Owner's manual for the OEM IO-510 2-way indoor/outdoor cabinet loudspeaker, covering box contents, features, installation with U-bracket or optional double-swivel bracket, and specifications.
The IO-510 is a 2-way indoor/outdoor cabinet loudspeaker featuring a sealed, port-less design that resists moisture and insects. It ships with mounting hardware and is available in white (IO-510W) and black (IO-510B) finishes.
Follow the manufacturer's instructions for the bracket itself. To prepare the speaker: remove the endcaps by pulling the back end away from the enclosure, then loosen and remove the brass thumb screws holding the original bracket. Remove that bracket and replace the thumbscrews, tightening them securely with your fingers. Slip the front edge of the endcaps into the available grooves and press them back into place, ensuring they engage the thumbscrews. The double-swivel bracket attaches to the back of the speaker using 1/4-20 screws or bolts (typically about 1/2" to 5/8" long, depending on bracket thickness). You will need to remove the terminal cover from the back of the speaker as described above.
