[QUOTE="Ctesibius, post: 6294208, member: 564131"] Max power is utterly meaningless. When (respectable) companies site "rated power" they are referring to "RMS power" and not max power. If you connected a 4ohm resistive load to the amplifier and caused the amplifier to output 100w, then the SNR would ideally be Xdb and THD+N would be Y% (assuming the amplifier was accurately rated). Well, it is the [I]real[/I] measured THD+N vs Power for a JL 300/4.....so I would say it's about as empirically real data as you're going to find [IMG]//content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif[/IMG] The general shape of the graph will be fairly consistent across most solid state amplifiers. Power levels and THD+N values will of course vary from amp to amp. The reason I said it was for example purposes was more to indicate that we didn't need to consider [I]what[/I] amplifier was measured for that graph. I was using the graph to demonstrate my point. If that makes any sense ? No, I meant the component set's passive crossover. Whether or not you can bi-amp the speakers through the passive crossover is going to depend on whether or not the passive crossover accepts separate inputs for the woofer and tweeter. I don't follow your question. If you're asking if, for example, the front two channels can be made to output less power than the rear two channels....then the answer is yes. [/QUOTE]
