Okay. So if i get a port, and do the following, i wont necessarily have problems with the 1st port resonance? I looked at getting a 7cm diameter vent, but the problem is that the air resonance is peaking at 35 m/s. Question is then what is more important.
That depends from the level you will drive the woofers with.Question is then what is more important.
7 cm seems a bit low, but may be ok with big roundovers.
Alright yeah. Its only going to get like 60-70w, but the 1st port resonance get down to about 2500 hz with an 9 cm wide port
Keep in mind, the port resonance relates to the port length, not diameter!9 cm wide port
Those driver is not suitable for two way, look at 10db scale, peaks in midrange have +-5db nonlinearity, it will not sound nice in two way. Those woofer reguire minimum 2nd order @250Hz and crossing higher than that is not very nice, even going two way you will need very complicated crossover which is probably twice the price of your woofer+tweeter, Why not look at Troels Gravesen site, he have many nice designs with that woofer? E.g. http://www.troelsgravesen.dk/Faital-3WC-10.htm
If you realy need something extremely cheap go woofer without crossover at all and just add 1uF in series to an tweeter you find suitable for you, e.g. https://www.audiophonics.fr/en/twee...dome-tweeter-50w-8-ohm-93db-o30mm-p-1223.html

Ill just stick with the woofer, thanks. The project is not something i want to make complicated. It is an outdoor speaker, that i want some decent sound out off. I already have a speaker with raal 70-20xr am, purifi mid and audiotechnology 12", so really what im looking for is just something decent for the garage and outdoor.
Not directly, but diameter-squared (or, rather cross section surface).but the port length relates to the port diameter
