Thanks everyone!

 I went through a myriad of electronics and it was the speakers that were simply cohesive
This sentence should read, (speakers that were simply not cohesive)
If you don’t have room treatment, I would leave everything and solve that.  It’s to the point now where they aren’t obtrusive and can be made to look like pieces of art or any picture you want.  Then add a DEQX.
