Do These Speakers Require a Back Box?
Back boxes are not required because in-wall speakers use an infinite baffle design. This allows the speakers to work in various size spaces, like inside a wall. OSD Audio Speakers can adapt to a broad range of enclosure sizes and can be installed with or without an enclosure (with infinite baffle, the wall cavity becomes the enclosure). There is a tradeoff, however. Without a back box, sound may bleed to another room. This may or may not be issue but if you decide to build an enclosure, it needs to be at least 5 to 6 inches to accommodate the depth of the speaker. Also, it's not a bad idea to ad fiberfill inside the cavity, which can be purchased at any hardware store.

Contour Switches
The contour switches will let you tailor frequency response to your room arrangement. You won't find yourself wishing for more or less treble, midrange or bass output from one speaker just because you don't happen to sit right between them.
