fuse blew on sub

[robina_80]

ive got a tannoy ts12 and i was listening to music quite loud my sub settings were cranked all the way up eg gain knob was max and the xover freq was half way, and all of sudden my sub stopped working and it was the fuse in the sub that went and after that it was OK(ive learnt my lesson not to have it too loud in future) but im wondering why should it have stopped i thought it could handle massive bass thats why i got it
