Any in depth Reactor reviews or users here?

That's why I said that it depends on your personal preferences regarding the SQ

I just don't happen to like bass boosted frequency response because I have got used to having a flat frequency response in the bass. It has nothing to do with how low the speakers can go. The Reactor's bass response is not flat in real rooms as we can see from @eniriop 's measurements and that is completely as expected since there is no room correction feature in the Reactors. That is totally fine if you happen to like that kind of response. It's just not my cup of tea and therefore I'm trying to figure out some way to get a flat response.

I guess I didn't expect that the Reactors would have this much power in the bass. So much power but no way to control it.

I think that what your ears have been used to is not a flat frequency response but rather a rolled off frequency response under 300 Hz (see link below and also hifi plus review below). There is nothing wrong with this !

But maybe after a while you might get used to the flat bass response down to 20hz...and ultimately find that the Wilson Benesch Vertex lack that kind of low bass response... 
It mainly depends on the kind of music you listen to and how large or small is your listening room. 
I bet if you go to any kind of live concert playing modern jazz, rock or pop music you'll hear much more of this kind of low bass ...and you'll probably love it...

Here is a (very favorable) review  of the Wilson Benesch Vertex in Hifi Plus:
" It delivers good bass for a loudspeaker of that kind of design, and is ideally suited to work in small rooms of mostly brick; the sort we British pay far too much money for. In a bigger space, or a room that doesn’t have the same construction methods, the bass rolls off honestly and accurately. But it rolls off. In truth, I would rather have a loudspeaker like the Vertex that rolls off predictably than a speaker that introduces its own distinct sub-100Hz booms to make the speaker seem bigger than it really is."
