It has everything to do with "high end". Or in this case meaning "high end LARGE external speakers".
You can "test" any speaker with "ULF BASS sound files", however if a laptop speaker designed parameter falls outside the range of the intent, desisgn, and specifications...., then the outcome is normal.
Then the outcome is as expected or referenced — not normal — and the test was successful. You seem not to grasp the concept of testing.
You cannot put a 500 pound person on a ladder rated for "250 pounds max" and declare a 'failure'. Test it for same, yes.
You will most likely declare a failure of the ladder, possible an ankle or a wrist, too. The test would then confirm what the specifications told you. Not sure what "Test it for same, yes" is supposed to mean.
Low Frequency Range Test (10-200 Hz)
"Because of their increased wavelength (nearly 20 meters at 20 Hz), high output at low frequencies usually requires large drivers (subwoofers)"
Clueless to what point you're trying to make here.
