Thank you to FrzinVT and Absolve2525 for helping identify...
Once i was on site, I better understood what was going on. EV t350 Added on to D model. The speakers have not been played for 30 plus years
I am thinking at this point I would restore and then I will sell them.
The pictures show the OHM readings of each speaker, on the 200 scale. I think they are within specs...
Thinking I will remove the EV T350s and sell separately. I see eBay folks are selling used ones that look like new, as in my case, for more than $400 each. Uglier ones for less.
I would have to replace the board that receives the horns, because of the gaping hole left by removing the EVs.
At the same place, I misunderstood about the middle speaker. I was expecting a Heresy and found a Cornwall
What would you do or recommend?
