Is it really lighter than it should be as for now, or you just want the mids a bit recessed? What kind of music you mainly listen to?

Salas, I listen to all kinds of music, classical, rock, pop, jazz. I am a pianist so I often use piano music as a reference. I think the bass sounds a bit scaled down and dry compared with what I am used to, I guess I want a little more "flesh". It is mostly when listening to pop/rock and not so much listening to classical music. I will post a picture tonight from the inside of the speaker.
This is the coil I use for the bass:JANTZEN-2005 - Jantzen Wire non-ferrite cored coil 2,500mH 0,268Ohm 1,20mm - Europe Audio
It doesn´t look like that in reality, it is the high coil I use (ealier picture).
The RDC is a little lower than a 2mm air coil from what I know but it should be a very small difference.

Starre, I also play piano. I think it is a very important and satisfying instrument to get a loudspeaker to reproduce faithfully.I think you will find that most of this happens above 100Hz and not below. It is therefore susceptible to problems of midrange balance, and room placement. The 'weight' is around the 150-300Hz region.

Hmm. There was a 2mm air coil we used. Anyway, I think that ultimately you will need to choose a precise coil value for your ears, room, and system by listening. If there is a way they make you a multi tap coil with 2.6 2.7 2.8 2.9 3mH taps you will be a happy man.

That may mean closer to wall to get luck before tampering with the diffraction step coil.

Absolutely. If the speaker is voiced well then the room should be looked at first.

I will try to make the cabinet more sealed, I have the baffle on wooden plugs right now so maybe it leaks too much air making the bass weaker, how much does a leak affect sound, anyone with experience?

In a bass reflex too much. A simple test is you push back the woofer with one hand first, and you press with your other palm the port's mouth sealed the best you can. If you leave now the woofer alone, it should remain sucked in if there are no leaks.
