Is it a rebadged Vifa P17?

It's got a fiberglass cone instead of the P17's poly--I was thinking it might be the MG18 with the cone dyed black instead of the old yellow.

The P17 had an inverted surround also. But it is similar. Frame seems to be about the same. Looks a lot like P17RCD. They were great drivers.

the frame is similar to MG18 but spec is different and it have no hiccup in the response like MG18. It look more like the improve version of the MG18 than the P17.

There is no question these are Vifa drivers.

Here is hoping they release ScanSpeak Discovery versions of the Peerless Exclusives (starting with the 4" 830881 and 8" 830884), except with a black Nextel finish. Likewise the Vifa D26NC55 tweeter.

edit: Add another to the wishlist, the 8" XLS 830491 aka 205WR3911HPLSAL
shown at the bottom of the page at the link:

And I'd like to see them all get painted with durable flat black Nextel "Suede" finish.

If you go to here:
http://www.scan-speak.dk/midwoofer.htm and
http://www.scan-speak.dk/woofer.htm
you will see a whole heap of YUMMY new stuff in the ScanSpeak Discovery.

It looks to me like they are using the old Vifa manufacturing rig, with an almost Peerless type frame, but without the cut sides.

The curves are VERY "Vifa", which for low order,which I prefer, is

If they can do that with fibreglass, they are going to get a more detailed sound than the old poly/mica drivers. Seems like a near perfect compromise.. me very happy !!

I only hope that WES Components gets this new range of drivers, an sell at a sensible price, (if not I will be ordeing from Mad) and that I can keep coming up with "different" looking ways to use them !!!

Here's the scoop - Scanspeak bought themselves back from Tymphany, when Tymphany was sold. In the deal they bought equipment for the manufacture of several older Vifa and Peerles drivers as well. All of these are being manunfactured in Denmark now in Scanspeak's own factory. The older Vifa and Peerless drivers are being relabled as the Scanspeak Discovery line. There may be more to come as well.

I was going to ask what is wrong with it. A scan for $70 seems cheap. IMHO too much crossover. Keep vifa as the "low end", they may end up suffering the GM effect of they start that. WIth companies stepping up like SB Acoutsics, they clearly have competition.

how strong is cone brake up at around 4500hz? other wise looks good.

Why do you suggest that they will require too much crossover? They appear to be pretty nice to work with - certainly a lot nicer than many of the metal cone favorites that we use today. The biggest peak in the passband might be 2db. If you cross south of 2.2KHz LR4, that peak might not even be noticeable. ...but then, maybe I am missing something.

No No,

Its a pretty good driver, you can likely use a simple shallow slope (2nd) with it so long as you tame that brake-up mode. The issue is how will that breakup sound at the harmonics of 2250Hz, and most importantly 1125Hz. That's an extremely important range. I have delt with this on a pair of speakers in the past and ended up with a simple notch filter which tames it.

There is a lot in that price range, it woudl really have to do something special, which I am sure it does if it is wearing a scan badge

do you mean calling all chevy's cadillacs cheapens the cadillac's name?
I could see that analogy. If a 60 dollar vifa is lumped in with a 200 scanspeak by name change..
it would be like a 20000 chevy lumped in with a 50000 dollar cadillac. Kind of what happened with the catera (rememeber that commerical "who is lisa catera") It was a nice car but it suffered in sales.

That looks an awful lot like this: http://www.madisound.com/catalog/pro...oducts_id=1141





Very similar response, also.

Yep, I knew all that.. Glad to see them actually making use of what they have. I reckon , that at the prices I've seen on that Discovery range, Tymphany are going to be loosing sales of their lines. I think they will find that its not quite as cheap to manufacture in China as they thought it was. That surely would bring a smile to my face !

Not sure how I got CA?

The link you posted is to a file on your hard drive. Unless we all have your hard drive we wont be able to see it.

As far as CA, have you logged a travelling cache that may be in CA now?

Very similar response, also.

I found that the 13m/8636, the woven diaphragm version of the 13m/8640 motor, is an excellent driver and there seems to be better consistency. I had use the old Vifa G17RNX-P woven fiberglass years ago and liked it as well. The two had similar consistency. My guess is that the Kevlar/fiberglass diaphragms may provide consistency at less cost while simultaneously having very well-damped responses. There just are no high-Q peaks in most of them. B&W has used woven Kevlar them for years as well. The nature of the weave seems to provide the irregular geometry that helps to control modes.

Actually, that makes a lot of sense !
