The CLA NX offers 3 different sets of speakers.
They are The cla10’s with sub, the main speakers and a boombox.
This gives you 3 different sound profiles already.
I find that both cla10’s with sub and the mains are pretty heavy on the low end in regard to without the plugin
It’s definitely something to get used to.
Fortunately the boombox speaker has a lack of low end on the other extreme end as reference.
I enjoyed the ambiance dial, it helps to get you more closer to the speaker or more to the back for a more diffuse sound, again this helps with referencing your mix.
Ans I really liked the sound of the ns10 with sub with the ambiance off on my dt990 headphones.
Although on speakers, it didn’t work at all, but that’s logical. So don’t forget to turn off the plugin while exporting.
I also find that using the headphone eq modelling really helps in getting a realistic pleasing sound, at least on the Beyerdynamic dt990s I used for testing
