Guys
Thanks for the quick replies, best go and turn them off then!
If you think they will sound ok with the module then i`ll get one. I just didnt want to get a module and find out that its the same as the Yamaha system thats all!
Im not a hi fi guru ( can you tell

) but i can recognise the difference between astounding sound and ok sound.
I`ll email Bose asking which model i need and go from there.
For interest, are there any other makes of speaker of a similar design that outshine the Bose Acoustimass 20`s?
Cheers
