Thanks Scotty and Elizabeth. I've got it for the 3.6s. But the 1.7s were also shipped with a metal strip (~ 2/3 the tweeter, panel radiating surface, length) and there is no obvious place to put this, though I have, on second attempt, found that it does adhere magnetically over the tweeter domain, but where exactly to place it. All of the way on the far side the speaker, but that's just over a part of the tweeter region?? There is no slot as on the the 3.6...
