Sorry, couldn't agree less! If the room is big enough for floor standers (and the OP's is), get these. They don't need to be large Many take no more floor space than stand-mounts) and they don't need 3 drivers but the better ones do.
However I agree that nice speakers require high quality enclosures and these are cosrly. That's good reason for getting speakers that provide the bass you need, rather than increase to your enclosure cost by adding subs. If you go the stand-mount on stands (never attractive), yes they are less costly, but they are likely to lack the bass most people want, so you soon start thinking of adding subs. Look at the result - smsll speakers on ugly and costly stands, more costly enclosures (subs are never attractive), more amps, more drivers, more cables, less floor space, less easy to set up properly. Get good speakers in the first place that look nice, sound great, provide the bass you need and you'll be happy.
