They have better quality drivers and a better built cabinet.
While it is not a head and shoulders difference - this is how
the S30 sounds to my nit-picking ears compared to the BS22.
They sound more rich and realistic to me. They have a more
detailed midrange, with better definition > and a more tight
and controlled bass > and while the BS22 tweeter may sound
more vivid, the S30 tweeter has more definition. > Also they
image better to me, and have a more focused central image.
I was not talking about Amazon shipping, Cambridge is global.
Look over at the right side of the page > there is a dealer in
Portugal, contact them for some info.
