Ah, thanks. Don't know why I was thinking dominant resonance was between the top and bottom walls.
A pair of dual driver ri-poles has been on my to-do list for many years. Think I could get decent low frequency extention with 4x 10" drivers (0.43 Qts, 43Hz Fs, 10mm Xmax)? I don't need a lot of spl and have plenty of EQ and power.

I finally finished my build, was on vacation in the mean time. I included some build pictures and one where the finished subs can be seen with my setup. While i remember that Jazzman once called the build of a RiPol "easy" i had quite some challenges with it. First of all the 7cm radius cutouts for the magnets were too small for the router i had and therefore needed some help from a local carpenter to get them done. In the end i still had to use a rasp to shave off a bit conically to get a flush seal. Due to the length of my design i also had to include another metal bracing at the back to get the two chambers to seal flush. Otherwise my only real "problem" is that even though i sanded everything to 240 grit, the spray paint turned out more like 160 grit and i could not sand it the top layer without scratching it. Maybe i'll give them a different finish in the far future.
Now about how they sound with my Fosi ZA3 and the Yamaha V6A. First impression was underwhelming to be honest, with a distinct "where is the bass?" feeling. After adjusting the levels and listening to a few more songs this turned to excitement as the bass was actually there and very "clean" at that. Overall way less boomy than with my Versacube which is great as the rest of the songs in turn are more clear as well. While the configuration in my setup is certainly not perfect (maybe i'll try putting them under a coffee table in near field in the future) the bass does not come from a distinct place anymore and blends great with my speakers. Everything sounds full and balanced, my only nitpick is that they do not seem to pressurize the room (which to be fair Jazzman warned me about) so there is no tactile feedback to the bass.

Nice idea ! But yes : you need some circa 40 to 60cm spacing free at the rear, so you can't put it against the wall...
That said : why not opt for a similar principle for a coffee table instead of a console ?
