"Getting real, strong 20 hz output from a loudspeaker is no mean feat. Going lower than that is subwoofer territory.
Gemme Audio proudly introduces the revolutionary VFlex technology, based on a unique Focused Pressure Field loading method that extends low frequency reproduction below the human hearing threshold of 20 Hertz using small drivers and enclosures. The new Vivace loudspeaker is our first model based on VFlex technology.
The Vivace are no ordinary speakers and they go LOW, real LOW, lower than 20 hz in most room conditions... That's quite amazing performance for any speaker, but their most stunning feature is not that they go that low... It"s that they can do it with a single 4" driver! Imagine what we can do with a larger driver!"
...
"Gemme Audio is aiming to offer its new VFlex line of full range loudspeakers early in 2007. After many tests and listening sessions, we've finalized the design. Utmost rigidity allied to awesome look and sound will be the hallmarks. We sincerely believe that our VFlex technology brings a revolution to the loudspeaker market. Nobody can imagine the sound of the VFlex loudspeakers when they see the small drivers. Nobody is prepared to hear full 20 hz. output from a 4" driver. But this is all real as listeners and NRC testings can testify.
Here is a comment from a reviewer waiting for a pair of Vivace : "...if you can make it a full range speaker, I think that would be incredibly awesome". Here's another comment from a web forum member : "You seem to have found the audio Holy Grail."
We'll be offering two models in the VFlex line as a start.
For the single-driver, horn sound afficionado, there will be the single-driver Vivace, offering "real" full range sound, from as low as 20 hz up the 18,000 hz, using the Fostex FE108E Sigma 4" driver in a very rigid cabinet, finished in real wood. The next model, called Tanto, will be a two-way tower, using a 6" driver paired to a Vifa ring radiator tweeter, offering bass that rivals 15" driver designs of yesteryears. Both models will offer small tower, resonant-free cabinets with sculpted front panels that are sure to offer a very high WAF!
At this moment, the look and finish are still on the drawing board but photos should be available in early January 2007.
Stay tuned to hear more about the Vflex models going where no other small driver loudspeakers have gone before."

What do you think? I would really like to know how the "VFlex" acutally works?

A friend of a friend is picking these up used. I'll get a chance to hear and measure how they perform🙂

It will be good to have another review. I have heard the FE108e∑ version, it is hard to make that driver sound bad, but VFlex, is after reverse engineering, a poorly designed ML-Voigt variant.
They cam eup with it as a patch for an even poorer earlier design.

Revealing speaker. Subjectively well integrated but there is a dip at the crossover frequency at 2M on axis. Tilting the speaker removes the dip but creates a depression on either side of it. The bass is not great, not the most dynamic and not free from coloration.
The dip in at 60hz on impedance plot is strange to me. Appears like a leaky box that I've seen in my experiments. What is the tuning frequency? Are they MLTL or? The rear port location is around the mid height position.

That is preety much what we saw when we inspected the FE108e∑, a poorly designed ML-Voigt sort-of. It was a bandaid after doing their “horn”.

The Gemme is weird. Maybe he was inspired by this
But I haven't heard these speakers. Maybe they sound nice.

We burned that build. It doesn’t really go much below 100, there are a ;pot easier ways to achieve that.
