Hm.... hvala sto si objasnio sta slike predstavljaju.

Isto tako da ponovim da se ne pojavljuju ovakvi lobovi na svim frekvencijama vec samo na nekim (umnosci talasnih duzina fizickih dimenzija difuzora), i to je osnova za pojavu koloracija (cinjenica da ne sve, nego neke frekvencije "probijaju")

pozdrav
