I like the way it handles vocals and most importantly, piano.

If you need more bass, ad a sub fosfex Hz and possibly a 1st order high-pass filter for the Fostex, uF or more. 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. Impact on frequency response of mid LCR circuit red and blue and the RC circuit in parallel with the bass series coil yellow. Fostex FEE fullrange drivers.

These drivers can do things few other drivers can do. Step response showing almost time-coherent performance and a smooth decline from the FEE driver. As announced in the heading, the term “high-efficiency mini” has to be taken with a grain of salt.

fosttex The minor peak at 5 kHz is the leftover from the FEE peak, damped by the 0. Point of crossover is a little above 3. 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 This looks really good.


Fostwx 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. Do not forget to chamfer well around the FE driver hole.

The speaker handles female vocals very well. The response from left and right speaker after installing the final crossovers.

Fostex has a large program of fullrange drivers and from searching the web, they appear to have a mixed reputation. Yes, it can be tuned to high Tostex, but the price to be paid is low-end extension.

I add two rubber strips under the board and fasten it with two screws. CSD of final set-up.

After finalising the crossovers fosgex having the speakers driven by 20 watt PSE triode amps, I have to say I’m positivily surprised by these tiny Fostex driver. Now, comparing manufacturer’s frequency response data with real-world measurements is always fun – or sad – because quite 126sn we’re presented a lot of dreamwork and it takes some decent smoothing to create the graph from Fostex.

The smooth decline from kHz appear to be a sharp dip starting around 16 kHz. Individual and summed response of drivers through crossover and response from inverting tweeter yellow.

I’ve seen the FEE driver used in fstex horn-loaded cabs – and I wonder how it sounds. I’ve tried cross-calculation on the Fostex data right and something juts doesn’t fit.

I would have been highly surprised if the FEE had looked as good as claimed because we’re fostexx used to manipulated marketing frequency response graphs. For better or for worse. Subjectively it has a nice bass presentation, but it doesn’t go deep. Frequency response again and port response blue.


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

All technical questions at troels.

Due to the large magnet, it needs space to breathe. 126n FE driver Fostex frequency response and impedance profile. 126dn would be much too bright. For crossover kit, please contact Jantzen Audio at contact jantzen-audio. No big surprises in the crossover layout.

Can be glued in place after fixing the crossover board to the side panel. I’ll try this later. 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”.

I think that one of the problems may be that these drivers actually are used fullrange. 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.

Driver placement on baffle. No need to flush mount the Fostex driver contrary to the ribbon tweeter that certainly must be to perform optimally. At least it seems we can agree on one thing: Well, from Fs to 5 kHz it really does look good, but the peak at 6.
