32zp18p - simple sound upgrade??

Straightforward question ..

I have a 32zp18p (which I am growing to love - dirty screen effect being the only real issue).

The set sounds ok using onboard 5.1 decoder and woofer thro' bundled toshiba speakers. However I was wondering ... is it worth investing in better sat speakers... i.e. Kef Eggs or Gallo micros, without improving the woofer.

Would this simply improve the decor of the room without improving the sound .....?



Forgive me if this is a silly question ... but your views would be most welcome ....
