Default yeah.

yeah, Ill have to hear some more of the 8 inch blh stuff. I agree with you on the looks of the 208 cab. it is killer. conceptually makes sense too. especially from a baffle shrinking standpoint.

have you heard the recommended enclosure for the 206e?

my next big cabinet will be for 208es-r.

none till then. have to finish my thesis.

You and me both -I've got another 25 months of my PhD to go yet.

Yes, I've heard the recommended 206 cabinet. Not impressed. Even less so when I decided afterward to run a few MathCad sims (I apply the same comments to the 166 BTW enclosure too. This cabinet type is not one of their best). The 208 box OTOH I heard recently at a friend's house, and came away very impressed indeed. With live Metallica, the floor was shaking (and I don't mean just lightly quivering) and it kicked you in the chest like a PA bass bin. Massive down to about 36Hz. I can understand why the mouth is hanging in mid-air when it's got that sort of grunt in the LF regions.

I have my 206Es in the 208EZ Fostex-recommended BLH and I love them.

Not that that's worth anything...

And I have 206`s in recommended horn and love the sound and look. I veneered them in red oak and staines the inside of the mouth black. I also have 206ESR in recommended horns, veneered in walnut, while they sound more detailed and extended than the 206`s, the 206`s get more compliments on looks than the bog 206 ESR horns do. Maybe because the 206ESR have a T90EX on top with exposed wires but they are on solid walnut mounts I like them both, 206ESR are in a 2 channel triode PP, with analog source, and the 206`s are mains in a HT system that I use 2 channell often as well. Both sound great and look good, but I spent alot of time finishing them. There`s my biased opinion, FWIW.

I can't belive it!
today I get my hand on some old supertweeter magnets and I put them on the back plate of the fostex and surprise of surprises I get more middle/bass. ah now the voices are full and the instruments like electric bass ca be heard better. I noticed the cone is now moving less also....

Now I'm in search of bigger magnets

Question: Can I put them right in the center of the back plate of the speaker without the risk of coil overheating? I suppose yes because I don't see any vent on the backplate, right?

You should be fine if it's not blocking any vents. As I mentioned before, it's not a very common tweak these days, but it can work. Sounds like it has for you anyway!

Of the Factory designs, the Sigma is the best best from modelled response & I can vouch for it's subjective performance. Goes far lower than the standard 206 cabinet, has a much flatter response. I still think it looks prettier too. Let's face it -you can't really argue with a pair of cabinets that look like this can you?

Kofi -didn't know it was you running the 206s in the 208 cab. Did you move up to those from the 108s? How does your floor stand up to the LF output?

Default "Moray James tweak"

Something anybody running FE206E's ought to seriosly consider trying _grin_

I used to run FE206E's in my Azurahorns.

Moray James sent me a cool tweak - basically, just ground either the negative or positive side of the speaker terminals to the basket (chassis)

Easy to try - take a jumper with alligator clips on each end - put one clip on the chassis and the other on the red or black terminal.

There is a difference in the sound - at least with my system and quite a few others

There seems to be a slightly ( roughly 2DB+- ) lower output.

Also, maybe a tad less dynamics.

However, the overall result is a more pleasing and accurate sound.

May be different for different amp topolgies - dunno.

Just about everybody that heard the FE206E's preferred them in tweaked mode.

IIRC, mine sounded better with the jumper from the negative terminal grounded to the chassis
No longer powered by Linux - not enough apps and cross platform integration - but maybe one day

I started out using 206E's in 208 cab's and thought they sounded great. I switched to 206ESR's but kept the 208 cab. I was looking for a bit more DB from my 45 SET amp. The 45 is doesnt have much power so every little bit helps.
I also grounded the negitive terminal to the frame on both drivers, it made difference that I liked. Phase plugs for the 206ESR was the finishing touch.
Just once I wish someone would call me "Sir" without adding, "you're making a scene"

greeting Ladiies and Gentlemen, please dont forget the Dallas II designed by Ron Clarke and I built this horn for the 206.It has a great bottom end and I implemented the folllowing 1.grounding chassis to -ve
2.Phase plug
3. fluffy baff gently wedged between whizzer and main cone
4. damp chassis(masses of blutack)
5. polystyrene disk(1 inch) on back of magnet
and in then end I felt I was pretty daarn close to getting the best out of this driver without resortind to drastic measures such as surgery on the whizzer or using coatings or totally desperate measures like notch filters(only kidding).I have since moved onto visaton b200 in open baffles and haven't looked back. Anyway i hope my post is useful in some way cheers fergs

bluetack? is it a product for idraulics? It can be removed after the application just in case I want to go back?
The target is to lower the resonance of the basket, right?

Thank you to all, now I don't have to work again to make new cabinet, I put a lot of work in my BR box, they're strange and I like it so much.

Butt, I agree some horn looks very good, very aggressive also
