NEW ScanSpeak Illuminator Woofer

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.

Yes, but a spider is in no way constructed like a projection screen. Spiders play a key role in controlling movement at extreme excursions, and the spider for this design would have to be very strong and substantial given an Xmax of 16mm p-p. Keep in mind also that spiders are impregnated with resin which seals them even further. SEAS showed a full range driver with a new open-weave spider, but this was for a driver with an Xmax of only 4mm p-p.

I understand that there's real differences in physical properties between the material used for projection and spiders. My point was that an open area of 5% yielded 2dB attenuation at 15Khz with the clearpix2 material. Then consider spider thickness; Wavelengths up to 3Khz that a typical midbass driver of 5-6.5" would cover would not significantly 'see' the material.

In summary, I think its a non-issue.

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.

If I got ahold of some I'd display that pretty rear end through a Lexan panel and illuminate(!) it with a battery-powered LED. With some luck it might lend itself to an OB?
If we ride Madisound, maybe they could become the OEM.

HI

OEM have the possibility to castomized but I think that for diy the standard are sufficent !!
I hope beryllium for tw...are too small rispect 9900 -9800??

The sound quality of Scanspeak are out of discussion ,zaph and troels think the 15wrevelator are one of the best woofer ever made ,I have a pair and " move a lot air " for only 5.1/4 size ,this new one do more!!

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.

we can always dream

p.s. - if SEAS can see fit to offer a new fullrange design to the DIY market (current rumored pricing between $800 - 1000 each?), with more or less conventional construction techniques, then why not dream big?

Yeah, if there is money in it, then maybe a full-range SS is not out of the question. But my gut tells me (no Colbert jokes please) that Tymphany wouldn't use SS for that, rather Vifa or Peerless?

If Tymphany could make something with this technology that sounded as good as a Fostex, etc., and were affordable, I wonder how much the name on the label would matter?

Vifa/Tymphany are already doing fullrange drivers:
