Grainy sound in the highs drivers on voice only

[Lucifer1to10]

i tried moving the driver on another horn i had around the house, bigger in size same result ,its a grainy sound in the vocals like right behind the vocals like a shadow or a a countour around vocals

What crossover do you have? Do you specifically compensate the CD/horn curve?

winford wf-2a80-k2 crossover no i dont compensate the horn curve, everything was flat for the tests also if i try high cut or any other adjustments the eq is working ok but the grainy sound remains , just boilled and oppened one driver , i don t think it should look like this inside

i got a wiim pro ,conected the amp to it and no change ,so it is impossible for me to find the actual source of the problem , also tried another amp with other speakers, same sound '"grainy" " sandy'" only on voice also tested on headphone same thing ,even on Bluetooth i really can't find the problem ,from my testing it results it is not the amplifieres or the speakers being that on headphones i get the same sound , tested line out ,optical out , Bluetooth out and all the in options ethernet,bluetooth line in ,optical in ,played with all the settings in the wiim pro nothing removes that grainy-sandy sound , called a few friends over same reaction they all hear what i hear ,so i guess my hearing at least is fine , i cannot imagine what is going on if u guys have more ideeas let me know please !
