spathak94506,
I have the complete opposite experience with the 7.2. I never heard them described as lean. Mine produce check thumping bass. There are certain things I only play with them as evert other fails in bottom end compared to the 7.2.
I have a fairly large room 37'x60' with 10' ceilings which allows the 7.2 to clear its throat and open up and sing.
The 2.4 is a gem of a speaker.
