NEW ScanSpeak Illuminator Woofer

[jupiterjune]

"minimum quantity 100"

group buy!!!!!!

[nicoch58]

"minimum quantity 100" = 50pair!!!????

For now it only for tw ...group buy is possible !

BERYLLIUM is the last material ,focal utopia and usher sound fantastic

But we must look forward, a cooperative project , diyaudio project!!

Seems that the spider must be somewhat transparent audio wise - or partly transparent and diffuse, so the new basket and 'shaped' motor assembly will work as intended.

I note also the sort of clover shape/pattern. This would seem to replace the sliced paper to control breakup modes.

They look interesting - too bad you can't see what behind once it's mounted. I suppose it is not for looks but for sound.

Did they mention prices?

PS: The Tymphany website has gone back to use the Vifa name again - not going to use V-Line after all? There are also exotic coned version of Peerless HDS coming out - it all happening fast!

The big shift here is the motor structure which goes from overhung ferrite with a copper sleeve to underhung ring neo with copper rings. Each approach has technical advantages and drawbacks, but that shift also represents a huge increase in the cost of the magnet system. The open spokes are nice, but the spider ring diameter is very large, reflecting back a lot of energy from the rear of the cone. The basket design is interesting, but the double screw 3 point mounting system leaves way too much space between mounting screws, and overall it is rather deep. It will be interesting to see how these drivers are priced, especially with the Dollar crashing vs the Danish Krone.

If price is no objection, this is more good than bad... but I like deep boxes for good midrange performance. Any driver that covers the mids likes a large volume behind it - the bigger the more anechoic it becomes and less delayed energy coming back through the cones.

That is what struck me too. But the ribbing of the spider will diffuse somewhat and maybe the spider is designed to be more transparent? We don't know - it might be very open weave?

That I hadn't noticed. Sharp eyes. You will need some strong T-Nuts. Could the rationale be here that it causes less buckling forces when mounted this way?

very interesting indeed -

As far as mounting holes is concerned - the cast flange certainly seems thick enough that buckling wouldn't be much of an issue, but 6 spaced in a conventional 60degree pattern till seems intuitively to make more sense.

Re the spider - many of S-S previous designs, as well as numerous other makers have incorporated stacked ceramic magnet assemblies with approximately equivalent or even larger diameter "shadows" - which are in many cases closer to the rear of the cone than here. As implemented here, the spider has to be more acoustically transparent than as when usually suspended mere millimeters above the top plate of a far more massive motor assembly.

Aside from the "cost" of mounting depth everything about the open, trussed basket frame and gorgeous, almost sensuously curved motor housing makes sense.

If these new design features would be incorporated into a full range driver, along with some other changes that I'm sure the DIY community would love to describe ( reverse roll or funky Fostex Sigma type pleated, embossed or CNC painted EnABL style patterns, etc,) this could evolve into an entirely new paradigm of driver performance.

Ask yourself this - when manufacturers the likes of Feastrex, Lowther, PHY, Fertin, Supravox, AER, etc., can command their prices, how expensive is "too much"?

I'd guess that clover leaf pattern is an equivalent to the EnABL process.

Have you seen acoustically transparent projection material such as the clearpix2 from Screen Research? You can project an image into it with perfect clarity yet it attenuates sound by only 2dB at 15Khz! Also consider the thickness of the spider, its a fraction of a mm. This will allow the vast majority of sound to pass through without being reflected, only very short frequency wavelengths are to be considered troublesome and even then if its around 5-10%(equivalent to the clearpix2) open weave then not a problem.

Perfectly explains the shape of the upper poleplate, allthough there may be another reason too

Surely they look much better than previous models

I would think that given the existing ScanSpeak business model, the goal for these drivers is to be priced for usage by "small" OEM's like Wilson Audio, and delivered in lots of a few hundred at a time. And in the case of OEM's-even very high end ones- there is indeed such a thing as "too expensive". The names you mention certainly command extremely high prices, but I doubt the quantities they actually sell would be anywhere near sufficient for Tymphany.

And while nothing stands in the way of developing a full range driver based on this concept, I don't see anything in the present design that points in this direction.
