more drivers equate to better sound?

[STARSCREAM]

Backstory is that I had the Polk audio VM30's which had lots of different drivers and I loved the imaging to them. Now I recently have the Polk audio Rti a5's and just don't like the sound right now. The imaging is less and I'm just not getting any dynamics it seems. Got me wondering if it's because they have far less drivers than the VM30's and if this is necessarily the case all the time? I had always heard that the bigger the speaker the more air and room it had to move and give off bigger soundstage but thus far that is not the case for me.

EDIT: I think I've fixed some of it now. The imaging still isn't as sharp as the VM30's were. On my new Onkyo 608 I just got I had Audyssey dynamic eq turned on which greatly enhances the surrounds volume and this was causing the surrounds to drown out the fronts. After also turning on Audyssey dynamic volume the rti a5's have come alive and the csi a6 center is very clear on dialogue. Much better. I went back and forth messing with all settings on the receiver and the most dynamic setting for sure was having dynamic eq on along with dynamic volume turned on and set to low.
