Is it possible to upgrade the speakers in my laptop?

Hopefully this isn't out of the area of expertise for you guys. The stock speakers on my laptop are crap and I'd like to swap them out with quality ones.

I'm able to disassemble my laptop and replace the components, but don't know how to find good quality aftermarket laptop speakers, if such a thing exists. Does it?

My machine's a Toshiba Satellite e105-s1402, the speakers are about 1"x.5".

EDIT: I found that later models use Harman Kardon speakers, if I bought an OEM pair would I have to splice wires to install them? Do they all use the same connectors where they attach to the board?
