I'm not sure why the IN-8s are not using any of that foam to begin with, it's a common sight in much more modest gear like soundbars or the JBL 104s.

There is! Just not on those particular cables to the midrange.

I would rather Dacron or polyester fibrefill in the cabinet. There is only light foam on the walls.

Rub/fuzz is not an uncommon problem and usually manifests as high order distortion. I’m talking 5th, 6th, 7th harmonics, 9th harmonics. They are totally unrelated to the musical signal.

The thing is, they are easily audible to the human ear. You don’t need a Klippel, but you need to know what to see if you’re measuring your speaker (usually with ear muffs on- who can bear that brrrrrrzzzzzup after the n-th time?)

And one must not lump all higher order distortion together.

Reference:
What can happen when a driver is “fixed” to the baffle without a vibration absorbing gasket:

It doesn’t occur to all samples.

I wonder whether they were products purchased locally? I bought mine before they were available locally. So it had come all the way from Germany to Australia.
Do you think 160hz seems a little low for an undamped woofer/baffle interface issue?

Its a resonance of some kind; port perhaps. Internal standing waves perhaps. It’s not the woofer because they are pistonic in that range,

I haven’t investigated further, maybe one fine day…

Wouldn't port resonance be much higher in frequency in this size box/tuning? Internal standing waves or some panel resonance? Would be nice if there were an easy diy fix.

This is such a worried-well-world.

The problem is really overblown.

Thin vibrating cables inside a speaker cabinet may or may not be an audible problem, because there are a ton of things in your room that vibrate ALL the time.

And guess what happens when things in our room go brrr, bzzz or boom?

“Look what my speaker did?!
That’s just Awesome!!!”

The problem is really

serious design fault can be overlooked and blow in the wind like nothing

let's say the final word: why bother,
there're many $5 earbuds with great deisgn

Your comparison to packed-in or $5 earbuds doesn’t make sense to me.

This is a speaker. And well designed one at that.

Have you got a IN8 V2 speaker okok?

Well I do.

Did you see the time stamp?

I bought this myself, with my own money, for my own personal use (home gym) in June 2022.

And was blown away a how Kali were able to sell such a great speaker for such a low retail price.
@KaliAudio_Official

So I deconstructed it in an attempt to see if I can finally put away my tools, give away that work bench, and rest my arms and back, not bother with DIY.

That was the the goal. Is it better than what I can build (for US$300). And the answer is an emphatic YES!

No other agenda.
I felt no need to post measurements or do a review of it.

I listened to mine.
I measured it.
And Listened some more.
No problems whatsoever.
I don’t have that “200-400Hz HOHD issue”

I thought I had a narrow band resonance issue, but having listened it for hours both soft and loud, its not audible.

Taking measurements is hard, interpreting them is even harder. The thing about the Klippel MFS is that it’s a heartbreaker- because it sees everything is ULTRA-HIGH resolution.

Is it a problem, or are you going looking for a problem.

When you buy a new car.
Whats the first thing you do? drive it?
Or do you take it to your mechanic and ask him/her to put it on the dyno, blast it, then take it apart and point out all its little issues, and critique at how well it’s been put together, it’s looks, it’s value, or how it could be done better, or differently?

Of course no one does the latter, but if you did,
I guarantee you that if you looked under a microscope, every car that comes off the production line has a problem.

Nothing is 100% perfect. But does it matter? Because as long as it does its job, then that’s then that’s fine.
When and if minor issues manifest in a problem that’s when you should take it up with your vendor and seek advice/assistance.

So whatever was the concern from the speaker- it wasn’t there until Nuyes pointed it out, and from there forward the owner couldn’t un-see or un-hear it.

Isn’t it unfair to be making generalisations as being a manufacturing problem when you’ve tested only 2 samples?

It is deserving of:
“Oh lord!”
“Serious design fault”?

Get real.
IMHO it’s making a mountain out of a molehill.


@Zvu Don’t ever invite a a builder into your house, and ask him to point out all the defects and flaws, before you even noticed them. And you’ll never sleep again.

Just giving a bit of perspective on this “issue”

These are from owners who purchased the Kali audio's latest product (IN-5) .

It is wired and foam processed.
Kali audio is a great manufacturer.
They recognized the problem, improved the product, and are manufacturers who can communicate with consumers quickly and correctly.
This is ideal, and I think many manufacturers should follow suit.
