So I recently hooked these up to my AudioBox iTwo with a couple of 1/4" TRS cables. When I listen to a song on them, the right speaker is nice and loud. On the left one, however, the sound is so quiet that you almost can't notice it. Both speakers are functioning properly, and I have the default I/O setup in Studio One 3 Artist. I'm not sure how to calibrate them since the video from PreSonus showed the E5 (I think), whereas the E4.5's are different. I'm not sure what to do.
