Hi Johnny Be Good,
As it turned out because the weight is low in the M100s we felt it was fine to offer the outriggers as an option. The LFR1100s have more weight up top with the rear components. That said I am not using the outriggers on my own LFR1100s as I prefer the look without them and they are certainly stable enough.
The comment about "where applicable" is to cover the fact that there is no midrange driver in the M50 when we are talking about our line of tower speakers.
