The 18's are superb🙂, but so are the 9's. I compared the BL18 with the BL20 and put it down on Beoworld. I have chosen the BL18, because for me the 18's are at least as good if not so better for music. For video alone I would have been struggling because the BL20 is a beast for movies. I think the BL20 are better speakers as the BL9, the differnce is mainly in the low's. But at this moment You can get a good deal on the BL9. You have to listen for yourself because it is all a matter of personal choise.
