Analog audio port output

Hello, I was wondering, what are the analog audio port specs. I know its primarily meant for headphones, but is the on-board preamplifier capable of driving miniature passive speaker 8ohm/0.5W(1W peak)?
This is a datasheet of the speaker I would liker to connect directly to 3,5mm jack port, if possible: http://www.tme.eu/cz/Document/a7488e8a1 ... -8_DTE.pdf
