My last build was a closed subwoofer using a Dayton Audio Reference RSS265HF.
I like it a lot, but I want to test a setup where I combine the RSS265 with two 10" passive radiators to compare.
It seems like all subwoofers with this setup have a cube shape. Is this the optimal design, or is it used to make the subwoofer as small as possible?
I have found that the passive radiators should be installed on opposite sides of each other to cancel some resonances.
My first closed build
An idea I did play with for a ported setup - could skip the port and add a passive radiator on each side (adjust height..)

It's the most material-efficient shape for sure. It also makes sense to have the PRs opposed for the force cancelling benefit, since they will be making larger excursions at lower frequencies, and you're likely to be using two of them for sufficient Vd.
I just built a single driver dual PR box. The PR are currently mounted 90 degrees a part , instead of 180 opposed. The crazy thing wants to walk all over the place around Fb 🙈🤓
