you are probably listening the box + room resonances together, so the low frequencies are probably reinforced.
try to listen it outdoor far from any wall, so you may take a better conclusion.

The driver parameters are correct, I only guessed the area and depth. Hornresp also cannot predict the influence of the surrounding area (e.g. if close to a wall). Have a look at my simulations of a much larger and deeper H baffle here https://www.diyaudio.com/community/threads/western-electric-ta-7331-a-baffle.390120/post-7121014
In room response may be drastically different, for the better. Maybe also psychoacoustics is doing its role, the peak may be euphonic.

Since I found LORDSANSUI's horn plans here, I developed a deeper fascination for horn speakers. Those weird creatures have fascinated me long before also due to their sound, but playing around with CAD models and Hornresp is too much fun. You can find the thread here: https://www.diyaudio.com/community/...loudspeakers-plan-hornresp-integrated.391237/
What I learned about horn speakers so far in a few hours of research is that you need a quarter wavelength horn at least, which for low frequency is pretty long. A quarter wavelength for 30Hz is roughly 3m. This is difficult to fold into a tiny horn and a W-bin has way too short signal length inside to make a good bass horn. Also, you need a mouth circumference of a quarter wavelength, too, which is also not possible with your size constraints.
Still, I find W-bin horns attractive looking due to their symmetry and toyed around in CAD to fold more length inside. Maybe something like this could work?
The extra fold creates way more path for the signal, but also increases size.
Currently the size of the thing in my CAD is 1.8mx1.0mx0.9m, driven by two 15" and given my input into Hornresp is not too stupid, it goes down to slighly below 40Hz. Surely could be better with some optimization, but for a very first attempt, probably not too bad. Length of the signal path is 2.7m and each horn mouth has 3.2m circumference.
No way I'm going to build this since a wardrobe would need to go in turn.

Its a monster! I now also looking and calculating ported box. Maybe is to small space for what i want out of this horn. I think deepth is the biggest problem.
If you make a ported box,and make a frame around front side,like in H frame design,what do you get? For example,dimensions looking from front side 125cm widd,65cm high,60cm deep,inclouding boards.
So rear you have box of 290 liters,you put 4 ports on front board where woofer is,and around that board you have 20cm deep frame. What the frame do to sound,if there is any impact on the sound.
Box with this mesurments and this woofer have:
Fb=40Hz
QL=7
F3=39,58Hz
