OK, let me try and understand this in laymen's terms? You're saying...a BIG, bass-only driver is limited...because it can only do bass, and isn't really suited to do mid-range, like would be needed for a loudspeaker design (as opposed to sub only). Then you say, smaller drivers are limited...because with their size, the only way they can produce "suitable" amounts of bass, is by "moving a lot" (and I assume you mean, the cone excursion...the amount it travels "in and out"?)
Now, you say those drivers are expensive... because as a driver moves in and out, more and more...to get that good bass; it takes a really well-designed one, to stay linear? You mean expensive, and well-regarded...like Dynaudio drivers? See...Arny seem to indicate, that too much excursion was the sign of a driver's non-linearity, or poor/limited design. You're saying, that in fact...if you want to get a small driver to produce good bass...you have to have a large excursion. You just need to do it well.
Look...now everyone is on Dynaudio's jock; because no one is going to stand there with a straight face, and say Focus 160s belong in a dorm room. Honestly...I take things too far sometimes, but shame on all of you. You knew all I was saying is that was out of line (want to look at the OP?), but you all wanted to argue the science...when "science" was never the issue. In case you don't want to peek back? Here it is OPost
I bolded the rhetoric, said it was garbage (which everyone seems to agree with...now); and I specifically said I'm not listing his handle, and let's not start a war with the guy. Now, use your heads (that's the thing 3 feet above your a**); someone had to go drag him in here, and incite this thing. They're to blame, not me.

















Please...a little respect; it's a stand-mount.
