All Bose speaker systems are not designed to be direct radiators...

Comparing their FRs to that of any other loudspeaker, including dipoles, is meaningless...

The difference in FR between 13kHz and 20kHz is around 2/3 of an octave...an octave being eight whole steps (or notes) apart, that means the fa-so-la-ti-do of that final octave rolls-off...

But then again there are no notes at that point in the frequency spectrum since, as we all know, most fundamentals produced by musical instruments and the human voice pretty much top-off in the 3.5k to 5kHz region...most everything above is harmonic in content...which doesn't mean they aren't important, just not quite as important as the numbers themselves would seem to imply.

Think in terms of polar dispersion...similar to microphone response patterns...from omnidirectional to hyper-cardoid and any permutation thereof. Obviously this is an oversimplification and generalization, but comparing them is really useless as they all do their jobs, but in a distinctly different way...

Sounds to me like you're trying to rationalize the poor performance of the Bose speakers.

It aint worth the effort. Even properly setup they're lacking IMO.
