ID12v3....they wired the sub wrong?

[Mission72 10+ year member]

Ive seen professional subwoofer makers use 9V batteries so id say its plenty safe.Please dont argue.

Sure you have....You also said 4 posts earlier that you knew 1.5V wouldnt work...I am actually looking for a new set of subs, let me know who these professional sub builders are so I know which ones to avoid.

a 9 volt battery will not hurt a sub unless it has a thermal rating of well under 100 watts.

9 volts into 4 ohms is 20.25 watts.

9 volts into 2 ohms is 40.5 watts

1.5 volt into 4 ohms is 0.56 watts

1.5 bolt into 2 ohm is 1.25 watts

I have alse seen some very smart people say a 9volt is fine on any speaker. Also you only touch it for a second so ther eis no more stress then a note being played.

I'm not going to disagree, I was just trying to make a point that 1.5 is probably safer. The other guy was trying to take credit because he knew that a AA would not work when in fact it works fine.

.56 watts (1.5v) is plenty enough to make a speaker jump for polarity checks. That was the point which I was trying to make.

i never said it woudlnt move it.

I was more posting it since you said you would avoid a company that uses a 9volt battery //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

It is easier to see on bigger low sensitviity drivers with a 9volt. I use both //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

I prefer to use the wall socket when i test for polarity, works just fine.

No biggie...It is my OPINION that I feel it is safer to use 1.5 volt than 9v. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

It is a FACT that 1.5v can be used to check polarity.

I've actually done that. Yes it worked fine when the smoke cleared.

 

[Darkstarling 10+ year member]

you guys must be bored to claim that a 9v battery could ever hurt a speaker when testing for polarity. You can put one on your tounge and does it make your speaker coil smoke???

Using a 9V battery will show the cone actually moving. Which makes it much eaiser to check vs a AA battery.

Just because im right doesnt mean you have to argue

I agree with this method.
