Too little power blows speakers?

[01 S 10 10+ year member]

It's too vague of a statement, there are many variables that can make it be interpreted as true or false.

but in the end, its FALSE! (of course assuming its a clean signal, etc, etc)

If your sub can take 2000watts rms, you can give it prolly about 500watts of clipped signal all day long with no ill effects
Its just when people get these lower end subs and get it close to the rms and still clip it, ouch ouch happens

its also harder to judge cause alot of speakers arent rated 100% accurately.. some way overrated.. some way underrated and everything in between

did you ever think it might be beneficial to dealerships to float this rumor so that they can sell a little bit more expensive amplifier.

I still don't understand where this idea came from; it never made sense to me. With this theory it's basically bad for your speakers when they are sitting still and receiving no power.

Booooooooooo you. I found an error on a popular site and I'm proud of it.

You know it man.

remember guys, BLAST your speakers and subs constantly so they dont blow up from too little power at lower volumes!!!!

The problem with these arguments is that douchebags take them to the polar opposite extreme with statements like:

"I guess NO POWER will kill them as well"

or

"If you have a 1000watt sub and a 30watt amp you can never blow the sub, never"

Duh. Of course a 30 watt amp has almost NO chance of blowing a 1000watt sub and of course NO power will not hurt them either. Now some noob reads this and clips his 70 watt amp into his 80 watt components and 6 months later wonders why they burned up because according the people above too little power doesn't hurt speakers. Ever.

Like the bcae site explains

If it we're true than every time you turned your radio down your subs would blow

Noobix cube... You're not under powering the speaker anymore. Clipping increases the area under the curve (=power transferred)

Therefore your 70w amp is NOT producing 70w, more like 100+. Therefore you are OVER powering the speaker, and burning the voice coil.

Exactly!!!! Which is why I mentioned "clipped." But people keep saying under powering and 90% of the people who read this think as long as the amp is rated less than the speakers they are safe. You uber nerd scientist type people are basing your arguments on technicalities like a lawyer. Kinda like saying jumping off a building won't kill you, hitting the pavement kills you. When in reality if you never jumped you would have never hit the pavement.

And before someone brings up the guitar amplifier example just let it be known they sell replacement speakers for a reason. They DO burn up, eventually.

ignoring mechanical issues, heat destroys a speaker which is merely a function of current and time.

This statment lays it out pretty strait... So if someone wants to act like a relativley small increase in output from driving an amp into distortion can damage a driver then they better consider that listening to the equipment for a little longer then normal will too...

It's not a technicality, its fact. Under powering is exactly that. If, at the end of all setting changes, the power transferred through a voice coil is less than what it can properly handle, it will not hurt the driver. Period.

Its not our fault if some retard runs out and buys a 600w RMS mono amp for his 650w sub and cranks the gain. Its his fault for not understanding the amplifier and how it works.
