It is better to add extra channels of amplification in combination with additional speakers. 4 - TRYING TO COVER AN OUTDOOR GIG WITH YOUR INDOOR SYSTEM Outdoor gigs require at least 12 dB (16X power) more sound output than indoors, and as much as 20 dB (100X power!) to really do it right. 5 - EXCESSIVE EQ The classic "smile" EQ curve is actually smiling at your speakers imminent demise! Keep in mind that EQs are best used for cutting, not boosting the signal. Need more highs? Reduce the bass...Need more lows? Reduce highs. 6 - NOT ENOUGH AMPLIFIER HEADROOM Too little power, and amplifier clipping becomes the norm. Use Amplifiers typically twice the IEC RMS power of the speakers. Big Amp = Less speaker burnout...... not the other way round. 7 - SUDDEN TRANSIENTS WHILE SPEAKERS ARE HOT Turn-off thumps, plugging/unplugging mics, etc. 8 - USING LOW QUALITY OR WRONGLY MATCHED PASSIVE CROSSOVERS Use crossovers which are suited to your speakers, specially check impedance (using 4 ohms speakers on an 8 ohms crossover, will give weird results) and wattage. 9 - CLIPPING THE SIGNAL BEFORE IT GETS TO Improper mixer gain distribution, line signal too hot, etc. 10 - KEEP USING YOUR SPEAKERS AFTER DAMAGING THEM And failing to have the crossover parts checked for damage after abusing the speaker system that way! Let your ears be your guide. If you hear distortion from any clean inputs, damage has likely occurred. -->
