The biggest issue with prefab ported boxes is they’re tuned way too high (about 40Hz)… unless you like that type of sound. Do you have the ability to cut a hole for some PVC pipe perhaps? I’ve had very good luck in the past getting a slightly larger sealed box, then cutting some holes for some PVC pipe to tune it to about 30-32Hz.
By the looks of the box mentioned above you could cut a hole or 2 for some 3” or 4” PVC with a hole saw on the long “leg” side.
