good answer dukk,...dont like # one because of the odd order harmonics created by third order boxes but they due tend to make those bottom octaves hit hard... and for the amount of trial and error to actually get the box tuned to the car.. sealed everytime.. that said... speakers are just mechanical devices that move back and forth with an ac input over a magnet creating a negative and postive field.. so if the input is not perfect the voicecoil does erratic things. now since no music is perfect except through the actual instrement, the best we can hope from a speaker is decent performance. compound that with a clipped signal which transforms the waveform from smooth and linear to square, which eats voice coils and rips surrounds, and spiders, to heavy distrotion which moves the voice coil into a more non linear range of motion. remember its trying to due multipul frequencies at the same time... its a miricle that they work at all in my opinion! your ears our your best defence against speaker meltdown... the speaker will tell you when its stressed, usually long befor it blows.

 

I don't really crank them because I know better, There's no way I want to blow these speakers because of the price and I cannot find these around here.

I am guessing I'd have to abuse them for awhile before I blow them to pieces, But I'd like to keep them for many years so I should play it safe...

Had to order them from MR2NR (Good guy to deal with).

 

You are a funny guy. Why does distortion move the coil non linearly? More importantly...how?

 

This should be interesting...

 

If it's a dual VC, maybe the they aren't aligned. lol!

 

my bad folks on my explantion.... on distortion to speakers.. as i stated distortion is the death of a speaker, but not on the input side but on the output side.. sorry about that.... the transducer just plays the ac that it recieves from an amp.. thats it.. distored,clipped, loud or soft... if you hear the speaker distort turn it down its a sign of problems.. now if the amps signal is clipped or distored by driving the amp to hard it will send a more powerfull ac signal to the transducer thus surpassing its power handling and creating distortion.. sorry for my mistake. i realized it once it was pointed out.. just wanted to make ammends for my blunder.

 

^I think there is another mistake.

There is a distinction to be made between clipping and distortion. You use them interchangeably but they are different.

Distortion, no matter the amount cannot harm the speaker. Distortion is a measure of "differences" between the input and output. The subwoofer doesn't care how accurate the signal that comes in and it certainly can't harm it.

Clipping on the other hand is when the amp outputs a square wave or DC and this is bad for a couple of reason. It heats up the coils faster because the speaker stops moving while receiving DC an thus cools less. Also when an amplifier is clipping it can be out-putting about twice or more it's regular power. This can cause mechanical or thermal failure.

Of course if the driver can dissipate the heat generated by the clipping and that the clipped power isn't enough to push it past it's physical limits then the only consequence is that it will sound bad.

 

i used to work at futureshop in the car audio section, most customers dont know anything, cant blame the sales guys for trying to upsell stuff. i've seen over and over again how sales guys would sell customers stuff they didnt even need.

 

So this might take it a bit off topic...but I have a set of focal A1'S ,THINK their rated for 60rms...their not in yet but i have a rockford..p2.2oo..dual ch ..Now as a noob i was thinking that i could just turn down the gain to the spkrs...My original plan was to get a smaller amp.but was told this was the way to go..really dont want to blow these things..is my amp too big,was the shop full of crapola..after this read IDK

Look there, I will update it hopefully today and it should answer your questions... I had totally forgotten about it.
