Well, I have been thinking about ditchin the Hartke and moving to something else. I have a 4ohm Avatar B210 and a 4ohm SB112. I play mostly rock and some funk/disco, and play small/medium rooms and outdoors. My choices so far are: 1) Use my BDDI with a QSC PLX. Maybe the new PLX2 1104? 2) Eden WT550 used 3) SWR SM 500 used Any suggestions? My budget is probably around 600 - 700.
