since I have deactivated the Bose since the DSP shutdown I do not want to include you before what this brings:
1. The heights and upper middles are definitely cleaner, clearer and the stereo perspective is clearly better represented in the room.
2. Bass is now in abundance, I am standing on -5 at the moment, the bass has not changed in itself, only you can hear that the subwoofers do not come completely crisp. (Was before that only one hears it more clearly now)
3. The instruments and voices are nicely detached from the speakers and in classical music the orchestra is now also "visible"!
4. ==References====External links== electronic music (Schiller, Bliss, Nightmare on Wax etc.) the effects of the individual sound worlds are placed more clearly in the space.... but not as perfect as home...

5. Drum ́n bass gets a little spongy due to the not very exact woofer. (If it was like that before, only in the porridge went down)
6. The low bass of the woofer reaches quite far down, as I said not perfectly clean but up to 25 Hz at minus 2 dB (according to the measuring microphone) are inside and that is respectable!
7. Now you can also distinguish a well-recorded CD from a poorly recorded CD in the car! You can hear it clearly!
Conclusion:
Who always wanted to hear the Bose as it was praised by HiFi magazines (1997/1998) should not hesitate and try it yourself!!!
Simply turn off the Bose via VAG-Com on the radio, the bass control down the heights a bit and enjoy!!

I am grateful for your hearing impressions and experiences!!
