Im thinking about selling my Genz-Benz 6.0-12T combo and STL-12T extension cabinet and purchasing two Genz-Benz STL-2-210T extension cabinets and a Genz-Benz ShuttleMAX 12.2 head to power them. My thinking is I can run each 2x10 cab with the independent power amps in the ShuttleMAX 12.2 so each cab is getting 375 watts at 8ohms (750 watts total running both cabs). If I go with the ShuttleMAX 6.0 I would only be getting 600 watts. If I stick with the regular Shuttle 6.0 or 6.2 Im still at only 600 watts total running those two cabs. If I went with the ShuttleMAX 9.2 I think I would have too much power for the two STL-2-210T cabs as they are rated at 400 watts each and the ShuttleMAX 9.2 puts out 900 watts with a total 4ohm load. Not sure if running a 900 watt amp into two cabinets that are rated at 400 watts each could cause damage. I like the idea of going with the ShuttleMAX series because of the additional EQ the amp has. Just wondering if anyone has used the ShuttleMAX 12 series with two STL-210T extension cabs and what you thought about it. Also if anyone has any general comments on the proposed setup Im thinking about I would welcome comments before I make a big purchase and find out later I didnt think everything through and this is not a good set up for some reason.
