Yup, I saw that too and was blown away by the claim - got pretty excited thinking that this may be the perfect one full range solution......until I realized how he claimed the 20-20hz.

They dont look like good value to me

Note that in the graph used to support the 20 Hz claim:



we are presented only with cuves of the terminus & the front of the driver separately, with no summed response. Sure the mouth may go to 20 as shown, but what is it's phase with respect to the front.

For instance on the terminus curve you can see a series of peaks (~120/240/480...). From 1 peak to the next the phase rolls thru 360 degrees, which will cause a corresponding set of ripples in the combined response. The same happens lower in frequency as well.
