if qts is as low as stated and it sounds "bright" without filter in reflex then it may work in RCA-Fan's 186 liter volume (airpsace) horn. Plans are at RCA-Fan's gallery at Audio Asylum High Efficiency speaker forum. This blh was designed for 208 Sigma
do DBR sound more articulate than single vent with cello and bowed bass viola? - if so it might be good for my AN10. The only DBR I tried was some years ago with an 8" SEAS woofer and regular alignment with 2:1 chamber ratio and all three vents the same.

Super 8
Hi I just aquired a new set of super 8.
Kill mids, very good hi.
The bass is a bit shy but sweet..
Note, I cannot speak about the bass right now because I am just mounting them in a very limited space cabinet. I do not expect a loud bass from this cabinet.
I am thinking of making a Folded horn (envelope), or a Horn cabinet.
I have been told that these speakers like horns. Theoretically I would agree by noticing the bass section in my super8.
Has anyone experience with these two types of cabinets, any suggestions?
Horns are 75% efficient and bass reflex only 5%...
If choosing the horns I would like to go for the fostex fe206 design as it has no diagonal wood pieces inside and it is therefore easier to construct.
If choosing the folded envelope I would go for a simple design with only one mid diagonal wood piece.
Any thoughts?

Horn efficiency really depends on the design -75% would be, er, going some. Even Leach, who's math is based around max-efficiency, doesn't universally aim that high.
Yes, they'll like horns; the balance of the FR is tilted very much in favour of that sort of box. I'd be careful about sticking them in the 206 box though. For a start, it's not a great design (the 208ESigma cabinet is much better IMO) and also note that the AN's Vas is much higher than either Fostex unit, so they'll roll off a bit more in the LF in these boxes than the drivers they are designed for.

Depends what you mean by a TL. Different people use the term to mean different things (often exact opposits). A pure TL or a typical tapered, heavily damped line would be dreadful in LF terms with this unit. A resonant line is OK would do OK if properly designed. A horn or variation on the theme would be better though. Jeff ('Zilla) has already suggested a BIB pipe-horn on the thread you started, which when it comes to big bass from a simple cabinet is unbeatable, so if you want an easy build & decent LF power, that would be my first port of call. Much better than any reflex box.
Thank you very much!
I have seen BIBs with much interest. Everyone suggest it for good ammount of bass, yet they are very simple to construct provided that you have a tall enough room.

There are instructions of how to build it.

There are pre-calculated values for the audio nirvana super 8
They have to be about 2.2 meters tall for the super 8 !!! But I guess It is worth it
I have also seen a resonant line made of big diameter pvc, I do not know it's performance but I am thinking of going to the more steady way
