Many Classical recordings from the first few decades of stereo were mixed with following assumptions in mind:
1) Listeners would be using AM Radios
2) If using a Hi Fi system, speakers would be bookshelf models, in small rooms, with very limited bass potential
3) Vinyl would be the source, and dynamic range, particularly bass, needed constriction due to groove spacing issues.
It was interesting to see the return of intentionally bad mastering reoccur in the 21st century, as the assumption was that listeners would be using iPods with free earbuds
