Hi All, I have a Markbass LM2/NY604 rig I absolutely adore. I had high hopes for using it in my new bluegrass gig. I played a Carvin Cobalt ABG with O-port at bar gig volume. When I would "thump" the strings percussively between the 1/5, my speakers started popping! I'm curious if these small speakers just don't have the xmax for the piezo subsonic "boom", and I should look at a different cab for this gig, or if some buffer such as an fdeck or a higher input impedance preamp could help? Any recommendations are greatly appreciated! I hope I haven't ruined my cab!
