I have come to the conclusion that any great speaker should allow just the music to come forth with as little resonance added from the enclosure as possible. The quieter the box the better the sound. This is why lots of people like planar speakers. It has not been until recently with new materials carbon fiber, poured plastics, constrained layers, metal cabinets has box speaker approach this quietness that stats have. Yes speakers still sound different because of driver integration, crossover settings, etc. It is an art and good listener needed to get the best. I would look at the least quietest boxes and then evaluate the sound of the speakers to see if they are to your liking. The best Jeff
