Hi Have to confess straightaway that I'm no Bose fan, either in terms of sound quality or marketing/holier than thou attitude. However, every so often I pop into my local Bose dealer just for a laugh because he pushes absolutely nothing else for discrete home cinema use. What I can't get my head round is this Acoustimas thing which, according to the dealer, isn't a sub-woofer and can accurately position sounds in any part of the listening area. I'm on a steep learning curve on subs but isn't the Acoustimas a sub by any other name? Or am I missing something?
