Sonus Faber uses a silk elastic string something like this

There might be something to that, as the cat wouldn't be able to get to the drivers...
Even if it's easy to bend etc, the drivers would be save. Cheap enough to replace in
case of possible damage...
I can't make up my mind though, cord or elastic...
I could create the ends with a piece of angle steel...

one continuous length woven up and down with a tensioner hidden in the top or bottom plate
imagine guitar string like tensioner knobs up top for each strand?

That's what I've been thinking. I can hide the tensioner on top. Using an L shaped bar on top and bottom stuck between the current alu baffles.
With a printed guide on top/bottom to make it smooth resembling what Gryphon did...
So one long cord and a tensioner on top...

Do you think moisture had anything to do with the corrosion on the existing tc9s that led to their failure? Maybe a bag of desiccant in each chamber wouldn't hurt?In other news, about two weeks ago we had some storms out here. Due to that bad weather even my garage was flooded with water.
It wasn't much, but enough to cause us a head-ache. It made me re-think when to do the surgery on my arrays. The garage definitely
is a damp environment so I think it's best to operate during dry and sonny weather. If I don't, the damping materials might soak up enough
moisture that can't go anywhere after closing the speakers. Possibly creating future issues I don't want.
It probably means I'll have to be patent once more, as the Dutch weather isn't that reliable or predictable. But with any luck...
Why don't you just close the door to the music room? Does the cat require access to every room in the house?Still don't know what to do about driver protection...
The arrays were in the garage for almost one year, so yes... But the flooding I had a few weeks ago was the first ever in the 20 years we live here...Do you think moisture had anything to do with the corrosion on the existing tc9s that led to their failure? Maybe a bag of desiccant in each chamber wouldn't hurt?
It's my living room, I don't have the luxury of having a listening room.Why don't you just close the door to the music room? Does the cat require access to every room in the house?
I've been reading a thread on ASR with some interest, but it got a whole lot better when Sean Olive joined the discussion:
https://www.audiosciencereview.com/...r-preference-score.31454/page-34#post-1118050
Some interesting stuff is mentioned there, about the Harman score and it's validity.
I still think we, as DIY aficionado's can get the upper end of it by viewing our room and speakers as a system.
Some interesting points were made about testing in mono and it's validity for use in stereo etc. in general it
is good to see this subject being discussed so openly.

It sure is... I'm so glad I can make up my own mind of what to like. Still strongly based on (all) the research out there,
not forgetting what trends have passed in recording studio's etc. Like the LEDE concept, and the Haas kicker.
This, combined with research Griesinger presented has proven to come closest to MyFi. Or My kind of Fi. 😉

Completely agree.
Sometimes, people are so bent into posting about the preferences of this or that audio guru, they forget to listen for themselves and say what they really like for their ears (and soul).

It is done to add just a touch of credible envelopment, not to distract. In fact, if the upmixing is obvious, it is probably excessive. I have entertained stereo purists who did not know an upmixer was engaged until I turned it off, and the sound field shrank to the front. I await the perfect upmixer; the original Lexicon Logic 7 was excellent, but it is history. Auro3D is filling in and fortunately it is adjustable.
I guess I'm not that delusional with my ambience addition after all...
Floyd Toole said:The combined direct sounds from L and R loudspeakers acoustically interfere at the ears to generate an octave wide cancellation dip around 2 kHz for the listener in the sweet spot – an audible timbral error that is a permanent feature of stereo
The problem is that it is due to destructive acoustical interference - not exactly correctable with EQ. Besides, it audibly changes with tiny changes in position each side of the sweet spot. One can play mono pink noise and find the sweet spot exactly by listening for the amount of dullness. The more dominant the direct sound the more obvious is the effect. So, close-up listening or attenuated reflections make the problem worse.
Yup, that's what I've been saying for quite a while. And looking for ways to soften that problem without using (very) early reflections...
I'm still of the opinion that a little mid/side EQ can fix tonal balance as perceived across the stage.
Jury is still out on several cross talk cancellation tricks though, at least for music. I seem to like it for movies.
Even the Haas kicker (ambience addition) helps cover up the dip at ~2K, assisting/helping out the mid/side EQ.
Any dips further up in frequency benefit from (increasingly functional) head shading.
Cool to see Toole write so openly about it, probably as a companion text for him liking/defending the early reflections in a 'live room' (and caring less about imaging, as a classical music aficionado).
As he said: the root Stereo problem becomes more noticeable with attenuated reflections. But I've come to like the imaging within popular music, as long as it goes hand in hand
with tonality. Tonality comes first, but having it all is something else entirely! By 'all' I mean tonality, dynamics, imaging and envelopment. That's the combination I strive for.
Floyd Toole said:I can add that because of the double-mono soundstage and the consequent acoustical interference at each ear any thoughts of phase integrity in the direct or any other sounds arriving at the ears are off the table.
But it helps to have minimum phase behavior trough this problem area and use phase linear mid/side EQ.

I'm a bit late to the party, but I am just learning about spatial audio, from the likes of Apple and such...
As up now, it is only for headphones, but it might be applied to speakers one day.

There may be some action soon. The outside temps are pretty good and I suspect I'll have some free time to finally replace the drivers.
I'm in no hurry though, but I do look forward to getting this done. I will forego the driver protection for now. Our cat did not show her interest
anymore and hopefully it will stay with the two prior attempts (one jump at each array, showing very slight damage on two drivers).
She never seemed to have an interest, so I'm still surprised by her sudden attempts.
I'll type something new when I start swapping the drivers... I've been without the arrays for quite some time, as another driver failed leaving
me with crooked Stereo... (not fun...)

What about a thin wooden frame covered in traditional stretchy grill cloth. The frame would be held in place with magnets. The moment the cat hits the cloth, the whole frame detaches and saves the speaker. Very traditional type of grill. You could make them in 5 sections of 5. It’s more manageable and can be made saw or router and template. I did this on my 2 ways:
Just got back from my yearly concert celebrating the music of Led Zeppelin by the band Physical Graffiti.
They tour the whole of Europe yearly, except for those last two years obviously. If they are ever at a place near
you, go see them! The band is awesome but some of you may remember the singer, Andrew Elt from his days
of fame with Sleeze Beez...
Makes me very aware that I need to hurry up and fix my arrays! How I've missed this life of going to concerts etc....
More to come this year, Yeah!

nice to see that the world is starting to wake up again... it's been a little boring, for sure.
To many more concerts!

First step of the "big operation" completed... I moved the first (broken) array into the garage...
Baby steps. As it's the following day after a concert with a few to many beers, this feels like a great accomplishment 😀.
