Best way to destroy a Subwoofer

boxcustom · 16th May 2008, 03:37 PM

I would like to destroy a subwoofer. 400 watt rms, 3 inch dual 2 ohm voice coil. I need to keep the woofer intact with no visible damage. I just want to destroy one or more of the voice coils. My plan is to connect the voice coil (s) to 110 volt ac. Easy. Just listen to the 60 hz tone until it fails. My other option is to connect the coils up to a 12 voit deep cycle battery with 800 CCA's. What do you think?

Get youself an arc welder and connect the ground to the negitive and the stick clamp to the positive.

WHAT FUN!!!!!

DC wouldn't be as likely to cause damage to the spider.

People do this to try to get woofers exchanged under warranty but many manufacturers won't warranty woofers with open coils.

Would just clipping the lead wires not be an option?

110 VAC @ 8 ohms = 1500 Watts
Better go to a 220 Volt country and try there! 6 KW!

tape a couple of heavy lead fishing weights underneath the cone, to one side and play a low tone... the weights should cause the coil to rub on one side and eventually fail....do it out of the box.

What brand of sub is it?

The big question is WHY????

Bring it to Australia, 240v 50hz 120a = 28,800w....
