I'm designing a small enclosure (100 in^3) and putting 2 3" drivers in it. I tuned them in WinISD and was wondering if this is a good tune. I have the Transfer Function Magnitude graph, Air velocity graph, and cone excursion, along with the box size, tuning frequency, and port size. The drivers are Dayton Audio DMA80-4 3

Well, the under damped 'bump' up in the vocals bandwidth (BW) is considered unacceptable except in certain situations, so ideally needs to either be flat or rolling off depending on the app, so what is it? Till then the other plots are moot since changing the response will likely change them.
FYI/FWIW, with a ~0.4 Qt, a T/S max flat alignment is Vb = Vas, Fb = Fs, so as your plot shows it's way too small for two.

A little more bass? Way too much as GM suggests. 1 dB maybe, 4-5 not good.
1.6 lire… what 3” are you using that you can fir 2 in such a small box? It won’t go very low.

The drivers are Dayton Audio DMA-80 4. I guess I should have also mentioned I'm going to pair it with a subwoofer, so I tried to get the f3 just below 120hz so the sub can handle everything else below. I could probably squeeze a bit more room, I just have to make the sound bar wider, which won't be hard.
I looked at that driver — optimum for a miniOnken-style tuning would be 1.4 litres. You can squeeze 2 in but it doesn’t go as low. These works best with slot vents.

Slotted is what I was planning on doing. If I paired them with a subwoofer and get the f3 to around 120hz, would the frequencies blend enough?
