The Fostex FEEn is a mm (“) 8 ohm, 45 watt, full range driver that features an mm strong ferrite. I have had the FE en drivers for almost a year in and out of the same If fostex could make a driver with the FE and the FF series together I.

The minor peak at 5 kHz is the leftover from the FEE peak, damped by the 0. However, placed on a bookshelf, some room gain is achieved a more balanced presentation is possible. Fostex FEE fullrange drivers.
Yes, it can be tuned to high SPLs, but the price to be paid is low-end extension. For crossover kit, please contact Jantzen Audio at contact jantzen-audio.
A midrange notch filter is needed to smooth the Hz range and the bass series coil is paralleled by an RC circuit further reducing the 7 kHz peak. These drivers can do things few other drivers can do.
Fostez paper cones and large magnets strongly indicate we’re into a special corner of hifi where opinions easily divide into anything from praise to rejection. No big surprises in the crossover layout. I add two rubber strips under the board and fasten it with two screws.
All technical questions at troels. Can be fostexx in place after fixing the crossover board to fostxe side panel. As announced in the heading, the term “high-efficiency mini” has to be taken with a grain of salt. The FEE has a crisp, speedy presentation with no ringing and from the tuning shown below it has lots a presence and “let-me-shown-you-what’s-on-this-record”. The response from left and right speaker after installing the final crossovers.
I would have been highly surprised if the FEE had looked as good as claimed because we’re so used to manipulated marketing frequency response graphs. At least it seems we can agree on one thing: CSD of final set-up.
Fostex frequency response and impedance profile. Well, from Fs to 5 kHz it really does look good, but the peak at 6. It would be much too bright. Subjectively it has a nice bass presentation, but it doesn’t go deep.
This looks 126fn good.
Here we have the crossover board well away from the driver magnets. Listening to the FEE fullrange, this peak is clearly audible and creates at lot of sibilance on vocal recordings. I think that one of the problems may be that these drivers actually are used fullrange.
The FE driver Fostex frequency response and impedance profile.
Frequency response again from 2. Step response showing almost time-coherent performance and a smooth decline from the FEE driver. I’ve tried cross-calculation on the Fostex data right and something juts doesn’t fit. For better or for worse.
Fostex has a large program of fullrange drivers and from searching the web, they appear to have a mixed reputation. Due to the large magnet, it needs space to breathe. No need to flush 1266en the Fostex driver contrary to the ribbon tweeter that certainly must be to perform optimally.
A 80 x mm board will take all the components and fit into the rear part of the PE cabinets, that is if Point of crossover is a little above 3. After finalising the crossovers and having the speakers driven by 20 watt PSE triode amps, I have to say I’m positivily surprised by these tiny Fostex driver.
Driver placement on baffle. Impact on frequency 216en of mid LCR circuit red and blue and the RC circuit in parallel with the bass series coil yellow.
As for the W11XT miniI have to warn that 64 square centimetres of membrane, do not – and should not – move a lot of air. Drivers in this category often have a 12en rise in response towards higher frequences and the use of a whizzer cone on some of the drivers may produce a harsh beaming treble.
Do not forget to chamfer well around the FE driver hole. Individual and summed response of drivers through crossover and response from inverting tweeter yellow. I like the way it handles vocals and most importantly, piano.
