The 50's are great, keep them out from the walls and you will love them. If you can, raise them about 50mm to get the tweeter and upper mid/bass driver closer to ear level, and then they really perform well. They have solid bottom end to about 45Hz, with usable extension to 35Hz. Of course, this will be largely determined by your listening room, your listening position and the position of the speakers, as will the upper end of the system.
