Hi Tenson,
Are you saying that we should pick whichever measurements suit our particular sensibilities or tastes? In other words the (perhaps relevant, perhaps not) measurements of the items we like the sound of, those are the ones we should use.
We might as well just listen to the stuff!
Of course the measurements you consider important are likely to be different to the ones I or anyone else does. Using measurements as any sort of yardstick is only helpful if everyone agrees on what they should be. We all have an idea what a centimeter or a Kg is so they are useful units of measurement. I'd disagree that such useful measurements of 'quality' exist in electronics or loudspeakers yet. Certainly we can measure impedance or sensitivity but they aren't really useful quality marks. I'd agree with some of your requirements re speakers but I imagine several other speaker designers might disagree with them or have other priorities. If it was as straightforward as using the criteria you mention the world would be flooded with marvellous loudspeakers by now but it isn't and we aren't.
