[PD] [OT] Bass driver unit

[Derek Holzer]

Search for "bass shaker" or "bass driver". Aura is one of the main brand 
names for these. These are bass transducers designed for home theaters 
and car audio systems. The idea is to put them in the seat and the bass 
literally kicks you in the ass. I used them to resonate a huge structure 
of construction scaffolding once. They are usually approx EUR 25.

Difference between these and solenoids is that you drive these directly 
with audio, meaning you need a multichannel soundcard to drive several. 
Solenoids get driven by DC voltage via a transistor (which in Roman's 
case is driven by a microconotroller/Arduino), so the cost per channel 
is much lower.
