Speakers sound too bright.

@tksteingraber 

Agree about the Dueland DCA 10ga.They tamped down my Cornwall 4's without loss of detail, and they had been thoroughly broken in by being in the loop of an old telephone transfer station for decades.

Also affixed one inch diameter punched out pieces of black gorilla tape one each to the "mouths" of the the midrange horns.

The nails on a chalkboard sound. Once one hears it, it’s near impossible to unhear.

It may seem like a crazy question, but how long is your speaker cable? 

These speakers have a rising top end from 7k up when pointed at your ears. Pointed straight ahead, though, they measure much flatter. If they still sound too aggressive pointed straight ahead, you might check out something like Dynaudio Evoke 30s or Emit 30s, which I'm betting would be more balanced and less fatiguing. 

I’m using the metal jumpers that came with the speakers. My speaker cables are 8ft.

i’ll try positioning them straight. 
 

They do have better dispersion and soundstage than my KEFs. It’s just the harshness than I’m struggling with. Maybe they just need to be broken in. 🤷🏻‍♂️
