Question Aurasound NS3-193-8A

Has anybody used these in anything? From what I can tell, they seem like quite nice little wide-range drivers, except for the horrible efficiency (80db 1w/1m). The huge excursion (20mm p2p) would lead one to think that, hey! we might actually get some bass out of a 3" driver! I'd really like to know if that's the case! And if they're decent (decent, mind you. I don't expect them to be great), what might be the best application? They're cheap too...only $19.80 at madisound.

Any information and/or reccomendations would be wonderful! Thanks in advance....

The NS-3 is a good little driver. I've been enjoying a set of Illusus' prototypes for the last couple weeks.

You won't get real bass, but enuff to reach down to a sub if you need to.

We tried them briefly as bipoles.

Impedance curves give an Fs of just under a 100, and the bipole in the same box about 20 hz higher. I plan on adding an aperiodic port to the back baffle to see if i can lower the bipole's impedance peak.

Now using them with a sub. XO currently set to 60 Hz.

Very satisfying performance. Using a BGT GC in a Specialized Kits chassis. They start to strain a bit when pushed. Very cute too.

Very versatile. Cheap & small enuff to use as computer speakers. If you can except its efficiency & loudness restrictions and 100 Hz is good (or you have a sub) these make good mains (make good centres & surrounds too). They'd make a killer mid. if you could find drivers inefficient enuff to suit (or bimap!!)

PS: speakers packing taped to the stands

impedance curve

You can see we didn't quite get the bipole sealed.
