working with the Fe127e

[Roemhild]

Hi @ll


there are a few threads with and for the Fe127e. I would like to show how Raffi and I build our Preso and give some more details.

the first steps where to cut with a CNC the parts. Each is 4cm thick.

 

[Roemhild]

After we have had all parts we drilled the parts to clue and screw them together.

 

[Roemhild]

here is the first impession how it will look

 

[Roemhild]

the next step was to build the upper and lower part. The preso is complete screwed, exept the middle. We had to do that so that we could place the front plate.

 

[Roemhild]

Now we have glued the first front plate in. The Fe127e will be placed on it later.

 

[Roemhild]

the second and later visual front panel is also cut out on a CNC. Here we have placed the Monacor SPH 135-KEP

now these are nearly all parts we have used for the Preso

 

[Roemhild]

thw x-over is build in a symmetry way.

finaly two picture how it looks now

and picture #2:

each SPH-135KEP is playing into a 13-14 ltr BR-volume.
the Fe127e is playing in closed 2,7 ltrs.

To get the surface smooth I had to sand every box for about 8-9 hours (with profesional tools ). But I enjoyed every hour now to see how nice it looks and also sounds. The first pair (that I have build) is in my bedroom.



I have tried a similar project with the Fe127. But the Fe127 only needs 0.8-1.1 ltr.

Very nice,

How do they sound?

Hi Josh


I like the sound and I can only recommend to try the Fe127e in about 2,7 ltr if you want/will add a bass under the fullrange driver.

Beautiful work, and a lot of it. Thanks for sharing.

What is the black dot on the Fr127 dustcaps ?

Have you cut open the dustcaps, and/or applied other treatment to the driver ?

 

[Roemhild]

Hi Svein


I have done nothing with the Fe127. The black dot is an original hole.

Hi Till,

really like your designs. What makes me wonder: The fe127e does not simulate very well in enclosures that small. The frequency response gets a little bump at ca. 230 Hz ( which does not matter) and the transient response gets very slow in the simulation. I know that the TS from Fostex are not that exact - especially for a well broken in driver but I'm still wondering if the fe127e in that configuration could cope with the speed of the bass units I'm planning to use with those little drivers (Eton 8-480/32HEX). In larger volumes the transient respones looks very much better.

Are there any issues withe the speed of the Fostexes in that boxes?

regards

Flo
