Cross-calculation on own data looks fine, but Mms is significantly higher and Qt fortunately much higher making a vented cabinet more appropriate.

Yes, it can be tuned to high SPLs, but the price to be paid is low-end extension. Fostex frequency response and impedance profile. I’ve tried cross-calculation on the Fostex data right and something juts doesn’t fit. A 80 x mm board will take all the components and fit into the rear part of the PE cabinets, that is if Driver placement on baffle.

I’ve seen the FEE driver used in huge horn-loaded cabs – and I wonder how it sounds. For better or for worse. The apparent dB sensitivity cannot be achieved in a small vented construction. Well, from Fs to 5 kHz it really does look good, but the peak at 6. Impact on frequency response of mid LCR circuit red and blue and the RC circuit in parallel with the bass series coil yellow.


Frequency response again from 2. Fostex FEE fullrange drivers.

A midrange 126ej 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. Don’t play them excessively loud, because they can’t. Point of crossover is a little above 3. The response from left and right speaker after installing the final crossovers.

The smooth decline from kHz appear to be a sharp dip starting around 16 kHz.

Here we have the crossover board well away from the driver magnets. Step response showing almost time-coherent performance and a smooth decline from the FEE driver. Drivers in this category often have a dB rise in response towards higher frequences and the use of a whizzer cone on some ofstex the drivers may produce a harsh beaming treble.

As for the W11XT miniI have to warn that 64 square centimetres of membrane, do not – and should not – move a lot of air. However, placed on a bookshelf, some room gain is achieved a more balanced presentation is possible. rostex

These drivers can do things few other drivers can do. Fostex has a large program of fullrange drivers and from searching the web, they appear to have a mixed reputation.

I think that one of the problems may be that these drivers actually are used fullrange. Can be glued in place after fixing the crossover board to the side panel. I add two rubber strips under the board and fasten it with two screws. If you need more bass, ad a sub at Hz and possibly a 1st order high-pass filter for the Fostex, uF or more.


No big surprises in the crossover layout. 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 the spectrum. For crossover kit, please contact Jantzen Audio at contact jantzen-audio.

Subjectively it has a nice bass presentation, but it doesn’t go deep. I like the way it handles vocals and most importantly, piano. 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. Frequency response again and port response blue. As announced in the heading, the term “high-efficiency mini” has to be taken with a grain of salt. The FE driver Fostex frequency response and impedance profile.

After fostdx 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.

The speaker handles female vocals very well. No need to flush mount the Fostex driver contrary to the ribbon tweeter that certainly must be to perform optimally. The FEE has a crisp, speedy presentation with no 126fn and from the tuning shown below it has lots a presence and “let-me-shown-you-what’s-on-this-record”. All technical questions at troels. Listening to the FEE fullrange, this peak is fosex audible and creates at lot of sibilance on vocal recordings.
