Underpowering a speaker is likely to damage the voice coil due to the excess heat created by distortion. This distortion, called clipping, is created when the amp is not able to supply the power demand when the volume is turned up. If you turn the volume up very high without the power to back it up, you'll end up clipping the signal coming out of the amp. The speaker will try to reproduce this clipped signal, and if played under these circumstances for any length of time, the speaker will not last very long.
There is a mis-conception that if you're not giving the speaker as much power as it can handle you won't blow it, but that simply is not the case. The only way to really address this problem is to replace your speaker for one with a lower power rating, and a higher SPL rating, or replace your amp with one that better matches the speaker's power handling capability. An alternative to replacing the equipment is to simply keep your volume turned down!
right bro, underpowering a speaker is fine. turn down the volume and what happens? power supplied goes down. the gains are to set when peak power is supposed to come in related to volume.
its the dumbass people who set the gains high and underpower a driver, usually woofers. i underpowered my old pair or 12s and didnt have a problem, because i set the gains according. theres only tw ways to blow a speaker, thermal and physical. over heat the VC and ur ****ed. physical is self explanitory. clipping will over heat the voice coil because it drives the amp to push more power into the sub then it can handle. its dirty power and its a square wave pattern.
Work Harder! Millions on welfare, disability and free govt. programs depend on YOU!!
thats the dumbest thing,"dont under power a speaker its bad" its the idiots that try to cheap out on amps and find it isnt loud enough and crank the gain(or volume on the amp in their view)
Barrman is obviously referring to the situation in which underpowering IS bad. Because whether any of you are capable of admitting scientific fact or not, if you underpower a speaker/sub you CAN damage it. Just because Barrman didn't take the time to clarify it in "moron-friendly English" doesn't mean he doesn't understand the concept of underpowering in relations to volume and/or gains.
Sony doesn't suck: i haven't had any problems with my sony at all and i have the same one he blew for a year now...if he would've gotten JL Audio, Infinity, or an Eclipse Titanium sub it wouldn't have mattered; it was user error. I mean speakers don't just decide to blow themselves up
