I predict the old codgers at Stereophile are going to lap this speaker up.

Just like a kitten to milk. LOL

Then why is Focal using Beryllium for years?

And why did they use titanium before that? It's all about selling loudspeakers. You have to convince the purchaser that the tech has moved forward otherwise they've no incentive to upgrade their old titanium dome Focal to the new Focal.

That they used an inverted dome is what actually matters to the sound pattern of the speaker.

And is it any better than a traditional dome?
It does seem opposite a "common sense" approach to a broad radiation pattern?

beryllium is good - but there’s very little in it compared to other drivers with the same design, so it’s more glam material/ marketing hype than going to make a big difference
Here’s measurements of four tweeters of otherwise/ essentially the same design
Be did better than two others, but not by a margin to get excited about

BlieSMa T25A-6, T25B-6, T25D-6, T25S-6 | HiFiCompass

What is on the test bench? At the annual Munich HighEnd-2019 show the founder and designer of BlieSMa company Stanislav Malikov аnounced three new tweeter models - domed T25A-6, T25B-6 and T25D-6 which have 25-mm membranes of aluminium-magnesium, beryllium and CVD diamond respectively. At the...

And both is still on the market today

Lots of products are - from some manufacturers. Longevity ain’t the best metric for SQ/ $

Blah! Andrew Jones again. Mention his name, and silly little audiophiles wet their pants...
If the guy is so good, why is he always changing jobs? You would think a company would give him a fat contract for a long duration, if he were the God of speaker design many claim he is.

2 Giant magnet structures with 10" cones, 15" equivalent, gap management for long excursion, 160 lb unit and you get down to only 34Hz?

A port tuning of ~34hz is actually around where ported enclosures are typically perceived as full range in practice.

It's his own company, he doesn't need a contract anymore

There were a few hard tail mountain bike frame-sets built by a company in the mid 90’s out of a beryllium alloy composition but I can’t remember by who?, I do remember they cost many thousands of pounds £££££ back then so I imagine they were “promotional” in nature

 

[Frank Dernie]

Beryllium-Aluminium composite was banned from Formula 1 since it was too expensive.
Mainly used in engine blocks to improve stiffness at low weight it gave a marked improvement in power due to the stiffness.

So AJ sees big money in the class A amp market, I guess?

Many of his speakers in many different companies and price points have measured well and gotten great reviews. As veteran of many startups in R&D, I have worked with many talented engineers that find once the the design is going to production with new challenges that require less invention and creation they lose interest. On the other side those charged with high output and lower cost can find those individuals hard to work with because of the compromises they need to make in a design. I have no understanding of Jone's personality and work style but he seems affable in his videos.

Regarding the field coil, this seems like a case of "just because you can do something...". Would love to know if he actually tested a conventional approach as well and the field coil was *actually* better in some way he preferred. Or is this just "I felt like doing something different just for the sake of it and will have to figure out marketing bs to justify it".

 

[Pearljam5000]

Transient accuracy?

 

[MattHooper]

I would have thought it obvious that the loudness achievable over the frequency range will be much greater with bigger more efficient drivers. Whether you need that is a different thing.
Possibly with less distortion too?

Yes, that was the obvious inference, which is why I was wondering if it goes beyond that… whether there would be significant differences in the presentation between two such speakers playing at the same volume and if so, what?

For instance I wonder if the AJ speakers wouldn’t require as much volume in order to sound satisfying or dynamically alive or whatever.

Audiophiles are attracted to unique selling points independently if that is sensible or not like a moth to a flame and that is usually a well working approach in that market.

 

[mhardy6647]

Perhaps the Troubadour SE will step up to a plasma tweeter.
a la the DuKane/Electrovoice (etc.) "Ionovac" of yore.

https://products.electrovoice.com/binary/T-3500%20Ionovac%20EDS.pdf

... although, come to think of it, a coaxial plasma tweeter might represent a particular engineering challenge.
I guess it's a good reason to consider a Kevlar cone. Or maybe Nomex.

That is common audiophile misconception like that for example light membranes correspond more linearly at lower volumes or first tube amp is more dynamic but in the end it is physical laws like Newton's second and linearity measurements of very different tsp parameter drivers never showed such deviations, so it's like for most audio stuff mainly the frequency response tuning plus some parts placebo/expectation due to not doing controlled testing. As in the video the target buyers are low wattage tube owners which have usually also too low output impedance outputs which change the frequency response on every loudspeaker differently due to the different impedance curves so they can play all day randomly combining loudspeakers and amps.

Look at his foot - it's all the way in front of the speaker. And his upper body seems to be behind the speaker. While speaker seems to be at pretty deep. Don't think it is just keystone effect - but have been proven wrong many times before...

Just looks like the effect of a wide angle lens to me.

 

[WillBrink]

Details on field coil design. Seems to me it's quasi active design. Is it for added cool factor or something measurable as to benefits? I don't know, above my pay grade. It appears they are really targeting the low watt analog older "vintage" crowed. Almost makes me wanna try tubes

Looks wise, 10/10 for me. If they sound as good as they look, and they are a good value for $ as his other designs have been, sign me up! They scream "end game speaker" to me, unless they are priced into silly land. Do we know the expected MSRP?
