Did my Marshall BV cab just blow ?

I’m sure it’s the jack assembly. All four speakers won’t go at once. If you don’t have a multi meter just touch the speaker tabs with a 9 volt. That will tell you if the speaker is bad or not. If the speaker moves and makes a sound it works.
 
Ok guys . So I punched the cab a few times . Now it’s working. What’s that mean is wrong ?
