You could always wait for a better price on the 7ii or try and get a set of b stock, or even wait and get used. I’m sure they would sound ok together (83 and 64ii) but the horns are different. It’s the horn from the old rf-64. At this point get what you want the front speakers are your main speakers if there’s ever a reason to spend more to get what you want it would be on the mains. They call them mains for a reason.[]
