Hi, thank you for the warm welcome and the helpful information.
It is good to know that these speakers were partnered in various packages, that does reassure that they will produce a cohesive end result.
Thinking about it the AVR does have a room correction system so that should align the sound of the speakers even if they do differ slightly.
The dealer I’m talking to has specifically mentioned driver re-foaming so it sounds like he’s done the job properly.
