Using Boxplot, some drivers have a max power curve that dips rather
low towards the lower freq's, while other drivers are "allowed" spec
power at all freq's. One such odd drive is the Delta15 that you use.
I'm assuming that for the given driver params (Xmax, Vas) and box
size, the Xmax of the driver would be exceeded if power was above
the curve. Is all this correct?
Thx, Chris

Isn't that sort of bad, then? Too much content at the wrong freq.
(mid-band, though) would wreck the driver.
