 Don't know. They look an awful lot like drivers Aura used to use in their long-discontinued computer speaker line, but that's complete speculation.
The NS3's that you have are the lesser ones. Most of 'em have a paper cone and phase plug, though some had the inverted dome of the "better" NS3 as well. The ones that are ~$20 at Madisound (I think they've gone down a bit) have better motors, smoother and more extended treble more similar to the copper-cone HiVi driver, and I think 5x the xmax. (1mm for the surplus ones vs. 5mm for the better ones.) |
Hmm, I think PE stated the xmax of the ones I used as
3mm. I've had pretty good experience with their products matching up to their stated specs (except once when the driver cutout was off - doh!). As I said before, they actually have pretty good bass for a 3" driver. I'm pretty certain they are moving more than 1 mm p-p. I made a RLC circuit for the surplus ones that took much of the brittleness out of the treble. I am interested enough I may have to get some of the $20 ones at some point and compare.
Question - do you get beaming with the treble on your 8" full rangers? If so, how do you fix it? I've noticed the difference in beaming between 3" and 4" and I've always wondered about anything larger.
