Anyone hear about a new Fostex FE126?
 
Ed of "The Horn" fame is quite excited about an improved FE126E model. Sensitivity is bumped up to 94db, but the big thing is a new center plug/dust cap that is giving it extension out to 25khz while retaining the smoothness of the 126/127 FE drivers.

Has anyone heard anything about an upgraded 126 ? The Fostex site still has the old driver FR plot with the early rolloff. If extension really goes out that high, it may be the new full range champ. Sensitivity, smooth but dynamic, good extension, and small size to reduce beaming may make it hard to beat. Just figure out your bottom end solution like with any fullranger and you're done, forget the tweeter.

126/127

I enjoy my 127e in a pipe. I may put them into a smaller mltl in the future tho... for now they sing. Not rated as high eff as the 126 (91 vs 94) but the 127 is flatter when used in a typical ported box. Ed's horn reinforces the low end of the more eff 126 and probably balances everything out nicely im sure based on early listening impressions by folks who have heard them.

The 127e is fast, open, detailed and clear. Im sure the 126 is pretty great too... but needs the back horn to really shine.

I hope Ed doesn't buy them all!

Peace,
Godzilla

I really like my 127's too, but they really do need a tweeter. If the newer model doesn't need one I'm in for a pair and some 126's as well to try a BLH.

Fostex new FE126 seems really good. Ed seems very excited about it and for good reason:
- Half the price of the FE108EZ
- Twice the efficiency (94dB)
- Twice the power (40 some watts compared to 24 w)

The 25 kHz HF extension seems a bit optimistic since it's -12dB or so, following a 10kHz peak, but still quite good.

Considering the price, efficiency and power, it seems hard to justify buying a FE108EZ (except for the nice cast frame).

I'll get a pair and report back.

Robert,

Are you sure Ed hasn't gotten ahold of some newer model with increased extension? The FR currently on the Fostex site rolls off even earlier than the 127 and I find the high end lacking on my 127's. Ed told me it had a solid and smooth top end.

From what I can see, the driver is a stock FE126E (which is quite new by the way).
On axis, 0dB is around 15kHz and drops fast off axis.
HF extension is relative to hearing capacity, and some people won't notice the difference, but some people will. I would surely mate this driver with a ribbon on top, cause what's below 10kHz seems really good on paper.

Did this driver ever materialize? I'd built a great pair of FE127 based fullrange speakers, but sadly now one has a warped voice coil due to a power amp failure (they don't like 55vDC..!) , and Fostex have discontinued the FE127.

I am close to purchasing a pair of FE126 as a replacement..

Any thoughts?

FE126e is not a suitable replacement for the FE127. And now we have the FE126En which, from the specs, wants to see a horn even more so than the FE126e.

I still have some FE127eN which would be a significant upgrade to your existing speakers (if i do say so myself)

If you want to change drivers, and you have sufficient power, the CSS EL70 can be retrofitted into some of the FE127 boxes (ie Fonken Prime is doable)

I am intrigued by your comment about the FE126.
The specs and parameters of the 126 and 127 are very close.
Why do you say that it's not suitable as a replacement for the FE127?

Scottmoose 20th May 2010 10:02 PM

Not when one has a nominal Q of 0.25 and the other 0.43. Both are exaggerated, but by roughly equal amounts. The 126 only has 58.3% of the V[d] of the 127, and a slightly different FR balance. The 126 is also nominally a couple of dB more efficient.
