Yes, speakers are important. Also, a lot of midbass is lost by cancellation with the floor reflection. I assume that’s one reason that many recent floorstanding speakers have multiple woofers (to spread out the effects of the reflection), including at least one woofer very close to the floor (in which case there is no cancellation).
Distance from the front wall is also an issue, and vendors of pro monitors like Genelec offer advice on positioning to reduce this problem.
Some listeners prefer the typical midbass hole, which can be perceived as "tight" or more detailed bass. And I’ve always suspected that one reason audiophiles prefer female vocalists is that the lack of midbass doesn’t much affect reproduction of their singing. (There are other reasons for the preference, I’d guess, but maybe best not addressed in a family forum. 😉)
