Hopefully I'm not toooo late to this discussion! I recently got my grandparents' AR-1 and AR-2 speakers. I've been using AR-6s for years, and I was wondering: Can I mix the AR-1 and AR-2 with a basic 1990s Sony receiver (https://www.hifiengine.com/manual_library/sony/str-av720.shtml), if I remove the strap on the AR-1? Or can I just connect them as is, despite the 4 vs 8 Ohm difference. It seems the strap removal wasn't for matching impedance but am curious how I should approach this. Thanks!
