" The Aleph1 cabinet is the only one that features a self-feeding closed loop that creates a perpetually infinite path in which the back-wave can propagate without ever returning."

Very nice design but audiophoolish stories as usual stand behind it. pressure wave cannot travel endlessly in closed-loop circuit becouse it also enters the circuit from the other end. It depends on acousical impedance ratio of both exits how retained is level and phase relationship of both wavefronts. If acoustical impedance is equal at the beginning and exit (almost impossible) both wavefronts will meet at the equal distance at the middle of the circuit and then travel to opposite exits where they meet again. Just another resonating enclosure is expected. It is shame becouse they will meet at the back of the transducer. If acoustic impedances are not equal, it will be just similiar to labirynth enclosure.

"The principle of the Aleph1 cabinets may appear familiar, but you have to look inside to learn the difference.
It's true the world renowned Bowers and Wilkins Nautilus speaker, introduced in 1993, employs a spiral design to address cabinet diffraction. However, it only does so for the low-frequency driver. Also, the Nautilus spiral is finite and terminates at the center, from which theoretically, the rear-radiation would begin to make its way back.
The Vivid Giya speakers feature spiral structures as well. It is unclear from my research whether the spiral is there for acoustic or aesthetic purposes (or both), nevertheless the spiral is either finite or "spills" back into the main volume of the cabinet in a way that doesn't address back-wave reflections with the same approach as the Aleph1 concept.

Sounds like bs to me...

Not quite but close.
