audio nirvana super 8

[jeeracing]

Hi Guys.

hi got a pair of audio nirvana super 8 (steel frame) last week.
It was just for fun because I never work with that kind of Full Range.

first of all, I put it in a 50L BR box for testing it.

first impression.. "sorry" I dont realy like it. it's so loud in the upper med and high, sound agressive, uncontroled (to my tast) non-realiste sound.

so, I just want to understand why it's sound like this.

-it is just a personal tast ?
-that driver is not that good?

do I have another option to love them ? notch filter ?

If somebody have an idea for me, let me know.

Jee.

I would stuff inside the box with alot of suited blanket, (as 30 to 50mm) etc to raise up the bass.
Dry, bare wood wall is used only in pro audio spaekers.
Good luck

I have a pair. On axis the response rises above 1KHz, so you might consider
a -6 dB or so shelf at 2 KHz.

You can put that together with a coil in parallel with a resistor, those then
in series with the driver. Typical values for the coil would be 1 mH, typical
values for the resistor maybe 8 ohms. Figure on having a .5 MH and a 4
ohm resistor handy to try.

If your preamp has a bass control, that will probably take care of the rest.

thanks for you ideas.

my test box is already damp. this is a box waiting for painting on a 3 way project.

also. the bass is quite good for me. the problem is realy the med-high.

so, nelson pass, if you have a pair... I'm not crazy ?

You would be crazy if you didn't try it. Yes, it needs a bit of taming, but it really is a super driver.

Hello,
i made a few satellite horns
Trumpet, Horn, Schalmei
you lift the area below 800 Hz,
but you need a sub below 100 Hz.

Or take a view to my double horns:
Saxophon, RDH20, Posaune XL
all with rear invers +- changed driver,
Monacor SPH-210, bass down ~30 Hz,
the AN8" is more a horn driver than BR.

My AN CF 12's are sensitive to insulation size, type and placement so experiment . I tried a few insulation things that didn't help and quickly pulled them out going back to the simple original CSA reccommendation.
The 8's probably want a larger box than 50 L . I think it is recc. for 80 L.
You didn't mention what amp you're using with your rig.
My tube amp likes the Zobel I added to my AN and the simple contour circuit similar to what Nelson posted takes care of the rising upper mid and top end.

my actual amp is a Tripath 2022 60w

thanks HM for ideas
