Rs180P/RS28F vs. small DC160 3 way

[filmslayer]

i'm kinda impressed . Famous Maker 3" raw driver near-field ...

[filmslayer]

with third order distortion ...

[NyxOne]

Whoa!!! Well behaved driver for the price! Looks like you have a winner! :D

yeah , not bad at all for an $8 driver ...

That driver looks nice, and smooth, but the 3rd order distortion looks off. Third order distortion measurements are not normally that smooth on drivers I've tested. I suspect that the distortion is lower than shown, and maybe you are measuring the noise floor. If you measure from a couple of feet away, and at a louder spl, I would expect the distortion will be lower over much of the frequency range.

that was the second measurement , first time thedust cap hit the mic ! that was as close as i could get !!! as you know i'm using Holm ???

rpb , i took a bunch of measurements today , i also have that driver at 3ft on design axis . i can go back and pull that up if ya like .

[filmslayer]

rpb , cuae you asked . 3ft on my design axis as loud as i felt comfortable testing,3rd order ...

made some changes last night , definitely think i'm on the right track ... however , all the measurements i took monday are still not being used . i really struggled yesterday with tracing and getting usable files , got frustrated and angry so i went back to the factory curves .... it sounds much better but there is still some work to be done ... measurement was taken in place not out in middle of room so take it for what it is , i just wanted to confirm what i was hearing .

[filmslayer]

God bless Josh Brunner ! talked to him yesterday and he knew of my frustration and aggravation so today he offered to trace and extract min phase for me ... making these changes now that i have my measurements ...

[Navy Guy]

Why are you trying to trace if you have measurements? Why not just export them?

can't do that with Holm and Xsim . AFAIK

[jhollander]

We can talk you through ARTA...

You can make an FRD file from HOLM measurements. It's covered in the guide.

good to know ! i will be checking that out . does it include phase as well ?

really close now ...
