The first part was intended for you...stands and setup. The second part was intended as an "I don't agree" with Warrenh.
My point on the loud thing was that simply adding more and more power to the MMG's (or dipole panels speakers in general) is not always the answer to better sound, ie...if 100 watts is good then 200 watts will be better...and on and on. (never buy a used pair that have been run hard)
The small Maggies will play fairly loud, they will not play as loud as many other speakers, (conventional box, hybrid designs, horn designs)...adding more power will not get them there either...it "will" get them an early trip in for rebuild however.
In the end...your speaker system only needs to play as loud as you like to play it...your amp will need enough power supply to do this without clipping, you speakers will need to be able to do this without distorting...for "some" people, lower powered amps are fine with planers, others not... as confirmed by the above replies.
Some people move on from dipole planer designs when they have had enough of "the amp game" even though, they do like the speaker...it's just the wrong speaker, ie...no amount of power will transform a dipole into a monopole....which better fills their needs for bass slam.
