I found it very interesting that this Ilkka fellow ABSOLUTELY refused to listen to the EP subjectively in it's correct orientation. He stated "But I was using the EP-600 in the downfiring configuration (placed a few books on each end) and it obviously didn't like it. There was a good 2.5" between the woofer and the floor, but when looking at the results, airflow was propably restricted" because "I had to use this configuration, because others were giving me a very bad FR." Note also that he tested an upright 600 in a horizontal orientation. I don't know if his claims that this makes no difference is true. I have seen posts from Ian in this forum stating that you shouldn't do this. I do know that Scott Mitchell put up great numbers as QB for the Detroit Lions a few years back but was eventually released because in reality he made bad decisions and lost games. Numbers are never the whole story.
