Thanks for the info. I guess I'll order a bunch of them and see. Worst case scenario I don''t like them, sell them used for half the price and only lose about $80.
If anyone has any further thoughts, please don't hesitate to post them.
By standard calculation this would give an xmax of .15 mm.
Do these motors have stray flux that gives 70% of max BL at much larger excursions?
It works the same both ways; either way measures when the length of VC in the magnetic gap strats to diminish.
I agree that actual measurement of 70% BL is what matters, as you said (and I alluded to).
The above notwithstanding, I hope it works
Hey, maybe DIYMobileAudio is still looking for someone new to run their Klippel testing. Or maybe we can convince Zaph to test it...
Edit: Whoops, messed up the quote. Fixed.
Ive used the ns6 in a couple of projects, with good results on both. It has a nice smooth midrange and decent bass for a 6. For bass, a large ported box (1.3cf or so) and tuned to 40hz works nice.But thar's per driver, can get kind of big with multiples. You can go smaller if not so greedy on the bass.
If one is planing to use subs, then one can use these in small sealed boxes (the f3 is around 90Hz in 0.25 cf), which is not too bad.
I have used about twenty of these drivers for various projects, and they are superb!!!!! One must use them in the right place. They are not a woofer that will fill a room, but reproduce the vocal range with outstanding clarity and presence.
We used six in a line array with flanking line array tweeters and were totally amazed. We crossed over to a pair of 12" sealed subs at 180hz 24db oct. For the tweeter line array's we used eight Aura NS6-255-8A per channel. We crossed these over at 3.2khz at 12db oct.
We are driving these with two custom j-fet monoblocks, good for 500wrms and gobs of current.(big 2kw power supplies with over two farad of capacitance on each power supply rail of 86vrms each.
I cannot imagine a better performing midrange driver. Extremely dynamic and very fast. Rugged and very well built.
