Have to remember Focal tioxid tweeters are $20 and the Accuton/Scan speak mids are $175. So what are you paying for reallyI'm not contesting the point you're making & I second the usefulness of Focal's built-in DSP.
However the point about pricing applies all around; while the ceramic drivers alluded to are slightly more expensive than you note, the Focal "W" driver are similarly priced. For that matter, the standard ATC drivers are only slightly more costly. The beryllium tweet OTOH, is VERY expensive (or was -- focal doesn't seem to want retail sales anymore).
But, it's good to ask ourselves the last question every now & then: "What are we paying for?" The design (choice of units, xover, cabinet design) & box maybe? When a manufacturer hits upon a "good sounding" design, the price escalades fast regardless of component cost maybe?
