There's your graph.

Happy New Year to everyone! Be SAFE!

with a response like that (plus the cost differential), my 166 ESR is starting to look like a steal..

makes me wonder though if that massive dip at 550 Hz is a measurement error (courtesy of a reverse phase reflection). If so then it starts looking better - but more as a high eff. midbass driver than a fullrange driver.

Agreed. I reckon I'm going to take the measurements with a pinch of salt until I see something else which confirms or disproves them. They should be good. I'd be very surprised if the were not.

I wonder what would happen if Fostex bolted the FE166ES-R motor to the 168ESigma cone and basket (with appropriate other tweaks of course)... just idle speculation of course.

It appears to be designed for use in a large front horn with the rising respoonse. It also appears that it will need a tweeter (and probably a woofer if you don't build a mammoth front horn) if it is front loaded

Sounds favourite. I await the Fostex recommended enclosure plans with some interest...

Hi,

the German Fostex distributor informed me today that they will receive a couple of FE206ES-R for the European market. Prices are still not fixed yet but they promised that the price will be "attractive". As soon as I know all details I will take pre-orders.

Regards
Thorsten

If i enlarge my den... i want to buy an 8" fostex and build a beautiful back horn. This driver seems like a fun one to work with.

Peace,
Godzilla

Zilla -did you forget the golden rule of DIYHifi?

'When you buy a new house for your hifi, make sure it has a decent sized shed. Then you've got somewhere to sleep.'

Cheers

I like very much my Supravox field coils on open baffles but sometimes I wish I had a more massive sound. Do you think these drivers will give me that (in properly built horns)? I could build these and switch between the OBs and the horns as needed. Or should I look into something like the Big Fun Horns? Or maybe justa a three way system.

BTW I use 8 watt 300B SETs.

thanks,

xavier

Default European prices for FE206ES-R fixed

Hi there,

the German Fostex distributor informend me that they will receive FE206ES-R end of February or Beginning/Mid of March. The price will be 250 Euro per unit. For those who might say "why so expensive" compared to Madisound price, an example:

225 USD per unit = 450 USD/pair (US price is always without tax)
shipping cost approx 100 USD/pair
after Euro conversion = approx. 460 Euro (depending on actual rate)
plus 4% customs = approx. 480 Euro
plus 16% tax = approx. 555 Euro (maybe higher in other EU countries)

Bottom line: 250 Euro/unit is a quite "good" price within Europe. Stock will be limited because FE206ES-R was only intend to be shipped to USA!

Regards
Thorsten

MathCad predicted response of the FE206ES-R in the recommended back horn, without stuffing applied. This is approximate as these Fostex Factory horns are really a series of expanding QWRs, which I suspect affects the results, and I didn't take a perfectly accurate measure of the overall horn length. However, I tried some variations increasing and decreasing length in 5" increments each way, and the results didn't alter vastly. I've no idea about the response on the enclosure diagram since it doesn't say how they were taken. Better than I was expecting, though some fairly hefty stuffing will be needed to flatten out the response.

Best
Scott
