Of course the issue here is not so much time alignment as it is whether the physical structure will allow/facilitate decent LF. And of course "framed" structures eat some LF and create a +/- unpredictable LF environment.
Two of many questions are, whether and how to "reinforce" a wood-framed, raised floor and whether to try "shaping" the LF in some way. FWIW, most raised wooden house floors can be reinforced considerably, if there is access under the floor, and some floors can be reinforced from above-the-floor access.
The best large room bass I have heard did use "shaping'; but so did some of the worst LF I have heard.
Moving around in a room stomping, jumping up and down, yelling and clapping hands loudly can tell a lot about that room. But finally injecting real LF always tells far more.
My present listening room is on a raised floor, and it absolutely eats LF, no question about it. I have been here two years now, and I have simply been too cheap and too lazy to deal with it, so far
OTOH, it somehow works out that all masonary/concrete is also a royal PITA for hi-fi, so I suppose it is nice to have some give in the surroundings.
