speakers for listener with Tinnitus

Guys, Impossible question to answer, everyone's tinnitus is different. One guy might ring at 3.5k and another guy ring at 7k... Intensity varies and occasionally multiple frequencies.
There is no catch all speaker to fix multiple listeners tinnitus issues.
Cure tinnitus

How do you cure Tinnitus ? I thought that it was incurable .

Saki70, That Statement is called sarcasm, it went hand in hand with my opening line "impossible question to answer".
Sorry for any confusion.

I don't have tinnitus so my knowledge is indirect, but would equalization with a selectable notch filter work? Find out where the ringing is frequency centered and apply a steep, narrow band filter.

There is no cure for tinnitus. Try googling tinnitus and Johns Hopkins or Mayo Clinic. Mechans is asking a question many other audiophiles should be asking themselves. Tinnitus can permanently worsen with repeated excessive exposure. My personal experience is that it is worse for a day or so if I listen at average 75 dB for an hour or two.
OSHA recommends no more than 2 hours exposure over 85dB daily, or permanently hearing loss may occur. Richard Vandersteen wisely warns listeners not to listen at high volumes.
Choosing a speaker that is detailed at low volumes is smart.
Many folks have posted that Harbeth is such a speaker, but is certainly not the only choice. My experience in this regard has been extremely positive with Harbeth, and I have two pairs. Harbeths are sometimes criticized for not being designed to handle 100dB or more, which is find disturbing as those sound pressure levels repeatedly and sustained inevitably damage the hair cells causing hearing loss.
