You're DEFINITELY going to run them as "small" on your prepro! You'll also get the best dynamic ability from them by using them in a smaller space, yes. Also, improvements in "solidity" wsill be had when you sit closer to the speakers, proximally, than you do to the room boundaries! (basically a small room setting, or close seat situation, or a room that is acoustically very well treated for first order reflections.)_ Also, you'll need to make sure each speaker couples well at the crossover from the seating possitions (basically at 80hz reigion, and associated).
If you miss any of this, you'll end up with lack luster results! Of course, each speaker should really have relatively flat/even freuquency response as well. (a good starting point in a small rectangular(closed in) room, is placing your seats(if you have 2) at the 1/3 positions, and placing the speakers at the 1/6 posstions in the front. Then rears depend on dipole or dirrect, etc.(1/6 for dirrect, 1/3 for dipoles for 5.1). Placing center channel slightly off center of room. Good luck, hope it helps...
Can you get great results from these speakers?...sure. You need to follow what I said about the setup. I speak from 20 years experience and 6 audio stores experience...not to mention hundreds of system setups.
Hope this helps
