[QUOTE="Brian jojade, post: 67608, member: 211"] Re: Peavey SP4 speakers nackered, new baskets or magnets? My experience with Peavey drivers is that they typically will sound like absolute hell way before they burn up from overpowering them. However, you can cause over excursion with the right frequencies and power applied. The Peavey SP4 has a power rating of 1000 watts continuous, 2000 watts program, and 4000 watts peak. However, that's the full cabinet, operating in full range. If you're filtering out the low end and still driving it with that much power, you're asking the top driver to work harder than the other which means the power rating available is going to be lower. Roughly speaking, if the 2 drivers together can handle 1000 watts, but you're sending frequencies to only one of those drivers, it's only going to be capable of 500 watts. Under normal conditions, an RMX1450 should be just fine on that speaker. However, if you're running heavily compressed music, you're asking for trouble. My general rule of thumb is when matching amps to speakers, if the term DJ ever comes up, the amps are never sized more than the continuous rating of the speakers they are going to be attached to.
