[QUOTE="Ampdog, post: 846077, member: 144"] +1 One does start with a classic calculations, but more refined loudspeaker manufacturers finalise on acoustical output performance. Problem is that no driver impedance is a simple, even nearly constant-with-f, value. In addition, some brands also try keeping the impedance reasonable over the audio band. (Comparison: 'Good' loudspeakers dipping down to 20% of the nominal impedance at some audible frequency. This, when with correct simulation both cross-over performance and impedance can be kept reasonable.) In addition matters like group delay etc. also needs to be right within the audio spectrum. Some requirements can be contradictory, thus the final result is just about always some compromise. [/QUOTE]
