If you need more bass, ad a sub at Hz and possibly a 1st order high-pass filter for the Fostex, uF or more. Fostex frequency response and impedance profile. The speaker handles female vocals very well. Do not forget to chamfer well around the FE driver hole. Yes, it can be tuned to high SPLs, but the price to be paid is low-end extension. Listening to the FEE fullrange, this peak is clearly audible and creates at lot of sibilance on vocal recordings.

It would be much too bright. Here we have the crossover board well away from the driver magnets.

A 80 x mm board will take all the components and fit into the rear part of the PE cabinets, that is if Cross-calculation on own data looks fine, but Mms is significantly higher and Qt fortunately much higher making a vented cabinet more appropriate. Subjectively it has a nice bass presentation, but it doesn’t fodtex deep. The apparent dB sensitivity cannot be achieved in a small vented construction. Step response showing almost time-coherent gostex and a smooth decline from the FEE driver.


CSD of final set-up. Don’t play them excessively loud, because they can’t. Lightweight 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. For crossover kit, please contact Jantzen Audio at contact 126dn. All technical questions at troels. I would have been highly fosgex if the FEE had looked as good as claimed because we’re so used to manipulated marketing frequency response graphs. Now, comparing manufacturer’s frequency response data with real-world measurements is always fun – or sad – because quite often we’re presented a lot of dreamwork and it takes some decent smoothing to create the graph from Fostex.

Driver placement on baffle. I think that one of the problems may be that these drivers actually are used fullrange. Due to the 126een magnet, it needs space to breathe. However, placed on a bookshelf, some room gain is achieved a more balanced presentation is possible.

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”. Frequency response again and port response blue. Fostex FEE fullrange drivers. This looks really good. Well, from Fs to 5 kHz it really does look good, but the peak at 6. As announced in the heading, the term “high-efficiency mini” has to be taken with a grain of salt.

Can be glued in place after fixing the crossover board to the side panel.

Point of crossover is a little above 3. I’ll try this later. I like the way it handles vocals and fstex importantly, piano. I’ve seen the FEE driver used in huge horn-loaded cabs – and I wonder how it sounds.


They have a crisp and vivid presentation and there’s enough bass to get a good idea of what is happening in the lower end of fotsex spectrum. Drivers in this category often have a dB rise in response towards higher frequences and the use of a whizzer cone on some of the drivers may produce a harsh beaming treble.

Impact on frequency response of mid LCR circuit red and blue and the RC circuit in parallel with the bass series coil yellow. These drivers can do things few other drivers can do. Individual and summed response of drivers through crossover and response from inverting tweeter yellow. As for the W11XT flstexI have to warn that 64 square centimetres of membrane, do not – and should not – move a lot of air.

Fostex has a large program of fullrange drivers and from searching the web, they appear to have a mixed reputation.

The FE driver Fostex frequency response and impedance profile. At least it seems we can agree on one thing: The minor peak 126een 5 kHz is the leftover from the FEE peak, damped by the 0. The smooth decline from kHz appear to be a sharp dip starting around 16 kHz.
