INSTALLATION

RBH in-wall subwoofers have been designed to make installation as easy as possible. Upon opening the box you will notice that the retrofit nylon mounting bracket is attached to the subwoofer.

To install, slide the top of the black pinch ring into the drywall cutout opening so the subwoofer bezel is on the outside of the drywall and the nylon retrofit bracket is on the inside. Slide the bottom of the subwoofer into the drywall the same way, then tighten the screws. This will cause the nylon bracket to “pinch” the drywall and will hold the speaker firmly in place. If using a drill/driver, set the clutch to a low setting to prevent overtightening and possible damage to the frame. If using hand tools, tighten just until firm. A cutout template is supplied with the subwoofer for your convenience in cutting the drywall.

WIRING

When wiring from a mono amplifier, connect both the positive and negative leads to the same set of terminals, then run a set of speaker wire to the opposite set of terminals, observing polarity. This will connect the woofers in parallel for a total of a 4 Ohm load. This is shown in the picture below. A series connection may also be used, creating a 16 Ohm load.

When wiring from a stereo amplifier, connect one set of leads to each set of terminals, observing proper polarity. This will connect each woofer individually as an 8 Ohm load. This is shown in the picture below.
