I was shaking my head, reading this article in Hobby HiFi!

In the same article, they want you to make believe, that the Visaton FRS8 for only 12 Euro is a fine speaker.

And for my experience: this driver is not a HiFi speaker, imho!

BTW: The FE108E Sigma is a fine speaker in the cornu spiral horns!

I attach fronthorns, to linearize the "hole" around 1kHz.

It's a near-field measurement. It cannot be trusted above a couple hundred Hertz. It would be much more interesting to see one or two meter results.

Are those enclosures based on the Fostex Factory design for the earlier non 'E' Sigma? I like.

Best

No, this is a patented german speaker. You may have a look at:

http://www.cornu.de

an interesting inside view here:

http://www.cornu.de/minispir_t.html

You can find the patent description online, in pdf format, but the server seems not to be up and running actually.

Go to http://www.depatisnet.de


Click on "Recherche"
Click on "Einsteiger"
Type in "Erfinder" daniel ciesinger
Type in "Suche im Volltext" "planare führung"

and you'll find it, looking for the PDF-button.

Franz

The HobbyHiFi magazine is salesman of kits of the published designs. For that reason it is bound to the loudspeakers that sell and Fostex is not among them. It is a campaign to discredit the rival.

When Bernd Timmermanns was in Klang&Ton was an honest person.

This is a graph of the Fostex FE108EZ horn box.

Greetings,

according to the HobbyHifi-website the measurements are made in a 6m x 6m x 6m room at a distance of 1m. The drivers are placed on the ground, which gives a 6m x 6m baffle. Below the driver there's a 1000 liters of space. Measurement distance is 1m, voltage is 2.87V.

Source: http://www.hobbyhifi.de/Aktuell/Mess.../messraum.html

Cheers, Elam

i hear the JX92 are about $150 each while the 108 sigma are about $100 each.
