American International NSB710 Speaker Mounting Brackets

Features

6-3/4 Speakers: For a 6-3/4 speaker to fit in the opening of this bracket, the tabs around the inner speaker opening will need to be removed. They are scored along the bottom for easy removal, but still may require pliers and a file.

6-1/2 Speakers: 6-1/2 speakers with the 3-hole or 4-hole bolt pattern can be mounted using the tabs around the inner speaker opening of this bracket (if the hole spacing matches).

5-1/4 Speakers: While a 5-1/4 speaker will mount easily in this bracket given the bolt pattern, the frame of a typical 5-1/4 is approximately 1/2" smaller than the opening in the bracket, making a 6-1/2 or 6-3/4 a better fit. When using a 5-1/4, a speaker baffle must also be used to seal the rear of the speaker.
