Corelli... That's why, outside of their phenomenal sound quality, I suggest looking at the Moab or at least the Double Impact from Tekton. Neither needs a Sub, at all, shipping is free and more often than not, there is no sales tax added,
On a $4K pair of speakers, taxes will be $280 to $400, and shipping of anything of any size with drivers to meet their bass requirements is going to be $600-$800 in addition to that at this point. In short, a good $4K pair of speakers with tax and shipping is going to be between $4,800 and $5,200
So the Moab at $4730 or even the Double Impact at $3,150 is a great deal. There are also (7) standard colors to choose from as well as making it a custom color for an additional $45 (obviously more if you want an exotic finish which they are happy to do). Just some food for thought.
