Can you change speakers when you have DSP?

What is the range of the Ladedruck? 
I just looked at this pic

Eric,

The range is 0.4 to 0.8 overboost and that means 300-360 PS. (depending on the outside temp)

Hannes,

I´ll usually listen to the enginemusig but my girlfriend doesn´t like that as much as i do...
Do you have some recommendations regarding speakers, because normally you use filters but i guess BMW´s speakerfilters is in the DSP, correct?

Thanks again,
