Any one know how to fix my speakers?
AbyssDJ:
most likely because your hifi isnt powerful enough, dew. the first thing you will get is signal distortion in the form of a square waveform, which has the same effect on a speaker as hitting it with a hammer.
many people in the PA and particularly the mobile disco world believe that if they have an amp thats not quite as powerful as the speakers are rated, they will be fine for life ;) quite the opposite... your amp should actually have a higher rated power than the speakers.

Standard systems I put into clubs were 1.5Kw per channel, 9 channels and 1.1Kw Speakers in all but 2 clubs. this is also 1.5Kw of REAL power not 'Car Stereo' power
Tiny little 2u rackmount Toa Crown amps and mahoosive Cerwin Vega speakers, you should see what happens when speakers fail at that level. JBL Epicentre and Bass Setups in some wasnt far off a 90 in size (and weight)
Its possible to vapourise an amp because it cant deal with the draw from the speakers, especially inf the imnpeadance isnt matched. I wont go into the details but speakers are known as reactive loads as they arent just consumers of electrical current but can produce their own. There areso many pitfalls that people arent aware of if you want a perfect setup, for instance, just having uneaqual speaker cables, especially in a surround system, is a common screw up. Or having the polarity reversed.

thats the thing though isnt it? so many things to be overlooked, especially in an RMS power situation like PA systems. and the biggest of them all is people that dont bother to/dont know about setting the gain structure!!!! simple way to turn a top of the world funktion-one system into a harsh sounding mess.
most of the stuff we sell to clients now is active, usually from dB Technologies and RCF. some extremely nice systems available from both of them... particularly the dB Fiftyline and RCF 4Pro gear. wouldnt turn down a sale for the new line arrays though :D
