Removing the speaker, top of Ti needed

[John]

Does anyone know what mfg the speakers are in the Ti 550, and how I can 
get to them. If it means taking the whole computer apart, I will. I 
have the disassembly instructions. Or are they incapsulated in a black 
box and glued?


Would anyone be willing to donate/sell me the top half of a Ti, if that 
top half is in unserviceable (ie, cracked/broken) condition (ie, 
cheap/inexpensive)?


Can I upgrade to better speakers? I know I would have to match 
resistance/current draws.



Thanks!

John
