JBL 4435
1981
1996
No need to introduce the 4435 - one of the most recognized "shapes" of the audio world.
Also one of the most revered sound of the professional world.
Pity the trend since a few years isn't toward the equivalents of a 4425 but the usual badly setup self-powered Genelec.
It seems the more the recording formats evolve and get better (DSD & SACD), the more the vast majority of the recording studios get worse intrinsic sound qualities and monitoring systems...
