This is my experience with the 6x9 set as well. To me, they sound pretty clear but are really lacking in the low-mid range. I thought maybe I wasn't giving them enough power (45w/ch), but the more I'm reading it's starting to seem like maybe that's just how Focal's Integration line is.I can't speak for the Focal 6x9 set, but I have fooled around with the Focal 6.5 Integration set and am not impressed the least with it. 2mm xmax and hardly any bottom end, I'm not sure what others see in them other than it's "Focal". There's even a Russian review of the 6.5 set stating the obvious except that distortion in the midrange is lower than comparable sets, but that should be a given since it isn't doing much below. Does that spill over to the 6x9 integration set? Can't say, but I don't see the value in that series.
