My room is similar to yours in size (lower ceiling) and I have a similar dose of room boom between 40 and 50Hz.

I borrowed my dealer's Quatros for an eval. With the bass contours set flat the major room mode was a good 12db higher than the adjacent frequencies. With a bit of tweaking of the crossover controls I was able to get the delta between frequency centers down to about 3db without any trouble at all. Keep in mind that Vandersteen recommends against using the controls to create a perfectly flat response. Rather the goal is to reduce the size of the peaks and troughs by an equal percentage (75%).

The bass out of the Quatros is impressive, but they still lack the ability to pressurize this room and provide "impact" with deep bass notes. The additional bottom end of the 5As should solve that issue... so that's what I have on order.

Since both speakers provide solid bass well below the 45Hz hump that you have in your room both will have equal ability to excite it. The bass contouring controls will allow you to effectively flatten that hump and hear/feel bass like you've never experienced.
