Well,I decided to go for the Logitech speaker set up for my KN7000,wow,they're great,they have really enhanced the sound with a fantastic full bass;that is a serious sub-woofer!I love those reversable stands on the satellites,which I've done and now have them wall mounted(more holes in the wall the missus moans!).So thanks to all who made me aware of these great value for money speakers.
Cheers,David.
