I know the PSB Image 4t but not the 5t. I am listening to a pair of Aurum Cantus Leisure 2s at the moment. (My bedroom is less than half the size of yours but that's where I'm listening to the ACs.) Note that my AC's are a version with upgraded crossover parts, however.
The only Paradigm I can compare with is the Titan, but this was my old bedroom speaker. I don't want to go back to it now.
IMHO the Aurum Cantus is so much better than the PSB there is no contest. The tweeter is especially superior, but that doesn't mean the bass is not satisfying. It goes low enough for me, and my small room limits bass severely. I intend to try the ACs out in my main rig, which is in a room about the size of yours, and I expect to be very happy. I think so even though the Aurum Cantus is much less efficient than the PSB and a lot smaller. If you expect to be having a lot of dance parties in your bedroom, maybe the 5t's are a better choice. But if you want to relax, I would say the Aurum Cantus is for you.
