just out of curiousity, will blasting music often damage speakers? my brother blasts his music all the time on his speakers and now they're having some problems. blasting music on the JBL's is awesome, but will it damage it?

yesterday i made it play so loud it moved by itself from all the vibration.

freakin awesome.

It depends on the wattage rating of the speakers and amp. I blew my parents speakers out of their combo stereo/TV once when I hooked up my JVC receiver to them. The speakers couldn't handle the JVC's wattage. She hit a base note, went POP and blew the cones right out of the speakers!

Yes, speakers have a wire coil imbeded in paper or fabric. As a amplified signal fluxuates in the wire coil it adjustes the distance between the coil and the magnet. This moves air in vibrations which travels to your ear and vibrates your ear drum. The more amperage (volume) you apply the more the speakers move and the faster they wear out.

If you get yourself a analog or digital sound meter you can record the sound at difference distances.

Usually the more wattage, the higher the volume, the closure to the speakers and the higher decibels (dB).

A human can only handle a certain dB range for so long before ear damage occurs.

dB/hours

80/32
85/16
90/8
95/4
100/2
105/1
110/.5
115/.25 Emergency siren
120/.125 Rock concert/Airplane overhead
125/.063 Serious damage occurs
130/.031

Average conversation is 65 db, toilet flushing 90 db.

PowerMac G5 60 db, whisper 20-30 db

eMac 75 db

My tolerance is less than 60 db continous, anymore it's stressful.
