Pyro Board (2d Rubens Tube) (Speakers + propane = cool fire)

Hey guys,

This video has gotten a lot of attention the last 3 days (originally from Gizmodo):

My department has a standard PVC Rubens tube for demos to k-12 kids, but this is another level. Looks sweet. I think it'd be a badass grill and/or built in HT fireplace.

Preliminary idea before I start carving on my good equipment, is to tap a hole for a propane feed into the bottom of my promedia 2.1 subwoofer, and flow enough propane to light the port.

Anyone piddled around with flaming subwoofer ports before?

I expect the pressure fluctuations, i.e. port chuffing, to produce the kind of dancing flame height seen above; think that a good kick drum might put the flame out though. Might need a pilot light of some sort...
