Even with SPLs within their capability the small speaKer is working so hard, is so much closer to its limits, that the stress is easily heard. Dynamics even at lower levels (80db) are lower, distortion is higher, the amp is working harder, it all adds up.
Progress in the speaker industry has essentially meant smaller packages, with a huge tradeoff of ease, naturalness, real life dynamics, distortion (manifested as a more stressed, harsher sound).
You can't beat the physics, there is no free lunch, these are expressions heard frequently within technical staffs in high tech, defense, aerospace. They apply just the same to audio.
But how did we get here, folks might ask? Marketing, magazines, wife acceptance factor, among other factors.
Follow Ups:
Acoustic impedance match of speaker diaphragm to the air it connects with probably plays a part.
See 1st para, here:
The horn is the acoustic transformer.
The compression driver is a very efficient and low distortion motor to create the wave that the horn then matches the impedance to a better degree than a direct radiator driver.
