Holy **** - beautiful response...

edit: oops, sorry, here is the link: http://www.lautsprechershop.de/pdf/v...er/bgs1198.pdf

Vifa 10 BGS119/8

But, is it available anywhere?

Seems like anytime a driver is REALLY good, you can't get it?

I asume they are not that hard to get at least in central Europe. I can't tell for the rest of the world however.

The new ones from Peerless (also Tymphany) seem to be nice as well, but I don't know whether they are officially available now:

First reaction would be to ask just how heaviily smoothed is that graph?

Doesn't look a bad little unit though, although sensitivity is mediocre.

pretty graphs are one thing; sound in a system in your room is quite a different story.

For example, Fostex is well known for "optimistic" published specs, and the owners of many happy ears are either oblivious or ambivalent to the real world measures which are less impressive than these.

Scott,

Indeed, the bull**** stops when the green flag drops.

However, it could be somewhat realistic. Perhaps they simply engineered the peaks out of the cone by design. leaving them with an albiet mediocre overall efficiency (being that the cone is not made out of a very lightweight material).

When one is not going for balls out high efficiency, the job of making smooth response is easier.

It is the amplifier that gets to have a difficult time with the result.

I am like you: I would wait to hear what happens when the rubber hits the road in a real world living room or on a desktop.

All that said, I am always happy to learn of a small full range driver I did not previously know of. It is such a great genre, and so much can be done for such little cost.

I am personally holding onto my FE87 (not "e") for use in a super non pretentious open baffle desktop audio system. spectacular little things.

Clark, I had to manually edit your post when you tried to skirt the censor. No swearing.

Well, I couldn't find them for sale in Europe or otherwise, even if you can't read the language, it's not hard to tell when a website is showing them for sale vs. just talking about them...

I'd like to get my hands on a couple of those.

I don't think Vifa is known for doing that, I think their graphs are accurate mostly? (Not like the infamous Tang Band, which seems to use people from the marketing dept. rather than engineers to make their graphs)

Doesn't look a bad little unit though, although sensitivity is mediocre.

Well, if we were to use it on our desks as a PC speaker a cheap little T-Amp would even have enough power for pleasant volumes...

Sure, but, it's a small driver so good dispersion, goes low enough to use with a small subwoofer, seems like it would be a good candidate for GREAT desktop/"PC" speakers, say, a tiny MTM w/a 3/4" rear mount tweeter?

For example, Fostex is well known for "optimistic" published specs, and the owners of many happy ears are either oblivious or ambivalent to the real world measures which are less impressive than these.

I understand the reasoning behind the no swearing rule...
It would especially come into play in a cable burn in debate.

Thanks,

Debate about burn in? What debate? I'm just amazed how many persons put their speaker cables in the wrong direction. Very bad for electron flow. Especially those jumbo bass electrons.

Some of these Viva BBs have already been tested by the two German speaker DIY mags. Will have a look for graphs and the address of the distributors.
