   IF there is nothing else wrong, the increase in wattage   
   will have NO effect on the sound of the speaker, except...

   Increasing the wattage of ANY of the resistors will   
   not change that sound of the speaker, but ...

   I think you, unfortnately, standa a good chance of having   
   something else wrong with the speaker, like possible a   
   blown driver. While I do not have the older 801 schematic   
   here (the one I have has no 0.47 ohm resistor), it's pretty   
   like that enough power through that resistor to blow it up   
   happened at the same time as a LOT more power through   
   something else.   
      
   Another possibility is that when a driver went, the topology   
   of the network was now changed sufficiently that MUCH more   
   power than normal went through taht resistor, and it failed   
   AFTER some other component failed.   
      
   But while, if everything else in the speaker is okay, upgrading   
   the power on that resistor will have no effect on the sound of   
   the speaker, because something else may be broken, replacing   
   the defective resistor with ANY wattage may well not fix the   
   speaker.
