You are welcome my unicorn compatriot! 😉
I would not say all french but most french are! Lol.
No more seriously i think it is just a language shortcut from 5th elements, that is all. And it comes to preferences which are difficult to argue against. His point about size is relevant.
Then if you don't have size limitation about box: why bother with low efficiency small drivers?
;D

Can really agree about tending to box issues.
But untreated enclosures, simply has nothing to do with a particular sound imo.
What do you mean by "PA sound" ?
I'll guess you mean what is often called 'music industry' boxes, not major touring or higher end install.
My experience is that boxes from PA companies like Meyer, D&B, L'Acoustics, Martin...just to name some majors ...and even better boxes from Yamaha and more everyday brands, are very well constructed and treated. Very well.
Often in ways that make much more sense and give bang for the buck, as opposed to what are often questionable home audio industry techniques.
And PA can be very hi-fi imo, in fact more hi-fi than traditional "hi-fi" 😉
I say this from the perspective of a guy who still keeps full range electrostats running for comparison's sake...along with synergies, line arrays, and many other proofs i'm a fellow Audioholic 🙂
just my experience /2 cents
I wasnt passing any judgment, really 😉
PA sound = playing loud.
Playing loud which means we're not paying that much attention to details...
Rock concert or in a club, I really don't think those are places where ''HiFi'' is the main goal, to say the least.
I think the goal is loudness and perceived loudness (bass).
I fully agree with you, Mark.
I really do enjoy using PA components for HiFi projects, in fact.
I really don't care what are the components ''made for'', or to which market they were designed. Specs is what is really important, that's it.
For years now I use PA components, ''real'' Hifi components and Car audio components for my projects.
not to mention the most important question:
Is said distortion objectively audible. If yes, to what extent?

This has interesting driver on top. Up to 694hz

I think I might go for the Faital 12PR320.
Still decent extension, but doesn't require a nutty huge box.
Allows me to try a 2 way with cd, or 3 way with cd or dome.
Tony from Humble Homemade Hifi really seems to like it.

Well - ten pages of intense discussions and you decide to use a whimpy 12" without shorting rings ?!? 😉
Fun aside:
The shorting ring story depends heavily on the ampount of inductance also and how it is changing in relation to excursion. The problem with the inductance is that it causes signal-dependant impedance and therefore intermodulation distortion because low frequencies can modulate the higher frequency components in amplitude and phase.
By how much does depend both on the driver behaviour and its use as well. There are pole-shapes (T-pole for instance) where less modulation of Lvc takes place. Less modulation does also take place when the magnet material is conducting and better able to saturate the pole material (a property of Alnico). It does also help if Lvc is not too high and/or the driver is not operated up to frequencies where Lvc plays a significant role while being used for very low frequencies at the same time. And not to forget: Less excursion means less modulation of Lvc. So if you use drivers that are well dimensioned for the task it is less of an issue.
And yes, that Faital is definitley one that I am also tempted to try.

I think this is definitely a nice woofer that only costs an arm OR a leg (and not both like a TAD).
The newer version is probably even nicer with TSPs a bit like a TAD.
I wonder how the new 18s Tetracoil (which is also some form of differential drive) models compare to those JBLs.

At low power levels the power supply is going to have very little do with the amplifiers capabilities. Unless it's been very poorly designed/implemented and there's a ton of mains frequency hash spoiling things. In this respect the SMPSs in chord amplifiers have an advantage vs traditional transformer designs.
No not really. You can see something like the Purifi woofer, with it's insanely long voice coil, has class leading levels of intermodulation distortion. If there was any loss of control from such a thing it would show up there.
Realistically speaking adding in more voice coil layers and increasing the coil length increases the drivers overall inductance. As a generalisation you could say that doing so reduces the drivers effective bandwidth (rolls off the high frequencies) and such a driver should show increased harmonic distortion because of it but that's just a generalisation. With good motor design these issues are reduced and the drivers performance is maintained. It's all about the specific application and you'd need to have measurements to assess the drivers performance.
I agree with you. It's not 100% necessary for good driver performance. If you have third party measurements of a driver without shorting components, and it performs like a champ over the frequency range you want to use it for, then go for it. But if you're buying it blind and have the option to buy a very similar driver with shorting vs one without, pick the one with.
The words 'on the whole' stop it from being a blanket statement.
Definition from Collin's online.
You use on the whole to indicate that what you are saying is true in general but may not be true in every case, or that you are giving a general opinion or summary of something.
No argument with the first part but what is expensive?
Take Faital for example: 5FE100 and 5FE120.
Only difference is one has shorting rings, the other doesn't. Retail price difference about £1.30.
