I'm currently using my LMII with an 8 ohm Dr Bass 1260 (1 12, 1 6, tweeter). I need to expand the rig to play larger shows, and am wondering if the Markbass will be sufficient if I am looking to add a 1 15, 2 12, or 4 10 underneath the Dr Bass. It will be running 500 W @ 4 ohms if I add an 8 ohm cabinet. If not, what would you recommend? Thanks in advance!
