A newbie to the Gallo acoustics speaker.
Well I was fraudulently  drawn into a purchase listing ID # lis9iied on Adiogon. Dated November  30th 2019.  Being a newbie to Gallo acoustics,I thought the photo on the cover ad was what I was purchasing. After the purchase I found the front drivers to be totally different than the manufacturer had put into production. Upon much research and correspondence with Stephen of Gallo acoustics, these were never manufactured by Gallo. It turns out to be a hodgepodge of drivers passed on as authentic. Now ,not being an electrical engineer, I have no way of knowing ( other than what Stephen at Gallo told me were the right drivers to purchase. I would love to get these classic speakers back to the original condition.  Please be aware and cautious on Audiogon and Ebay of thomas_mitchell.
Any insight would be greatly appreciated.
