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.

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:

thanks Joe - even though we may complain about finding exactly what (we think) we want, there are still too many choices to sift through

Hi All,

Check this pdf file!!

The last couple of paragraphs of the second page of the flier are particularly interesting:


The Illuminator series has been designed to offer the customer flexibility in sound and cosmetics. For example, raw frames are stocked with unfinished mounting flanges. The drivers are finished, including custom mounting hole patterns, paint colors, etc. according to the customer's preference when the order is placed. The flex frame option allows the customer to get what they want without long lead times or exorbitant tooling costs - even small orders can be customized!

Additional flexibility will be offered with multiple cone choices, including aluminum, wood fiber, fiber glass, woven Kevlar and carbon fiber paper. The standard offering will feature a paper diaphragm made from a proprietary pulp that incorporates a patent pending non-axisymmetric rib reinforcement pattern that reduces resonances to yield uncompromised clarity.

sounds like a diy group buy dream - depending on what constitutes a "small order"

nicoch,

Xmax and generaly all the T/S parameters seem to be amazing!
I'd like to have a pair in my hand , but I'm waiting for the prices too...

The other question is : Will custom versions be available for DIY/detail market? I think not but we'll see...

re Q#2 - that's where distributors like Madisound could well have more leverage than any group of diy'ers.

Of course, like with the new SEAS full-range, until final hobbyist pricing is announced, it's all pipe-dreaming.

Illuminator 6.5"

Really I dont get it...Fs 37hz...linear Xmax 16mm pp

I fore sure wont listen to a midrange driver moving like that

They sure know how to make a driver but have no clew how a speaker works:bawling:

There might be some folks who'd dispute that assertion.

These are classified as mid-woofers: I'd imagine many systems would be incorporating powered sub/ woofers, with XO point/slopes per designer's personal goals, but presumably avoiding over-excursion.

More importantly I think - have any of these drivers yet been demonstrated in "real world" enclosures?
