regulating a power signal from a 450W head

OneofFour	Date: April 21, 2006 @ 2:41 AM I'm looking into getting a 450W behringer bass head, but I want to get a 350W cab, (I might upgrade the cab later) is there any kind of electronic equipment that can limit the wattage output?
Alexsy	Date: April 27, 2006 @ 1:20 AM i cant help you solve your problem, but 450 watts seems like an immense, and probably not altogether practical, amount of power.
GeneHilbert	Date: April 27, 2006 @ 2:32 AM Actually 450watts for a bass amp is not that much.... and ideally you would like to have the two matched, or more speaker power rating than amp in a bass setup. I have run a 100 watt cabinet with an amp at 200watts @ 8ohms for years with no problem. I have also used that same amp with 1 - 150watt cabinet at 200watts @ 8ohms on occasion and 2 - 150watt cabinets at 300watts @ 4ohms on other occasions with no problems. However………. Pay attention - you can use this pair together providing the ohm loads match or the cabinet ohm load is higher and YOU DON’T CRANK UP THE AMP AS LOUD AS IT WILL GO and fry the speakers. Because you will……. if you do. If both cabinet and amp are rated at 8ohms, 4 ohms or 2ohms – you’ll be ok. As well if the amp is 4ohms and you run an 8ohm cabinet you are ok, as long as you stay above the ohm rating up to 16ohms on most amps, but read the specks – because all we can do is guess based on what you say. Just take it easy, or you’ll be replacing the speakers sooner than you think. If possible buy a matched pair, that will alleviate all uncertainty.

imemine	Date: April 30, 2006 @ 9:15 AM I’m sure that’s “peak power. No problem really. It’s distortion that blows speakers 9 out of 10 times. What I mean is clipping the signal of the amplifier causing a square wave rather than a sine wave (that distortion) When an amplifier is clipping it causes the speaker to stay longer in either an inward or outward position thus generating heat and poof----melted voice coil! That simple, watts are simply a gauge. FYI---speakers don’t have watts!
Snoogans775	Date: May 1, 2006 @ 1:26 AM yeah, that was a kind of simplistic way of saying the peak of the cab, thanks guys, I think I've got it handled now, I'm just gonna throw in for a 2X200W setup @ 4 ohms, it should be safe.
