Larrybou, did you indicate how large your room is?
I found ls50s lacking in a larger room but quite sufficient in a smaller 12X12 sunroom with vaulted ceiling.
If low end authority and extension is the issue, adding a sub or two will address that.
Generally, you need larger speakers with more or larger drivers for larger rooms. Yes, good ones will cost more. It cost more to fill a larger room with quality full range sound. Adding subs also provides flexibility in placement of subs versus main in order to maximize everything together. Larger speakers often need placement closer to walls in order to deliver bass in larger rooms. Close placement to walls usually works against soundstage, imaging and detail, so getting an ideal setup for everything can be a challenge with most any full range speakers versus monitors + sub(s).
