Question about PreSonus Eris E3.5

Do you have bass? Yes, you do. There is a rotary control on the back to additionally boost or attenuate treble and bass. But of course the sound pressure on the bass is generally somewhat limited. It's only a 2-way system. And there is also no option for a subwoofer. I need these active speakers for good and preferably linear and undistorted monitoring and not so much to listen to music and let the bass "massage" me. As monitoring speakers they perform very well. Especially if you don't consider the low price.
