hello everyone ! i found a pair of obviously quite rare INKEL PRO -10 LOUDSPEAKERS in the trash by the road . they seem to be VERY well made so i googled them and found little or no information,specs ,and only one mention of a pair for sale from 2003 ,they look to be from the 70s , with a 10 inch bass driver and the weirdest 1.5 and 1.0 inch INVERTED dome tweeters! ,the tweeters have a badge on front with the letters FRS, in a neat 70s script, nice looking L pads for both tweeters, in front a gold badge saying ACOUSTICS INKEL
also a small switch by the l pads that indicate INCREASE and NORMAL, I never have seen or heard of these speakers, has anyone heard of these speakers or does anyone know the specs,? the tweeters are beyond strange! missing the two bass drivers but all else intact with a really nice looking crossover network and heavy wiring!i hope someone can help!
