Why not have a neat compact pair of floorstanders and have the wider frequency range built in?
Because stand-mounted speakers on decent stands sound better than compact floor-standers.
Compare the Kef R3 stand-mounts vs Kef R5 floor standing speakers. The R3 has a 6.5" driver, the R5 has a pair of 5" drivers. The R5 will go a bit louder except you lose bass frequencies, whereas the R3 will be better balanced and go down to lower frequencies more comfortably.
IMHO stand-mounts also look a LOT better in most living rooms, which let's face it is where they're going to live for most of us
So, if you still need floorspace to put stands for the standmounts... Why not have a neat compact pair of floorstanders and have the wider frequency range built in?
