Enclosure info for the Cyclone:
Many experiments have concluded that the best box is a sealed box that shows the Cyclone 2.0 to 2.5 cu.ft. Remember that the Cyclone displaces .5 cu.ft. by itself. If the Cyclone will be inside the box, make it 2.5 to 3.0 cu.ft. If the motor is out of the box, make it 2.0 to 2.5 cu.ft. For rock, rap, or most other popular music, use the smaller size box. For the ultimate in smoothness and transient response, use the larger size box. You can mount the Cyclone at any angle either in the box or with the motor exposed. Build the box as strong as possible using MDF or better material. Line the box with a few inches of polyfil or other acoustical material
