Fir filter/convolution problem Jriver, Rephase& Rew

[Korppi]

I have been driving active diy speaker setup:
Source--> Jriver --> convolution, crossovers 6h--> rme ufx--> amplifiers-->speakers

Crossovers are done with rephase and eq with the eq in the rephase

Convolution file is text .cfg form

This setup sounds good to me....

So then i just wanted to see what is the max out of my old Behringer truths b2031a's, so i decided to eq them flat. To get rid of that rising tweeter response. Took measurements with rew and imported them to rephase. Used the same linear phase eq in rephase as always...

Made two channel .cfg convolution file (Behringer left and right)

Imported it Jriver and started playing..

Sounds completely horrible! All the clarity is gone and its like dual mono but much worse. Soundstage gets really narrow to the center/middle of the speakers .

Problem is clearly in the convolution, because i tested it by importing the rew suggested eq correction (Hz,q gain) manually to the Jriver parametric equalizer and clarity came back and equing is working, makes the sound better than the factory set b2031a

Where is the problem?

Here is the .cfg file

Its easy to make mistake with the file so i made it 4 times just to be sure

Only thing in Jriver DSPstudio in use when i tested was "output format" was set to 2ch + convolution of course

I have noticed that using "volume levelling" and "adaptive volume" in Jriver DSPstudio makes sound quality much much worse but those were not on
