I need some professional advice on how to protect my Bag End 2x10 from being damaged again. Before I go any further, replacing my amp and cabinet are not an option. I am very pleased with the sound of both and cannot afford to buy more equipment. The D10BX-D (2x10) speaker is rated at 400W continuous at 4ohms. I also have a Mesa Boogie M-Pulse 600 amp that I am thrilled with (sound/features/great compressor/etc). It's power output is 600 watts into 4ohms. During a very loud concert I damaged one of the speakers. I will not use if for that venue again, but after I replace one or both speakers I want to ensure that the amp does not spike into the danger zone again. I will use the compressor's threshold setting and keep the volume reasonable but - Is there a devise that limits the power output? I do not want to color the sound, only protect the speakers from incidental power amp surges.
