There is frequently a roll off by 16K and one rarely sees much action at 20. Remember though, my PMC test showed a flat line to 20!
When I measure a single speaker I get factory flat info, pretty much. When I drive two speakers the two signals arrive a the single point at slightly different times due to different distances from tweeters to mic, they comb filter, badly. At high HF this is so dense it is just a roll off. Even a slight air movement will do this. I believe that is the main reason for the strong roll off Bob is seeing. If the distance is a bit larger, and the floor not carpeted , there could also be a bounce off the floor. Overall I get the impression that many Mastering rooms make a nod towards listening in the real world. i.e. not strongly damped. Mix rooms can be like that, but many of us end up in a highly damped room, so that we can tell our Rev from the room's.
I have seen tests on the ADAMs. I could show them here but I would have to kill you all.......Vertical is radically better, even though they are clearly designed to look best horizontal. The tweeter rotation restores the correct orientation when they are used vertically. This sweetens the imaging an extra bit.
That review I linked to actually echoes a lot of what happened to me. They reckoned you could spend another 6K or more on amps, crossover, and so on to get an incredible setup, mainly to be able to tailor the spectrum to taste. I believe many PMC users do exactly that. In this context the Lipinski's are incredibly good value. I hope to get to hear them sometime.

Thanks, DanDan. So for the S3A/P33A, I'm assuming (and we all know how that goes) that the midrange woofer is to be on top of the tweeter?
