Just like a water hose If you're working in your trunk and want to stop your subs from getting power for a sec, just kink the wire and it'll stop current flow

you owe me a new keyboard dude.........i just spit a can of coke all over it.....

GlassWolf wrote:I agree with Jon for the most part, although I have seen a number of subs damaged by clipping without going beyond the thermal or mech limits of the speaker. This mainly happens when the sub loses linearity with a square wave input, and the coil gets shredded along the inside of the magnet.

I'd halfway consider that a mechanical limit, but one that's not taken into consideration. I forgot to mention that one. When I think of some of the folklore I've seen, some people people treat clipping like the square wave is going to make the VC do some crazy stuff like rock sideways or something

Which, pushing the driver past linearity can cause rocking, just not with a decent BL strength. It's also important to note that the power rating from manufacturers fluctuates a LOT, better to be safe than sorry.

It actually takes a lot to blow a subwoofer. If it sounds like shit, turn it down. If it starts to smell, turn it down. Now..if you're riding around town playing 20hz test tones all day..well yea..there's a good chance the sub isn't gunna like it. I still haven't damaged a speaker, and I don't understand how so many do. I was giving my SE (rated for 600w RMS) 800W RMS off a Viper D1200.1 all day long. This was with the gain 3/4 tilt all day, every day. Still, probably the best sounding subwoofer I've heard. Never bottomed out, never got stinky. Was it recieving a clipped signal? Probably, but you can pretty much tell when a sub is playing within it's limits, or being overdriven. That's just my experience with speakers. Nothing real scientific. Mostly common sense. Some will probably disagree with me.

good points. I was thinking mechanical limits by way of exceeding Xmech, specifically. In regards to the Bl, most of the ones I saw killed this way were older subs.. old Orion HCCA and XTR series, JL W0 subs, etc.. smaller motors.. not nearly what we have on the higher performance subs today.

Polypropelene surround speakers have a sturdy cone.

That is the main reason that I buy those polypropelene surround speakers...cause their cone is sturdy....
