Can too low of a frequency damage my speakers?

[cradeldorf]

I recently upgraded to a Marantz 1501 surround sound receiver and on the specs it says frequency range 8 - 20khz. When I put the movie Rango in theres a part during his first encounter with the snake, right after when the snake says "but we know differently don't we" it hits a super low note..and I'm just wondering if it's close to wrecking my speakers. I don't know how low it it but it's damn low.

Edit: never mind I was looking at the analog inputs. It says 20 - 20khz on the output. It still shakes the house harder than any other movie track I have though.
