Default FE206E Recommended Enclosure

Just getting ready to build the fostex enclosure for the FE206E and had a question about the internal bracing. If someone has built this already I thought they might have some insight.

Link the the PDF of the enclosure

My question is regarding the braces labeled 9, 11, 2, and 6 in the drawing. I can't tell exactly where they are to be positioned by the drawing. Are they on edge in the center line of the speaker? The picture of the built speaker almost makes them look staggered inside.

Thanks for any info

Tim

A natural inclination would be to put them in the middle (the drawing is not clear). This is -- from a bracing point of view -- the worst place for them. I'd offset them at least a bit (ie draw the centre line & put the edge of the brace on the centre line. This should dramaticaly reduce the 1st major bending mode of the panel.

Anyone knows how well FE206E performs in traditional Voigt Pipe? I'm thinking about building one of those because of the simple wood working needs. Would FE207E be a better choice for this design?

I think the 207 would be better in this case. It would be hard to tame the rising response of the 206 in a Voigt. There are other options that may be even better than the 207 though. Hopefully you'll get some good responses here.

Yes, 207 is better suited to a Voigt than the 206... the Q of the 206 makes it like horns best.

Another question is; how well would they perform with solid state class A amp. Just wondering before I collect all the parts to build vacum amp. Is it worth my effort?

Personal experience (on bipole FE127) has the monoblok RH84-style parafeed SE amps trouncing a miniA (except on the bottom).
