I have a different take, The SCM 11 are not bass light or bass shy, they are actually the "warmest":(the most bass in relation to the midrange) of ALL the small ATC 2 ways. So the bass light impression of the SCM11 shoild not be, I suspect its all "room" related. The fact that sub seemed to "solve" the issue emphasizes the point. There could be multiple reasons for this, but lets start with the basic Idea that a room under 30 foot in dimensions is incapable of supporting a 32 hz wave (32 hz = 35 foot long wavelength).
Most speakers will be bass light in a normal size (12-20foot dimension) room. This is NOT solved by stand mount vs floor mount, or other myths. This issue is msot often solved with multiple small subs used a low level. 4 small 10s would not be wrong- they can even be small cheap subs. Without high passing your SCM11, adding subs [that are not ported] low passed in at somehwere around 60-90Hz could be the best solution. This would provide even bass throughout the space and also enable you to set the balance of sub to main to your taste. I would not get overly concerned about LFE unless the min application fo these is film.
You will get quite a few with different ideas here, but this idea is one of the solutions we put in play in studio control rooms all over the US when they have the same problem, small dimensions.
