RE: Those not well done measurements !

Thanks for your input. I guess it's worse than I thought, with consumer magazines.
But let's not forget why they're there: make the (dominant) idea look as good as they can. If a cone-speaker was decided by insiders to be The Big Thing -then most promoting, show reports, class-A rated products, will be this type. Skip the waveguide and horn (2 distinct types). But if you review one, don't measure it right.
That said, a tester can't cover-up everything. Look at the phase and electrical impedance of many cones -TERRIBLE. Then deviations from linearity, if you can find a chart, will show serious deviations at 95db, as volume increases.
It's revelations like these that guided me to the horn. Along with their performance, of course.
