Alrighty. I haven't seen another question like this in regards to driver impedence, so here goes: Is the nominal impedence of an individual speaker a design choice based on application, or do the laws of physics dictate the impedence of a specific driver according to it's design?? In other words, could a conventional driver with an 8 ohm inpedence be just as easily constructed to display a 16 ohm or 2 ohm inpedence?? Thanks to the techie folks here!!
