If you are dumb enough to put DC on a driver....go for it. I would never put a battery on a speaker. That's stupid.

Touching battery leads to a driver is a common industry practice to verify the pole markings. It would be stupid to accept those markings without verification.
And no, we're not talking car batteries here. Give me a break.

Actually, using a 9v battery is a very common way to quickly verify + and - terminals on a speaker. Ive been in the pro audio industry for 20 years and people have been doing this (for good reason) commonly all along.
Why do you need to verify pole markings? Your high end manufacturers can't do that right? What hard stuff are they screwing up.
It is not an industry accepted practice. I know too many people in recone shops to know the truth.
You can put a 9volt battery on a decent loudspeaker and it wont
hurt it whatsoever
To think putting a small DC voltage on a loudspeaker will damage
it is dumb
I wouldnt recomend a DC voltage like that on a tweeter or a compression
driver
Your talking a fraction of xmax from a small DC battery on a woofer
or mid driver
ff
Do it on a new speaker from any of the major manufacturers and see if your warranty is still valid.
Stupid because.....?If 1.5V DC damages a woofer, the woofer must be a real P-O-S.
Guy's, I implore you...do not blow your woofers using
a whopping 1.5V D cell battery :)

9V has been proven to burn some coils. A little DC may not do the thing in right away. It may contribute to a future failure. This applies to low W drivers mainly. DC is a speakers enemy.
