[QUOTE="Don Boomer, post: 67706, member: 633"] Re: Peavey SP4 speakers nackered, new baskets or magnets? If you've got mechanical damage you should be able to remove the magnet from the basket on a Peavey BW and give it a visual examination. I'm not sure from your explanation what your gain structure is. What is important is how hard you are driving the power amp and how low the frequency can go. Do you have the limiters engaged on the power amps? HPF? As far as power handling there are a number of things called SP4s all with different power handling so you need to make certain which you are looking at. Also power handling is probably a bit lower when you connect to the drivers without going through the internal passive crossover as there is likely a dB of loss in it. I know of one Peavey SP speaker system that although rated at 500W the LF driver never sees 300W delivered to it. In any event I don't think simple overpowering is your problem. You probably have drivers that were already damaged by over excursion. If they were thermally damaged chances are they would simply be dead. [/QUOTE]
