OK Ian,
If I can now go a bit further - So I am beginning to get an understanding of the effect (in my thick skull) but if the effect is not related to different driver components, then it is (my assumption) that it IS related to driver placement/arrangement. If it is not then I don't fully grasp your comments about your "discovery"(my word-not yours) of the higher quality sound from the configuration for the VP150 center channel speaker (i.e. WTW in the VP100 vs the TWWWT in the VP150)[or for those that prefer, use M instead of W]
It was references to some other message board posts and their comments about lobing in the VP150's driver arrangement that started all this. Now I am just trying to understand the science (or is it mystery) around the lobing effect.
Appreciate any other info you could deposit here. Thanks!!
Randyman
