Stagger around with the Speaker? (7)
I believe the answer is:
tweeter
'the speaker?' is the definition.
(tweeter is a kind of speaker)
'stagger around with' is the wordplay.
'stagger' becomes 'teeter'.
'around' means one lot of letters goes inside another.
'with' becomes 'w' (abbreviation).
'teeter' going around 'w' is 'TWEETER'.
(Other definitions for tweeter that I've seen before include "hi-fi unit?" , "Chirpy type" , "highly effective in reproducing sound" , "Poster of short message - little bird?" , "One may follow another" .)
