My New Audio Nirvana Drivers

[awkwardbydesign]

If you want a wide band for mids then how about the SeasFA22, or an Audio Nirvana Super Cast Frame 8"?

Well, the Seas appears to have a rising and jagged HF; the AN 8" also seems to rise, as far as I can see from reviews. In the past I have used Wharfedale and Audax drivers with whizzer cones, and preferred them without their whizzers. As a midrange, I don't need or want a lot of HF. Also I find sibilance issues really, really bug me, where I can put up with other faults.
Also, if someone like Nelson is prepared to give them a (cautious?) thumbs up, then I will consider them. Anyway, I've only just heard about the ANs!
I use Chinese designed and built amps, a TVC from Malaysia and a DAC from Taiwan, so a Chinese speaker interests, rather than discourages me.

I think if you only want to use the LCao as a mid range then you probably don't need me to test them. They should be fine in that application

I know, I was just being cheeky.

Thanks for the info Melon! Can we have a picture of your AN OBs? Just trying to get an idea of what that measurement means.

Also, can you measure the 15" ANs solo?

It looks fairly good. Some flattening of the response and couple of notches in the treble will do wonders.

My dear Melon, you have convinced me to pursue my habit further I have received confirmation from my wife that I am allowed to purchase these when i get all these fets off her desk. WHOO HOO!

 

[Zen Mod]

[buzzforb]

I am glad that sort of thing is accepted here

 

[Zen Mod]

.... if you can't beat them ....

 

[Melon Head]

Get those fets off her desk you messy bastard. Haha

Yes I will do that.

Make sure you don't give anything away notching and stitching and trying to make it pretty. I was considering the AN15 with either 15" beta or the Pro A Nelson mentioned.

 

[Melon Head]

Go for the Pro with AN 15
That will be a very impressive setup
Go 1.5 way

 

[buzzforb]

I will be looking for help, of course. I should have a b4/b5 setup by then. Right niw its just on a breadboard. I need to figure out Nelsons bass boost circuit. Any ideas?

 

[Melon Head]

I used 40Hz on mine. The rest is just 1.5.5 doing its job

 

[buzzforb]

Do you have a circuit diagram?

 

[Melon Head]

Here is the circuit. This is for 20Hz bass boost. 40Hz is enough for me

 

[buzzforb]

Thanks. Is this attached to the end of the lowpass?

 

[Melon Head]

yes after your low pass filter

Here is what I am playing with at the moment
