Ok, so all 4 are going back. I so wanted to keep a pair of these, but it's not happening.
PE will take them back and refund me. I have to take care of shipping as these are not "defective", so some other poor guy is going to end up with these exact drivers.
I believe, from what I have read, that 10%-15% variation from stated T/S is concidered "normal', obvious far less is expected.
I am suprised thay do not have some sort of AQL set up when recieveing drivers, or agreements that if they het stuck with drivers like these they can ship them back.
Not to beat a dead horse, but I did try out Arta and the distortion makes a bit more sense here.
The 369 driver:
The 482 driver:
The 182 driver:
The 164 driver:
I think the last two drivers have a better distortion profile than the first two. They would be strictly mid range, crossing over high (over 500 and then to a tweeter around 3-4k), definitely not a full range as I wanted.
Ani - there's no question your measurement process is valid. I'm sorry you had to go through this BS. You shouldn't have to pay for anything in this one. Straight up bullshit that PE is making you pay to ship them back. We should copy this thread and send it straight to Tang Band.
There have been many threads on driver parm discrepancies, but think about all those guys who don't measure drivers before they embark on that DIY project.

It is pretty scary. Sims are great to ballpark things, but testing the drivers is critical.too easy to completly miss and end up fooling onself.

Oh snap!!! I thought all those countless on-axis, purely simmed from manufacturers' curves designed crossovers that always use a Zobel on the woofer and an Lpad on the tweeter were the bomb?
I was lucky when I started, now everything gets measured and remeasure.
You would actually be surprised at how it likely was not luck.
It has been proven time and time again (Toole, Dickenson, Holland, and on) that between the room and our ear the amount of averaging that goes on is scary. We really only hear at about 1/6th, maybe once "trained" 1/12th octave resolution, fading to 1/3rd at the deepest frequencies.
Simming with MFG's specs will get someone "close enough" to have a speaker that to someone who only knows the big box store stuff likely sounds pretty darn good.
Little do they know what *can* be had by designing a speaker properly. I akin the difference to me getting behind the wheel of a F1 car. Man, I'm sure I could make it move, even drive it quick, but put a pro in another car next to me and I will get lapped... And lapped, and lapped.

The fountek drivers exhibit much tighter tolerance to each other, both in FR and Distortion
