Designed for Russound’s 6.5” IC-Speakers and can be used with any brand’s 6.5” loudspeakers that have an 8.25” cutout size. This is the most common size for 6.5” speakers in general in the industry. The internal opening of the SB-C67 bracket is 8.375” with 1/8” extra so that a 6.5” speaker fits in easily.
