The four π-18 uses an 18" woofer (JBL 2241, 2242, Eminence Omega or Kilomax 18) in a 10ft3 cabinet tuned to 30Hz. The 12π is a 45x45x28" folded basshorn using a pair of 12" woofers. It has castor wheels so you can move it around pretty easily but it is large and heavy. You'll definitely want a trailer or truck with a ramp if you move them much.
