As well as extra level, one has a larger open baffle so they go lower before dipole roll-off.
They give a very particular kind of sound.Very big. Diffuse. His other speakers are BC1 (that i sold him nearly 50 years ago), and the aforementioned Rogers LS3/5A.

It's a bit "philosophical" to address in this technological thread, but the reprogramming of human beings brain can happen in various ways, and basically the term "program" itself can mean different things.
Aside from the meaning, the interpretation of the term itself also derives from one's personal whole experiences, namely the what, when, how, where and why we did what we did and therefore we are what we are.
The context can also be different, where everyone chooses the path of "healing" (reprogramming) that they deem most appropriate.
That choice depends largely on what one knows or does not know and almost all the rest of what is not known, but whose "presence" he feels, pertains to the spiritual sphere (where "spiritual" does not pertain to "religion", but to a journey of the heart).
If the personal path is saturated with "materialism" that person will act and think in a materialistic manner, with everything that automatically follows from it, therefore sooner or later it also becomes a choice and it can no longer be said that one was created like this and he can't do anything about it.
Not to mention the extreme cases, which however cannot be talked about here.
Taking the first step, if you are able to take a first step, matters.
And you have to be able to accept the possibility that we've got it all wrong.
Because if you are tied and anchored to your preconceived ideas you will get related poor results on that journey.

I wanted to reply a long time ago, but I've been too busy.
Yes, treatment with psychedelic substances (here we talk about Psilocybin) often associated with psycho-therapy represents a huge step forward by Canadian Health institutions in order to be able to respect and exercise the human right to health without violating international laws on the use of psychotropic substances "normally" considered illegal.
Therapeutic indications are related to certain types of disorder.
IMO The demonstration of civility of Canadian institutions regarding the above is not only admirable, but has no precedent in History and obviously receives an instinctive than wrongful "rejection" from those who have been influenced by concepts that in reality do not belong to them, but that have been instilled in him by decades of misinformation.
The brain is highly neuro-plastic and I guess that the Psilocybin use is based also on that premise.
On the other hand, just to give an antipodean example of incivility compared to the huge Canadian emancipation, it's enough to think that there is a nation in UE, whose name I won't mention for the sake of peace, which has outlawed "cannabidiol" (which has no psychotropic action) of which not only do the legislators know nothing about, but they didn't even inform themselves before, nevertheless they legislated against it.
It seems like for them, the uncivilized legislators, it was simply enough that the name of the substance began with "cannab...".

The Schumann wave could addresses reprogramming of the subconscious or conscious, but difficult to be certain. But something‘s going on. I’ve been experimenting with a number of so called “healing waves,“ many of these binaural beats are streamed from YouTube on my iPad whilst listening on headphones. There are a lot of interesting frequencies available, Alpha, Theta, Schumann 7.83 Hz, Solfeggio frequencies, and others. It’s gonna be very hard to beat the Schumann frequency. On headphones the sound expands outside the earphones almost as if my head increased in size by a factor of five. Also more air, more dynamics. Who can explain it, wise men don’t try.
from Theta rhythm Wikipedia page,
“Theta waves generate the theta rhythm, a neural oscillation in the brain that underlies various aspects of cognition and behavior, including learning, memory, and spatial navigation in many animals.[1][2] It can be recorded using various electrophysiological methods, such as electroencephalogram (EEG), recorded either from inside the brain or from electrodes attached to the scalp.”

This concept came with the ESL63.
The ESL57 is more like a strip, lightly curved vertically, so the "point source" is far away at the back.
I've never been able to align a stacked pair of '57 properly because of this, and the vertical beaming: align along the curvature of the '57 makes the beams diverge, and aligning the beams to converge at the listening point makes the virtual source diverge.
Btw, you guys're done beating each other up? 🙂
Dipoles; the QUADs shouldn't be directing much energy towards the side bookshelves. The rear wall is reflective/absorptive and pseudo-random, the energy hitting the large glass doors appears directed to the same back wall. Barring bass nodes that actually looks pretty well chosen here. Jealous.

By accident, once the 3 walls of records (all jazz) are accounted for, is almost exactly golden ratio, but a sloped ceiling would help.

How come no complaints this picture is snake oil nonsense? Wrong thread for that?
All the more for this one:
Does that prove sound is hi-fi?
Maybe its that nostalgia trumps indignation and disgust?
My Mark you are being righteous. Aren't you the one who used to quote an ESS marketing slide deck to show noise floor modulation in DACs was audible because the manufacturer said they could hear it?
FWIW a quick check says that the first resonant mode of a wine glass is around 700Hz so yes I would expect a tape deck to be able to faithfully reproduce that and allow the shattering of a glass if you had enough SPL capability

Hi Bill,
It was a rhetorical question. We accept a lot of absurd advertising for all sorts of products. However, sometimes in audio forums there is a particular intolerance for the same type of 'dishonesty' when it comes to certain audio gear.
Regarding the glass breaking, of course its about hitting resonance. It doesn't take a certain brand of tape to do it, nor does it prove high fidelity. Therein lies the dishonesty. I'll bet they made more money selling tape than other people make selling $20,000 cables. The tape guys could afford to advertise on TV, the cable guys aren't in the same league at all.

comparing a $4 (or whatever they cost in the 80s) tape to a $20,000 cable is still extreme. Not like they are claiming their super metal tape in a gold plated case was the only one that could shatter glass.
@gpapag where did you get RPM from. Only mention of that I can see is a 10 turn pot in the text?

Bill, it's at the bottom of the page:
"The stroboscopic illumination should be adjusted so that it shines down at a 45° angle. The strobe is calibrated in RPM so the resonance frequency must be converted to these units--we usually multiply the resonance frequency by 30 and then fine tune the strobe to obtain the desired beating pattern."

Something of a difference. Many on this forum would call cassette tapes capable of high fidelity (whatever that is) and sound can break a glass. A tongue in cheek ad is not the same as pages of pseudo scientific screed as found on some websites, without a hint of humour. If the cable guys sold similar revenue levels then they could afford TV ads. However - their market is not as big as tapes were. I don't know anyone who spent $20000 on cassette tapes.

Such practices are not generally accepted. Many countries have agencies that supervise false or unfounded claims in advertising. Free speech is not the same as the freedom to ventilate outright lies.
