And below is the email I received from Loud Tech. Inc.:
I wouldnt recommend running the cabinet in a dual-mono configuration. The cabinets would be under powered by so much that you would likely send the cabinet a clipped signal.
While, it is still significantly under powered, you might want to connect the cabinets to the SVT4Pro in mono-bridge. Since the cabinets would be connected in parallel, the two 8 ohm cabinets would put a 4 ohm load on the amp. Make sure that you use a mono bridge cable that would be wired for +1, +2 at the end that terminates at the amp and for +1, -1 for the end that terminates at the cabinet. Keeping in mind that in mono-bridge you will still under powering the cabinets by 600 watts. At very low volume, you should have a clean signal, but because of being under powered by so much, when you boost your levels clipping may occur.
So am I up the creek on this? Significantly underpowering the two cabs?
I'm not even familiar with the "+1, -1, +2" mono-bridge cable. What kind of cable is that?
Very frustrating indeed.
