Closed box, Port-less speakers

Are there any closed box, port-less or otherwise uniquely designed speakers that can rival the sound and quality, imaging, soundstage, articulation and smoothness of the ref 3a de capo's, opera callas, totem model 1, sonus faber's, etc etc etc? I know this is a bit like beating a dead horse but I have been unable to find speakers that are designed to be positioned against the wall behind it that performs anywhere near the quality of the aforementioned speakers which do not require this positioning.
