    NS6-ed

    I have completed testing on 2 sliced Aurasound NS6-255-8a samples and decided to bury the data here. These are unworthy of their own thread. Whoever it was that convinced me to buy these must be deaf.

    3 NS6s baselined showing 3rd order distortion-



    The slit technique definitely works for suppressing the break-up.

    The slits destroyed the peak completely, and reduced the related 3rd and 5th order distortions by the same 8-10 db.

    Sample-5




    What it did not do is make the driver into something I would want to use. I can't stand to listen to them raw or modified.

    There is one big problem that I may or may not address in this round of drivers. Distortion below 1k rises when testing the NS6 at high volumes. This indicates that the glue is too soft(which I suspect), the gap is too wide, or the floppy-coned NS6 is just not suited to this mod.

    MY advice so far- sell the NS6s, keep the NSBs, and cut everything but don't glue yet!

    Apparently not.

    Re: Disregard

    This thread is getting really exciting. I hope you can stick it out until all those slits are fully explored.

    I can't believe you guys would degrade my thread like that!

    Partsexpress.com is not your personal erotica site.

    By the way, you missed one-

    I really hope you don't think I take those oddiofile terms seriously!

    I think he tried to pimp them but they kept talking noise like a NS6, so as we now know, sometimes you have to cut a NS6 :eek:

    I'd suggest you start a new thread and edit your OP to include a link (or links) to test(s) of different drivers. In the OP of your new thread(s) include links to this one and all others. This is "probably" the least confusing method although many folks will cross-post in this and other threads regarding the various drivers. It'll take some diligence to keep your threads on track. Oh my... what have you gotten yourself into??:eek::D

    While I thoroughly enjoy your provocative one-word comments, I have no idea what you mean by this.

    The Aurasound NS6 sounds so whoreible, there's no way I can make it worse.

    The only question is, should I start a new thread for the NS6-255-8A?

    4 drivers have been baselined.


    Sample 3 has been cut.

    Part Express linked to this thread on their facebook page. Hey maybe they could send jbruner some free drivers so he can improve them with slits and document the work and improvements. I mean something like oh I don't know say a pair of Dayton Audio PM180-8 6-1/2" :D

    Shame the copper penny didn't do much. THIS guy used a short length of copper pipe (scroll down).
