My genetic drifts made it apparent that I might have to shoot my neighbor myself. (he graduated from the same faculty right before I enlisted).
Then I discovered that he's a serious alcoholic.
Pff, close call.
(maybe I can shoot the neighbor on the left instead, he looks too healthy for my taste)

Squeeze play
Purchased a pair of monopole AMT tweeters, and am awaiting delivery.
Having read so much about the improvements brought with this tech over other tweeters, as well as slot loaded, opposed bass drivers, I have to wonder- is this concept no good for the vocal region?
If it works above and below the midrange, has anyone tried it from, say, 200 hz to 2500 hz?

Some people are gullible.
Some are just plain stupid.
Some have no concepts of basic science.
Some do not understand failure to disprove is not proof.
Some people really do believe in magic.
Some people have thin skin.
Some people have no morals in business. Manufacturer, advertiser, publisher and the retail sales.
For some reason, blatant fraud and false advertising laws do not seem to be enforced in audio. Where in the past, they have shut down patent medicine which at one time claimed to contain snake oil. ( for those non-US history international folks)
Conclusion? Creativity is alive and well and there is enough stupidity around to make it profitable.
There seems to be a resurgence of AMT's. Materials are better for sure. The ones I have heard ( ML and GE) seem OK at quick listen. They may have some advantages, but share many other problems with ribbons due to the packaging. Diffraction control for example. How wonderful it would be if we could actually get a viable 1K up driver. Keep us posted. Maybe the multi-way forum would get wider feedback.
there's also innumeracy - some which should be dealt with in public education - but there are specialist engineering/scientific points you can't expect the general public to know
some ad copy relies on "puffery" and misdirection - possibly "true" theories/effects (a very few of the mentions of "quantum" in audio products) or measurements - which when put in full context have negligible effects - below thermal noise, Brownian motion randomness of the air molecules hitting our eardrums

The one and only full range AMT
Is the title of a thread by RayCtech.
Coolest article I've ever seen here!
Seems completely awesome if you wish to look it up.

I'm not ready for $600 tweeters. That is why I have not tried a ribbon yet. It seems that is about the minimum anti to do as well as a $100 dome.
My question is dollar for dollar, which is the better overall tweeter? Is the AMT cost justifying a step above what other technologies can do? Are $5 (OEM cost) AMT's better than $5 OEM cost domes? The gentleman behind Golden Ear is no rookie with regard to price/performance so I doubt he would have picked AMT's as a gimmick.
This much, at least, is absolutely true: Every cable can be characterized for its electrical parameters. Resistance, inductance, and capacitance can all be measured.
Since any cable has these characteristics, it is definable as an RLC network.
Since it is an RLC network, its response modification to the signal passing through it can be calculated with precision.
I do not question for an instant that cables having different RLC values CAN make an audible difference in the sound you hear.
What I question is the real cost and value of one cable vs. another.
Short of those cables made of exotic materials and/or precious metals, I can't imagine any cable that costs more than maybe 10 dollars a foot to make. And even that is a generous allowance.
The idea of directional cables is absolute BS. Totally unsupportable via any valid application of electronics and electromagnetics theories.
The idea of charging hundreds of dollars per meter for cables is absolute genius, if you can get suckers to buy into it. But the cable being sold for 500 dollars for a one meter pair represent a cost to manufacture of maybe 50 dollars tops, if the manufacturer is buying the connectors at full retail price.

Read the thread. Wonderful claims. No product ever put into production, so not really helpful.
There is also th snob appeal factor. True story a Caly turntable maker in the 80s changed distributor in the UK and reintroduced the products for 3 times the old price and unit sales increased by a factor of 3 ! Answer was it now sold at a price that keep the lower classes from owning them . This is a large factor added to the very low amount of product sold in the over priced cable market .
For some it never ends. A good friend bought some very expensive MIT cables, loved the sound of his system so much he declared it finished.
Then he came over and listened to my system with its absurd 22 gauge twisted pair solid copper cables used throughout, and the 30 to 40 year old Seas/ Peerless paper drivers, and said he was hearing things he didn't know we're on familiar songs.
Did he change his mind about his speakers or anything else likely to account for this?
Nope.
He's decided to try even more expensive equalized, sorry, networked ,cabling.
?!
Twisted pair 22ga makes pretty good connecting cable. Multiple 22ga wires make a pretty good speaker cable. This is known.
It would be pretty easy to make a directional cable. Put a significant series resistance in it, and a lowish shunt resistance between + and - at only one end. The power amp will drive the the shunt resistance if it is connected to the shunted end (at least till the amp runs out of current), but if you turn the cable around so the speaker (higher impedance device than the amplifier) is on the shunted end, the setup will play much lower than with the other way around. Various ways to mix inductors and capacitors into the mix to get similar "directionality". All of which are dumb things to do on a speaker cable, but, hey this is audio,
And with all the money we save, we can buy a lot more music! For me, it's all about enjoying music. I gave up worrying about bragging rights about 40 years ago.
For the cost of one "magic" cable, one can buy enough Owens Corning board and burlap to do seriously effective sound treatment and REALLY improve imaging. For the price of the next "magic" cable, we can buy 5 roles of insulation, wrap them up in a corner and have a real bass trap. Actually, maybe the best investment is a copy of Floyd Toole's book.
Even easier
Could one not just use a thicker gauge conductor on either hot or ground cabling to establish "directionality"?
I did , but couldn't hear any difference.
But then, I did this at the paid request of an audiophile, and said he could hear it clearly.
He is about 20 years younger than me, so maybe he's hearing things I no longer can.
This was simply 3 22gauge wires for ground, 2 22gauge wires for hot, all twisted with a hand drill , and gussied up with cable pants, shrink wrap,and tech flex .

I found this website which generates a webpage suitable for those who sell super expensive audio solutions Click the button at the top and see various options so you can differentiate yourself from the competition.
It won't let me post it because it won't allow the BS word. Clicki on the link and replace the stars with the BS word (lowercase).
You see where this is going, right!

Once I figured out the link problem (the page title is asterisked out by our forum filter), I was delighted. Thanks for finding this.
I think I'm ready to keep up with KBK!
