Actually, to be a bit more exact that honor would have to go to the L100 as far as sales figures go - and possibly keeping JBL solvent and intact
Best too as far as fame, recognition by more folks - even those who could care less - and changing the audio world as well (and how we listened to music for decades)
From a purely historical perspective most decidedly the most considerable conspicuous and influential
I try to avoid the word "best" whenever possible in conversations like these - "most" would be more appropriate for me
