So at practice last night I managed to blow one of the drivers on a 2x15 I was borrowing with my vintage SVT head. I believe it was an 8ohm cabinet and the driver was in rough shape to start with. Anywayz, the only other cabinet I could use was a very old Traynor 3x12 cabinet which was rated at 2.7 ohms. This makes sense for 3 drivers but my question is what will the SVT think it is? The old SVTs automatically switch to the 2 ohm tap when both speaker jacks are in use, they're expecting to see a 4 ohm load on each jack. What happens when you plug one 2.7 ohm load into one jack? Using one jack means the amp is running off the 4 ohm tap right? It sounded good and everything, actually giving me more volume at lower settings than ever before but was I putting the amp in danger by doing this?
