This has sort of been touched on in a recent thread and it's got me thinking about my own setup. At the moment I have Mission M74i floor standers as my main LR's which are driven as 'small' from my amp. All frequency's below 80Hz are sent to my B&W ASW675 sub. So are my floorstanders unneccesary and would I be as well off with smaller bookshelf / sat speakers? I'm not convinced I'd get equal tonal quality from sats though. I have thought I could talk the missis in to letting me get an SVS PB2-Plus, by telling her we would be able to replace my big floorstanders with nice little wall mountable ones if I had a larger sub!
