Speakers sound too bright.

Hi folks, I'm a little confused here. 

OP states his speakers are Martin Logan 60xti. According to Google, these were inexpensive home theater speakers, now discontinued. They were not panels, but standard 3-way boxes with cone drivers, made in China it would appear. Is that correct?

Why is everyone skipping over this is a dipole 1 foot away from the wall behind them? I dont care how long you burn them in, what treatment you use, the cables, the preamp- NOTHING will fix that "dipole close to the wall behind them" problem.

@lonemountain  The ML speakers the OP has are not dipole, they’re box speakers. 

Try one of the Schiit EQ components....It may tame the speakers to your liking.
