speakers for listener with Tinnitus

a tone control marked "treble."

I agree with Mechans on the cloth tweeters .
Also tubed electronics may help .
This is what works for me .

"Vandersteens, Harbeths etc.. might be the direction to head for."

Vandersteen's are very revealing overall and they use aluminium tweeters. I don't think they would be a good choice, in this case.

Here's a few speakers that have a very forgiving top end: Origional Mirage M series, Meadowlark, Mission, Older model Energy's that use the camel hair tweeter, possibly Martin Logan, Spendor.

If I can think of more, I'll post them.

I also suffer from tinnitus on and off. Despite this my hearing is still pretty good. A speaker system I found easy on the ears is Sonus Faber. Most any of their speakers lack HF fatigue so as not to aggravate tinnitus. If you're like me, headphones are a no-no at any volume above a whisper. Just do a little home work and you can enjoy this great hobby of ours as well as anyone else. Good luck.
