Booming and resonant, it exploded (10)
I believe the answer is:
stentorian
'booming' is the definition.
('stentorian' can be a synonym of 'booming')
'resonant it exploded' is the wordplay.
'exploded' is an anagram indicator.
'resonant'+'it'='resonantit'
'resonantit' anagrammed gives 'STENTORIAN'.
'and' acts as a link.
(Other definitions for stentorian that I've seen before include "booming" , "Strident" , "(Of a person's voice) loud and powerful" .)
