These things came with detailed setup instructions -produced really nice tight musical bass.Have heard them mated up with things like stacked Quads and the combo worked! Not sure if they would be particularly appropriate or effective for dinosaur footfalls - but will blend into a music system just fine.
You really do need the controller/X-over for these speakers since they are mono and dipole radiators - the controller is a necessity.
