From what I learned, the problem is that this type of porting does help extend the frequency response down to 50Hz but beyond the response drops down steeply. So, a bass note that is moving around this spectrum will have an uneven perceived volume response. This makes it much harder to judge and obtain a solid and even bass line.
This would be a big 'NO' in electronic music employing sub-bass or certain instruments that go down to 20Hz like pianos and organs. In other words, a kick bass' energy in the 30Hz region might be 12dB lower than the 50Hz region, therefore making it a complete mess when the mix is listened in a different mixing environment.
Some other porting anomalies include, resonant frequency which a test signal will not show because it is different than music waveforms or percussive sound with fast transients, or ringing of the port that can cover a fundamental frequency. Furthermore, the port can resonate at various frequencies causing smearing and artifacts along the whole frequency spectrum not just low ones.
In my opinion, for serious mixing, it is better to have non-ported monitors coupled with the sub and a treated room not only with acoustic foam but bass traps also.
Now, this is expensive, but well worth the investment, if this is a business you're relying on.
A good example is the timeless popularity of Yamaha NS10's which are not ported. Of course, it is impossible to judge the bass just using these but the midrange comes in focus amazingly well due to less above mentioned artifacts. As Bob Katz would say after all: 'Midrange is the key'

While in general I absolutely agree with you regarding small speakers with badly executed reflex ports, but in this particular case this doen’t really apply. Look at the size and volume of cabinets of these Focals, look at their powerful amps and look at the size of the woofer. This is bot a small speaker trying to sound bigger. This is a serious big speaker with very low distortion and high continuous SPL capability. In room you’ll be able to achieve full range at serious SPL with this speaker. So you will not experience issues like you described above. Mastering palace (Dave Kutch) use smaller version of these Trio 6be for mastering purpose for major lable top 40s hits, so with these being even more powerful, bigger and more extended, you have nothing to worry about...only whether your room is good enough.
