Keep the mini-x’s, better than the Focal or dynaudio mentioned above IMO. You can’t compare the mini-x to the 718’s from the past unless the 718’s had the DMD tweeter which is a game changer. I have and still own many Usher speakers, the later 1’s with the DMD tweeter. I have the Usher x-towers which is a $14k floorstand speaker consisting of the mini-x plus the woofer modules with their Eaton 11" woofer. Before this I owned the Mini Dancer ii’s with the DMD tweeter and other Usher Dancer series speakers with their silk dome tweeters. I just moved to a new house with a 16’ x 13’ room and will be using the mini-x speakers without the woofer modules if I put them on the long wall or will use them with the woofer modules if I put them on the short wall. I had the top of the line Totem speakers before going to usher and they were also very nice speakers.
As for ported speakers, I like front ported speakers so they are more room friendly. You can still plug the ports to fine tune them.
