four ledger lines low Eb to three ledger lines Ab above middle C (with an alternative available). 
A few high school students have "pulled it off".  Many others have "played at it" fairly  well in performances.  It's quite a bit easier to play with a "bass" (Eb/F) tuba than with a contrabass (BBb/CC) tuba.
