- SB13PFC25-8 Cutout & Recess Template (NB Audio) Straight off SB Acoustics' spec sheet: flange outline, bolt holes. Scaled from SB Acoustics' drawing, so close but not guaranteed exact: cutout. Left out: recess depth not on file, so measure your flange. Check it against your driver before you cut.
