In my opinion the FX is worth every cent you pay for it. Created 5 May The BSC is necessary, otherwise the sound isn’t balanced. The wiring must be in place and the hole in the back for connecting the wire with the BSC has to be sealed. Small group and acoustic music sounds wonderful. The FX will need a little help on the bottom end.

Fostex FX 5 inch Full Range Speaker | Loudspeaker freaks
King and asked him to have a look at the simulation I had completed. Also, I placed some felt behind the driver and at the end of the line to avoid reflections. The goal was to let them go down to about 50 Hz.
On the Fostex data sheet they show a flat frequency response without great peaks and drops. Of course the bass doesn’t blow you away, but 50 Hz is there and it fills my room with music. When the recording is good for example ‘Songs from the last century’ by George Michael and the recordings from Norah Jones the artists seem to be standing in front of you.
The enclosures finish consisted of sanding 60, then and then grit sandpaper and raange treatments “hard wax oil” that fires up the color of the wood and protects the surface. Before I closed the box with front and top there were four things to do.
Fostex FX – Fullrange buy at
Searching a smaller driver the Fostex FX, a 12 cm fullrange unit caught my eye. The TQWT enclosure gets good low end from this little driver. The enclosures were made using 15 mm birch-multiplex, the front baffle and the top is 19 mm beech, and the inner plates are 16 mm MDF.
The Fostex FX speaker driver is well balanced, with a relaxed sound, detailed midrange and good highs also very well assembled. However, there are compromises with fullrange drivers; little drivers have disadvantages at the low end and bigger ones at the top end. In my opinion the FX is worth every cent you pay for it.
The BSC is necessary, otherwise the sound isn’t balanced. There is not much information available for this driver, but the feedback from people who have fosted was positive. The two panels out of aluminum on the front and top are anodized in black and covered with a shiny clear coat.
The wiring must be in place and the hole in the back for connecting the wire with the BSC has to be sealed.
Last update 14 April Naturally you can use material of a different thickness, but be sure to adjust the dimensions in the plan. First I attached nylon strings between the sides to keep the damping material from falling to the bottom. I began to tune them by ear until I was satisfied with the music coming out of the speakers.
Be sure to seal the box carefully. I decided to give them a try and was surprised with the sound quality!
Fostex FX120 Fullrange Speaker Driver (Transducer)
The FX will need a little help on the bottom end. I have no measurement equipment, but what I hear seems to correspond with the simulation. Looking for more information about fullrange drivers, I found the Mathcad worksheets by M.
At first they were a little bit harsh but after about hours they smoothed out. With his feedback “I think you have a design” I want to thank Mr. Small group and acoustic music sounds wonderful. Of course they did not play as loud as the bigger two-way speakers that Foshex built before, but something else was fascinating.
For the base-plate I found a granite plate at a stonecutter’s store, he made them for a moderate price for me. King for his kind help and advice I made some test enclosures out fupl chipboard. Afterwards I contacted M. I was surprised with the performance of this driver.
Fullrange drivers seem to play music with more coherence, more life and they sound more direct.
