Sh!t !!!! when i plug in my laptop i'm getting a massive low frequency hum .... not sure what thats about but it throw's huge wrench in my plans ....

[filmslayer]

PHEW !!! got that issue sussed for now . not sure if it is with my laptop or receiver but i changed HDMI inputs and all seems to be working now ...

this ribbon amazes me , was super hot yet still sounded pretty good . this is after a resistor change on the tweet . went from 1 to 2.2 ... going to 3.3 next ....

a lil bigger swing . went to 4ohm on the tweet and added 1ohm to the mids ... getting close ...

That's looking really good to start - interesting that the ribbon can sound so good even when it is a bit hot

i think it was just the change . it got forward quick ...

the latest change . 5ohm on tweet , 1.8ohm on the mid





this sounds really good .

Looking good!

A couple of suggestions if you're interested.

Your measurements don't seem to be changing much with the resistor changes. I would go back to the sim, and see what was supposed to happen, vs what did happen. On the mid, I would add the resistor after the x-over. I suspect that after the x-over will work better on the tweeter too. Sometimes a resistor in parallel with a driver is a good thing too, since it tends to level the impedance.

here is my sim as it's playing , keep in mind my files are all factory . i'm thinking i'm dealing with BSC and not trying to make huge changes . i'm open to to changes but like to do my padding before filter for ease .what would you suggest ? i can attach the Neo file if you want to play along .

I'm looking at your measurement in post 47 compared to post 50. I don't see much difference. There may be good reason for that though. Three ways take some trial and error, and your ears tell you as much as the measurements sometimes.

I'd love to play along.

let me see if i can do it . i believe i got all zipped already .

[filmslayer]

here's the frd , thet say me my zipped file is invalid .

[filmslayer]

i cant find the Z file in my documents when i try to attach a file but it in there when i open Xsim ..... i am not good with a computer ! but being a ribbon it is a flat 5 ohm line ...

i'l keep trying .

[filmslayer]

i will not be defeated !!!!! bwahahah

the rs225-8 and ds90 files i pulled from PE . heads up , don't buy that 89db on the 225 ..

[filmslayer]

my sim when i tune the 225 - 6db ...
