500w head on a 400w cab

[GeezerB]

I have the opportunity to buy a hartke ha5500 500w / 4ohms amp at a good price. I already own a hartke 215xl 400w / 4ohms cab, when I go to the hartke site, it is suggested to plug the amplifier into a 600w / 4ohms cab. Can it blow up the speakers?
thank you

 

[Stumbo]

Yes.

You can blow up almost any cab with almost any head, even if it has a lower rating. Use your ears.

What Buldog said. Use your ears, and back off your volume if you hear the speakers getting pushed.
