[QUOTE="The_Quiet_One, post: 8491342, member: 614562"] Nominal Impedance directly affects how the load reacts to power input considering a subwoofer and amp are a highly complicated, coupled electromagnetic circuit. It's only one of several variables that play a role, but it is there. Inductors by themselves get mathematically hairy real quick even without throwing in a non-constant BL curve, heat dissipation/buildup, the amps internals, etc....You can't just say P=I*V*cos(phi) or I=V/Z and expect that to be able to describe the situation fully, especially considering you're basically ignoring the time dependence of each EM entity. This is a dynamic situation where I believe your experience/knowledge in approximately steady state/well defined systems leads you to oversimplify what's going on. [B]The best answer IMO is it depends on way too many variables for anyone to be able to say definitively what's best for any person's setup.[/B] I do agree; there are tons of other areas that need to be optimized first before anyone get their pa[B]n[/B]ties in a wad about brazilian vs korean. To be honest I thought the biggest issue about brazilian vs korean was the fact many people claim bad QC/reliability or inconsistent throughput across their frequency response which has more to do with topology. As far as power at higher voltages I don't think I've ever heard anyone complain about non brazilian offerings at higher impedances.:yumyum:JBL Crown [/QUOTE]
