Default Attenuate highest highs?

I have a pair of 2-way speakers that I like very much - except they go too
high and are too bright. They're Sony SSK-30s and otherwise make great
near-field monitors in my office. They image and reproduce voice
exceptionally
well.

I'll be 60 next year and can't hear a huge amount above around 16 - 17 kHz.
However they distract me too much with sounds that I can barely hear (no
other
speakers that I've heard lately do this). Because of this they're tiring to
listen too. Sony sold them as being ideal for SACD and claim they go up to
70
kHz (and call them "Extended Definition" speakers).

So what can I add to the cross-over to attenuate the highest highs but leave
the main body of the upper frequencies at the same level? A tiny inductor?
Surely a resistor would drop all tweeter frequencies and mess with the
balance?

I have other speakers I could use but these just sound so damn good
otherwise.
Re-discovering music from my past through these is amazing, music I've been
listening to for decades has new stuff in it... (A cliche but very true in
this case.)

I tried using a pair of Goodmans Mezzo IIs (that I've always liked) for a
few
days but they are lacking in the very upper frequencies (likely due to the
32mm SEAS tweeter). I want the highs to be there but not in a piercing way.


That should have read 36mm (1 1/2") SEAS tweeter, the same H-087 Alnico magnet driver that was used
in the Dynaco A25 and A35 speakers.

Input appreciated.

**If your hearing is attenuated at HF, then you don't need to further attenuate HF (assuming the
speaker has been competently designed). You've already stated that you can't hear anything above 16
~ 17kHz. Perhaps you should consider room effects. Have you measured the in-room response?


The speakers HAVE been competently designed. Sony still sell these SS-K30EDs in Japan (albeit with
a 'piano black' finish rather than my vinyl-wrapped version) and they're still popular. Also I've
checked them to the best of my ability (I often open older speakers and rotate woofers 180 degrees
to combat sag in the suspension) and they seem to be in perfect condition.

My hearing is attenuated above about 16 - 17 kHz. However it's not a clean shut-off. More like a 6
db/octave slope. I have trouble hearing quiet test-tones but a lot of what I listen to seems to
have quite a bit of high energy high frequency content. As I can barely hear it it makes me strain
to do so, which is fatiguing. Also I keep checking if there's someone at the door or things going
on in the back yard etc.
