Audio Nirvana super 8
Audio Nirvana super 8 in Fostex double bass configuration cabinet.
very good mid and high freq. good bass.
Nice. Did you have a FE207E in there and just dropped in the AN?
If so, can you comment / compare the two.
no, i never had fostex speaker... it's only an experience for me.
my first fullrange projet, and i'm very happy. my amp is a Trends
T-AMP, the sound is powerful and full of details.
I would like to buy a AN super 8'' speakers, but I don't know which eclosure is the best.
Can you help me?
I prefear a simple cabinet like bass reflex or double bass configuration.
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.
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.
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.
how about transmission line enclosures?
They are much simples. do they perform better than bass reflex for the super8??
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.
In this link
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 :)
