Hello everyone, this is my first post.

If i wanted to use a pair of the speakers listed below, which would be better for rear channel speakers? I guess, I am curious if rear speakers need extra bass response or will a set of 2 way speakers get the job done just as well.
I am not familiar with how the frequencies are divided in a 5.1 system, so if the bass signal isnt even being sent to the rear channels then the larger 3way speakers would be pointless. right?
I would prefer to use smaller speakers for the sake of saving space, but if having that little extra bit of bass is worth it, i don't mind getting larger speakers.
