mtrot,
all ported speakers work that way but speakers with larger boxes get lowers before dropping off. The subject of this thread the 228be is on example and it goes down to 60hz before heavy roll off starts.
The Sophia 3 is another example. Even though the 228be’s two 8” drivers have 20% more surface area than the 10” of the Sophia 3, due to the large box of the Sophia 3 it goes down to 50hz before dropping off (resistance and other things at play here but box size is #1)
At each point the port picks up where the drivers leave off. Room gain most likely adds 6 db of bass in the low 30/40hz and you can see that the Sophia is down about 5db at the port and the 228be is down at 6db.
In listening to both the Sophia 3 has stronger deeper bass than the 228be. The 228be sounds rolled off to me. But with subs crossed in at 60hz all of this goes away. The 228be has much cleaner highs and the mids are more transparent and natural imo. I believe the 228be with subs (picture of my setup in my profile) is better than the Sophia 3 with or without subs.
This more or less is how all ported speakers work. Larger boxes are always better. The issue with the Kanta IMO on paper…. Is that the box is pretty small and the port is tuned pretty hot. At high volume it will be limited and chuffing could appear. I think at normal volume they will be 100% fine in every way but next to a large speaker in a large room they will come up short when played loud.
Another approach active speaker when the power is increased in the low bass to get flat down to 20hz. This is effetely what is burnt done when you high-pass in subs. It turns the speaker into a 4 way with active bass. The kicker is you as the user then kind of become the speaker designer which is not for everyone.
Since we are on a harman thread so to speak harman claims that in their subjective data bass extension attributed to 30% of the total positive opinion of their blind test. Interesting for sure abs it show how important it is to get the bass right.
So nothing wrong with the Kanta just point out as a smaller speaker it will be more limited in shear output. Rear wall placement could be more critical too.

Video of audioholics talking about how good the bass is on the Kanta. Notice how close they are to the wall. 24” maybe and this is probably where they need to be for strong low flat bass.
