Xover to filter woofer SB 23NRSX45-8

[merlin el mago]

Not a big difference SS 15uF vs 10uF

 

[GDO]

For me it's better, might even atenuate somewhat the tweeter...🙄

Still with BR?

 

[merlin el mago]

SS 10uF BR port closed.

 

[GDO]

SS 10uF BR port closed.

Don't you have any coil bigger than 4.7mh and smaller than 8.2mh in your alibaba cove?😀

 

[merlin el mago]

SS 10uF BR closed

Yes 6.8mH

 

[merlin el mago]

6.8mH green vs 4.7mH yellow

Tweeter not attenuated.

Yes still BR.

 

[GDO]

For me the last curve obviously looks better, the 10uF no BR stuff, but...

We have changed many things lately... Sound wise what's your feeling? For better or worse?🙄

Me deaf...😀

 

[merlin el mago]

I can't listen today, tomorrow I will listen and let you know.

 

[merlin el mago]

Could I flatten the SBA peak as does Troelsgravessen using one LCR?

Better to listen first, only painting curves a hopeless game...

The other big problem is the 100-200Hz valley.

Yes it's better the SS with 15uF vs 20uF but no big difference 15uF vs 10uF.

Think so too and that's why i suggest lowering the xover point in order to boost that somewhat.

From the beginning i am trying to help your xover eqs your system in a usefull way, not the classical text book xovers do...

TG manages to get this done? Wow...😱

Have I to increase the 6.8mH coil for the SBA?

The driver parameters for lspCAD are only impedance *txt format & SPL *txt format?

What's the matter with you two? You have turned a 3 hour job into a loudspeaker nightmare project.
