is audible/a problem? In the extreme case of a 1x15 with a tweeter, the cabinet manufacturer will decide through the cabinet design how much volume is produced by the tweeter in relation to the main speaker right? I believe this is even configurable for some cabinets? But when combining different cabinets I could imagine one would also want to balance these cabinets with eachother. However this does not seem to be possible / necessary? I am curious to the logic/physics behind this. I'm SURE some TB veteran will be able to provide a good explanation for this. I hope it might also interest other members. Somebody who can shed a light on this?
