Cone Vs Dome

larbec7

I am looking at two different speakers and I am not sure what the difference is besides a whole lot of money. One has the Cone design and the other Dome. What is the difference? I will post the ones I am looking at and if someone can tell me which is best I would appreciate it. This is for my Home Theater system.

One is Home Theater and the other says 5.1 Home Theater. The top numbers are one style and the numbers under them is the other style. I hope this is not confusing.

The model numbers are Model #: PLK RM6750BK and Model #: PLK RM6880BK
