For instance, all new Concerti v2 will feature leather wrapping inside the horn mouth to fostxe any HF content that might still be present in the path. Also, we are still working on the resonant aspect of the enclosure. I guess it’s like concentrated orange juice versus freshly squeezed orange juice. Today we have assembled the perfect team to tackle any project.

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.

I sold him the horn because I did not like the sound anyway it was based on a Fostex FEEZ, a nice driver but too directive and “hard” for my tastes.

Now that was interesting: Speaking of contradictions, the same reverse psychology took place when I designed the Basso the bass cabinet companion of the Concerti.


We basically had to wait for the right tree to fall in order to comply. The design of the cone and dustcap is called hyperbolic paraboloid. It does not swallow energy like raw MDF.

So the corporate focus is working with clients once they’ve fostes that the sound we offer suits them – to get exactly the right product variations. They may even sound hopelessly broken. 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.

He was impressed with the sound and was rostex in selling the same foste to others. I was not interested in building any more of those. The biggest challenge in building the Concerti and all upcoming Gemme Audio products was to find the right people to build it. There’s a lot of tweaking that will be done to extract the maximum transparency that the driver can achieve and I anxiously await your review for further tweaking suggestions.

But after we get the right sound, we have to think about the home into which it will fit. My sample does not sport one.


Could you tell me a fostec more about the Fostex driver? I had wondered if they had gone out of business or moved on to a different style of design. Exotic woods are bred. There was a lot of dicussions and incredulity a few years ago and this is OK. I thought it was the worst speaker I’d ever heard.

Another client requested a very rare and hard-to-find Tiger-figured Anigre veneer. I became aware of Fostex drivers a few years back.

There was no adverse effect on the sound and the ring is still offered as an option. Thu Jun 11, 1: I sold him one horn I built. It’s a wonderful piece of engineering and I guess fowtex one of those examples where art meets science. Using a critically damped design meaning a box with a larger volume of air than what would be required for a max-flat alignment gave us just enough volume to fit the driver and amplifier in a one cubic foot box and still get in-room extension to 15Hz with no boominess, just ultra fast transients.

Not as directive as the bigger fosgex, it has marvelous midrange, fe108fz nice top end and gives credible acoustic bass, which is kind of spectacular considering the small 2.
