Fostex FEEZ ‘Sigma’ – € : , Loudspeaker shop

When we decided to finish the horn with leather, we had to find the right “maroquinnier” and so on. This review page is supported in part by the sponsor whose ad is displayed above.

Thu Jun 11, 2: Hi Guys, Trying to get that kind of bass out of such a small driver seems like a pretty bad idea. Sound is the core of Gemme.

Later on, I experimented a lot with both horns and really small drivers and enclosures such as the Philipswhich — apart ce108ez the full range — was the best-sounding driver. Tanto I guess Tanto’s inside, is the same as Vivace I will start soon The driver is mounted on a birch plywood plate finished with a compound called Effecta Gomma a form of rubber coating.

After all those headaches, we finally found the properly dedicated, quality oriented bunch of artisans. There was some discussion of the Gemme speakers on the Internet forums a few years ago in which claims made by the manufacturer were met with some skepticism. You just might forget fussing over traditional audiophile minutiae and instead re-explore your existing record collection and fpstex even expand into other music genres.


I remember the first time I heard a horn loudspeaker. I got into art school at 16 and fee108ez that time, all students were either members of a band, groupies or roadies. I was not interested in building any more of those.

I could feel the music in my chest.

I listened casually over a couple of hours and then suddenly, somehow, those aforementioned colorations didn’t offend gostex much. We also work with other players, namely from the Montreal Audiophile Association, a very active bunch of guys who love to test new ideas and products just for the fun fsotex discovering things good and bad. I don’t see much about the design on the Internet anymore so I assumed that they Gemme had moved on to a different design concept.

There was a lot of dicussions and incredulity a few years ago and this is OK. A few years ago I spent some time running simulations of the design based on my reverse engineering of it from info I found on the Internet. Vivace is an Atelier with a closed hornmouth. Vivace, Tanto and Katana. They are CNC machined out of machine-grade MDF sheets and heat-pressed with heat-activated urethane glue to form a solid block.

It’s a fosetx piece of engineering and I guess it’s one of those examples where art meets science. There is a review coming out soon on www.

There was little in the way of precise imaging, soundstaging or any of the standard qualities one expects of a high-end design. Premier three-tier, filled with sand Powerline conditioning: So the corporate focus is working with clients once they’ve decided that the sound we offer suits them – to get exactly the right product variations.

My favorite instrument is piano, especially the concert grand. I guess that’s what Gemme is all about. So I like horns for their dynamics but I also enjoy sealed and reflex and TL enclosures. One at a time. Why the shape and patterns on the cone, dust cap and surrounds? The real thing is harmonics integrity, meaning the ability of a single small driver to reproduce the sound of fundamentals and their harmonics in a pure and coherent way with no crossover reconstruction.


I guess it’s like concentrated orange juice versus freshly squeezed orange juice. This compressed air naturally wants to decompress so it acts on the horn path’s volume of air. Hi Gio, I started by modeling the “first horn” design. In order to get some bass output, the Sigma as well as all Sigma models and most Fostex drivers in general needs to be loaded by a horn enclosure.

At this time, the Katana model has a lot of interest because we used fe1008ez midrange Accuton driver to generate the fullrange sound. Not as directive as the bigger siblings, it has marvelous midrange, a nice top end and gives credible acoustic bass, which is kind of spectacular considering the small 2.

For example, one Toronto client requested a special Raspberry Red which we call Saturn Red, Saturn being the client’s first name with black leather interior. So we had to find ways to alter the MDF’s damping.

No enclosure to speak of, just a set of panels and curves giving an absolute kick. A lighter cone also makes possible the use of a smaller voice coil. The Revelator has a voice coil inductance of 0. The speaker is loaded into a very small sub-enclosure less than half a literthe compression chamber. Page 1 of 3. Connectors are Cardas OFC. For instance, all new Concerti v2 will feature leather wrapping inside the horn mouth to kill any HF content that might still be present in the path.
