Exactly how much power does a large subwoofer motor have?

Could you make an air pump or turn a small crank?

subs do not produce power.

Subwoofers move because power is being applied to them....the term "motor" is used loosely, subwoofer do not make power.

Power meaning force

So no physical force is created by the motor?

If no physical force is created by the motor then how does the cone move?

No power is produced, an amplifier powers a subwoofer....force and work are being produced though.

what are you trying to do with a subwoofer???

Just wondering how much physical force is generated by say a 18"xxx motor playing a 50hz tone at 1000watts?

1 horsepower = 768 watts

Take the highest constant power (watts) you need to move a driver to xmax, divide by efficiency, and you'll get how much power is being used to physically move the cone of the driver. Divide by 768 to get the horsepower the motor is capable of producing when moved to xmax by some other means.

The motor in a driver is a motor. It also works both ways, just like the little car motors you spun to light up a lightbulb in science class. I remember as a demonstration a dealer put two woofers (MA HK 15s) in a sealed box with shared airspace. He then powered one til both were near xmax and had some numb-nuts know-it-all put the leads attached to the other driver on his tongue. Oh yeah, they make electricity. =) That bastard yelped like he'd peed on the third rail.
