i'll give freddy his credit but draiman can get low, freddy couldn't...he was a tenor and although he had a good vocal range, it was on the high end and with heavy music it's worse than most hair bands.
Please, Freddie's "preferred" vocal range went from F2 (Bass) to F6 (Soprano High). He preferred the "falsetto" of F5 (Tenor), especially after he started smoking. Mind you, Freddie's vocal range was 3.5 Octaves.
EDIT: Here is what I needed, from Queen's latest book.
Low Register:
F2, G2, G#2, A2
Upper Chest Register:
C5, C#5, D5, Eb5, E5, F5, F#5
Head Voice/Falsetto Register:
G5, G#5, A5, E6 (No, Bb5, B5, C6, C#6 & D6) - Notes hit Live.
