I've got a curious query. I used to run a GK1001rbii into 2 cabs, a older Trace 1048H rated at 300w RMS and a Behringer 1x15 which was rated at a supposed 500w. I ran this rig nicely for about 2 years until the Behringer cab popped. At this point it was 6 years old so I figured that was a rather good run for a cheap Bogginger. Up to this point I was obviously getting 4ohm out of my head which was affording me the full 700w of GK grunt. Due to this I never turned either of my gain or my master past 9 oclock. Due to the fact I'm poor I couldn't afford to get a new cab to replace the Behringer so I decided to carry on with the Trace on its own. I was of course aware that the Trace wasn't designed to cop the force of the GK head, even if it was only getting like 350w of the GK's total load. I was totally expecting to run the cab into the ground before too long. A year later and it's still going strong. Last Friday I had a show in a long boomy room that required me to actually dime my GK for the first time. I pushed it super hard and hammered in with a down tuned bass, at the amp's maximum master at 8ohm. Awesome response from the cab ensued. I know this might seem like a clandestine advertisement for Trace Elliot, or a bit of a brag, but I legitimately just want to know the reason why this low rated cabinet seems to be able to survive being flogged mercilessly week after week. I've heard that a good rule of thumb is that you should have 2x the wattage rating of Cab vs the wattage of your head to be able to call yourself semi-safe. But 350 into 300 doesn't seem to pose a problem. Does anyone know why I'm getting away with this?
