About the Aura NS-513-4A

[Luke]

Hello

Aurasound woofers NS12-513-4A seem unavailable for some reasons I'd like to know.
It would be nice to have four of them for the 20-100Hz LF section of a four way project but well... this is life!
So I need something else.
Could the Vifa/Peerless NE315W-04 http://www.tymphany.com/peerless/subwoofers be a good alternative?
Similar prices, similar quality construction, copper cap in gap, stiff cone, low Le and to make it short...equivalent specs.

Up to now, multiple simulations has proven to be quite interesting maybe...even very slightly better.
Looks promising though.
Any of you has non-linear tests and distortion figures or project experience with this driver?
Thanks,

Luke

I may have four new in box- will check this weekend if you're interested.

..unavailable for some reason..

IIRC Madisound said Aurasound was getting out of the DIY distribution business, and they were just going to sell to OEMs.

(I did ask about the little tweeter Aura NT1-204-8D, and they said that should continue to be available. I'm guessing they stock enough to be considered an OEM.)
