^ all eqauls..... SMELLY SPEAKER !

 

If you want I can just say that people are stupid and always turn their stereo's up to far when they don't have the power to go that loud and then they blow their speakers, up....

Hows that ? [img]tongue.gif[/img] </font>[/QUOTE]That's exactly what I was thinking [img]tongue.gif[/img]

 

Back to the original topic:

People that think there is one true BEST brand or product out there.

IE: What is best at SQ, pg or jl?

heh

 

i agree with tim all the way. I can vouch how for how clipping will blow a speaker and overpowering will not unless you exceed the drivers excursion or cooling capabilities. I ran 2 amps on a rfl and ran them into cliping and guess what VERY smelly speaker. This sub is capable of 2000 rms, and point is i ran four 1501d's on the sub far axceeding the subs rated wattage by about 4000 rms and did not blow the woofer. Ive found with good clean power subs can often take more power than their rated for especially in burps. Also you can murder most subs regardless of make and quality due to clipping i guess what im trying to say is. When you run an underpowered amp on a speaker the chances of clipping goes up greatly compared to having a bigger amp and leaving the gain down.
By the way you can definelty hear clipping no doubt about it. Im a hundred percent sure of it. No mistaking it when you drop from 152.5 to 146 on a touch of the deck and turning down the volumwe shoots you back up to 151 plus its definelty clipping. You can hear it cause it sounds like a dirrty buzzing noise and is all around gross to hear, quickly followed by smoke and the god awful smell of coil. [img]graemlins/thumb.gif[/img]
I think that helps explain somewhat, what i have expierienced with clipping and such.

 

^ all eqauls..... SMELLY SPEAKER ! </font>[/QUOTE]It was my understanding too that a clipped signal was aswell compared to the normal AC signal a subwoofer or speaker usually see's am i right Tim? just makin sure.... I read that bcae thing too and thought that was leftout, i assumed it was right too because i wasn't quite sure..... [img]smile.gif[/img]

 

Power ratings of subs are based on thermal, or physical limitations of the driver.exeeding either will reduce the life of the suspension or v/c.
under powering,and running into clipping will overheat and burn the v/c.
clipping will actually attempt to hold the speaker's cone at the excursion that the amplifier will produce EG:just like applying straight DC current
the lack of driver movement(which cools the v/c)
makes the v/c smoke.

 

Underpowering can NOT, will NOT EVER blow a sub. Period. Clipping will not either.

It's the extra power produced by clipping that could(if it exceeds the RMS of the coil)

Say you have a 500wrms sub.
You have an amp that does 300wrms. That amp driven into full clipping will be putting out a 600wrms square wave. It's the extra power that will burn the coil over time. You put the same amp on a 1000wrms sub, even that amp, fully clipped will never hurt it.

I find it a little strange that some people continue to support myths in a post created the dispell them [img]graemlins/dunno.gif[/img]

Anyway, back to the topic [img]smile.gif[/img] :
Myth: the RMS of a sub is a power requirement

Oh man dude, you just opened a can of worms.
