In-Wall Loudspeaker Installation Guide
6. The speaker assembly is then inserted into the hole in the bracket and attaches to the bracket and (dry)wall via six plastic mount-
ing clamps (dog-legs) on the back of the speaker assembly that will swivel out 90˚ and lower to “sandwich” the drywall (and mounting
bracket) when you start to tighten the six mounting screws (fig.6). Begin this phase by being sure the dog-legs are rotated sideways
(like the speaker came packed) so that the body of the speaker assembly can slide through the mounting bracket. Exercise caution not
to damage the drivers themselves.
Note: For improved speaker performance, consider using NHT IWF – In-Wall Acoustic Foam. IWF is sold in a pair pack and is only suit-
able in 2” x 4” studded walls. Available on nhthifi.com.
7. Begin to tighten the screws that at first rotate the dog-legs out 90˚ and then start to move downwards to clamp the wall (or ceiling)
and bracket. Tighten the screws carefully but snugly, making sure to not over tighten, as this may compromise the fit of the speaker
assembly. The use of power screwdrivers is not recommended but if you must, set the toque ratchet setting at its least resistive position
and the speed very low. The speaker frame lip should rest flush and seal against the wall (ceiling).
8. Once all the screws are snug and speaker secure, install the grill. It uses magnets to attach to the speaker. You will notice a gauzy-
white cloth on the speaker side of the grill. It’s called “scrim cloth” and helps hide the speaker’s silhouette from showing through the
grill. Do not remove this scrim under penalty of law!
