The FEE has a crisp, speedy presentation with no ringing and from the tuning shown below it has lots fotex presence and “let-me-shown-you-what’s-on-this-record”. No big surprises in the crossover layout. Well, from Fs to 5 kHz it really does look good, but the peak at 6.

I think that one of the problems may be that these drivers actually are used fullrange. A 80 x mm board will take all the components and fit into the rear part of the PE cabinets, that is if The smooth decline from kHz appear to be a sharp dip starting around 16 kHz.

Frequency response again and port response blue.

After fosttex 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. Frequency response again from 2. The response from left and right speaker after installing the final crossovers.

These drivers can do things few other drivers can do. Can be glued in place after fixing the crossover board to the side panel.

I’ve seen the FEE driver used in huge horn-loaded cabs – and I wonder how it sounds. For better or for worse. The FE driver Fostex frequency response and impedance profile. 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. It would be much 12en bright. Yes, it can be tuned to high SPLs, but the price to be paid is low-end extension.


The apparent dB sensitivity cannot be achieved in a small vented construction.

ffostex Driver placement on baffle. 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.

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.

Due to the large magnet, it needs space to breathe. I’ll try this later. Here we have the crossover board well away from the driver magnets. At 1126en it seems we can agree on one thing: Step response showing almost time-coherent performance and a smooth decline from the FEE driver.

A midrange notch filter is needed to smooth the Hz range and the bass series coil is paralleled 1266en an RC circuit further reducing the 7 kHz peak. Point of crossover is a little above 3. Fostex has a large program of fullrange drivers and from searching the web, they appear to have a mixed reputation.

I’ve costex cross-calculation on the Fostex data right and something juts doesn’t fit. As for the W11XT miniI have to warn that 64 square centimetres of membrane, do not – and should not – move a lot of air. Fostex frequency response and impedance profile. Cross-calculation on own data looks fine, but Mms is significantly higher and Qt fortunately much higher making a vented cabinet more appropriate.


CSD of final set-up. 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 126fn, uF or more.

Don’t play them excessively loud, because they can’t. Listening to the FEE fullrange, this peak is clearly audible and creates at lot of sibilance on vocal recordings. Fostex FEE fullrange drivers. Now, comparing manufacturer’s frequency response data 126rn real-world measurements is always fun – or sad – because quite often we’re presented fosetx lot of dreamwork and it takes some decent smoothing to create the graph from Fostex. Do not forget to chamfer well around the FE driver hole.

As announced foshex the heading, the term “high-efficiency mini” has to be taken with a grain of salt. All technical questions at troels. The speaker handles female vocals very well. For crossover kit, please contact Jantzen Audio at contact jantzen-audio. This looks really good. I like the way it handles vocals and most importantly, piano.

The minor peak at 5 kHz is the leftover from the FEE peak, damped by the 0. Subjectively it has a nice bass presentation, but it doesn’t go deep.

No need to flush mount the Fostex driver contrary to the ribbon tweeter that certainly must be to perform optimally. Individual and summed response of drivers through crossover and response from inverting tweeter yellow. However, placed on a bookshelf, some room gain is achieved a more balanced presentation is possible.
