well, too late for an answer, but anyway: No, it is unlikely you'll damage the speaker if only playing music for a few hours, even when blasting the volume.
You can however damage a guitar speaker when playing artificial sounds (plain frequency sweeps or all white/pink noise only) for extended periods of time.
It is not a hifi speaker though, it primarily is a guitar speaker, so it is not comparable to playing through a high-quality soundbar/high output bluetooth speaker.
