Thanks. So do you think in this case, with an 18mm thick front baffle, that it is necessary?
Hmm wish I knew this before I had all the wood cut
.Is using mdf going to have that much of a negative effect?
Is it worthwhile lining some of the interior such as like in this pic?
An externally hosted image should be here but it was not working when we last tested it.
Absolutely! They will sound more open! Although I must admit that I "forgot" to do it in my BIB
in the rush to get them home. Anyway, it doesn't take long time to do it.I also prefer chipboard instead of MDF but don't grieve over your choice. Finish it and it will probably not be your last attempt of DIY. Next project choose plywood or chipboard and make your own conclusion!
Good luck!

wixy,
stop gnashing your teeth. Any box consisting of more panels than a six panels speaker coffin has enough bracing to minimize any problems. It's more a question of availability and money to choose what you buy. Depending on what colour/finish you want, some materials are trickier than others, that's the biggest grief.

Being my first project, im worried about every little detail hehe. Well, i've began the construction today so no stopping now!
Testarossa, I have a question for you, or anyone else who knows.
Referring to the plans: ://www.fostexinternational.com/docs/speaker_comp/pdf/recom_enclose/208ez_enclrev.pdf
Is Part 22 (of which there are 2 pieces) supposed be aligned with Parts 23 and 34, i.e. 88mm from the inside edge of the side panels?

Looks like parts 22 are mainly there to strengthen part 9. Inserting them at different distances from the side panels may be better for your piece of mind (re standing waves), but don't lose sleep over it. Parts 25 and 26 are a different kettle of fish. Fastening them edge on instead of flat will help to keep the rear panel from having a merry dance - that's a source of sound you don't want.
Thanks for the tip, though it seems I keep doing things ahead of asking advice on the forums, because I already glued parts 25 and 26 last night!
Regarding the fe208esigma cabinet design, I was told that I should consider using 'corner reflectors' where the horn is folded, because without I would get reflections back up the horn.
Is there a reason why the Fostex design does not use corner reflectors (except the one at the mouth)?

Wixy,
I'm not an expert where horns are concerned, but I believe that it is generally thought that bass frequencies aren't affected as much by sharp corners as treble frequencies, which tend to be attenuated. For full range applications this "passive" filter is a plus where phase concerns can be a problem. Not ideal perhaps, but it works and is relatively simple.

Got another newbie question guys. I just made up a circle jig for my router, however i measured incorrectly and it cuts a circle with a radius of 186.5mm rather than 185mm which is recommended by Fostex.
Is this small difference going to have any effect on anything? Is there some sort of science for the diameter of the driver hole, or is it just that as long as the driver fits, it's ok?
