If the manufacturer could have made the speaker better by removing the port cover, why do you think they didn't?
Nothing good will come of it.
I will agree with this statement, but I have a few more points to add:
1.
This speaker doesn't seem to have a port. It uses 2 woofers on the front and a passive radiator (or 2, I can't tell). This functions similar to a port in terms of how it can allow for more bass output, but they can actually be made waterproof. Given that this speaker has an IP rating, we can assume that they aren't using a port.

2. A quick explanation on passive radiators: They are like speaker drivers, just without the magnet and other "motor" components. They rely on having air pressure in the speaker enclosure in order to move, and by adjusting the mass of the passive radiator, you can tune the frequency at which it resonates.
2b. So basically, since this speaker does not have a port, and is designed to use the passive radiator, you really shouldn't touch it. If you were to cut out that passive radiator, you would destroy the speaker.
3. Like most modern bluetooth speakers, this one uses DSP in order to get the desired sound. The DSP will have been optimized for use with the passive radiator, and removing it will obviously change that, and not for the better.
So finally:
If you really want more bass, you need a bigger / better speaker. It's just physics. Creating sound requires you to move air, and there is a limit to how much air you can move with a small speaker. If you are set on bluetooth speakers, I would recommend JBL as I personally quite like their sound. However, JBL tends to not have a super-crazy-bass-over-exaggerated sound, as having that sound just doesn't sound good to most people.
So in conclusion, you have 2 options:
1. Get a better speaker. I personally haven't heard the speaker you are referencing, but given what I see in about 1 minute of googling I would probably find it to be lacking in bass compared to what I am used to... (Of course, I am used to a system which is capable of sub-30hz bass at the levels I listen at) This is probably your best option, if you want more bass.
1b. So echoing my above recommendation, I like JBL's bluetooth speakers. Alternatively, if this is not a portable application you could go for something else, and if so you can look around here to find recommendations.
2. Reset the equalizer to flat, and allow your ears to become used to the sound. When we listen to a speaker system over a period of time, we get used to the sound of said speaker. If you listen to a speaker with boosted bass, over time you get used to that sound, and if you then move to a speaker with a more "neutral" tuning, then the "neutral" speaker will sound like it is lacking in bass. --- However, if you listen to the neutral speaker, over time you will get used to its sound.
