I am still using my Arphi super challenger speakers (in front) in my HT setup with Yamaha RX V671 and they still sound amazing. I bough them in Mumbai (then Bombay) in 1992. Nothing has been changed/replaced/modified with these speakers.
Ask the seller to share pics of the speakers without the grills on.......I am sure most of us who have used Arphi will be able to spot if they look reconed or not. Share those pics here...
