Custom Subwoofer Box Grille Blueprint - Perforated Speaker Panel Drawing

This document is a blueprint-style line drawing, uploaded as 'box with grill.jpg' as part of a custom car-audio build set for a 1994 Ford Bronco. It depicts a rectangular panel, apparently the front grille of a subwoofer/speaker enclosure, covered edge-to-edge with a dense hexagonal pattern of small circular perforation holes arranged in offset rows. Behind the perforation pattern, faint circles suggest the positions of what appear to be four large round speaker/driver cutouts (two larger in the center-right area and additional circles toward the sides), indicating where drivers would sit behind the grille. A thin rectangular border frames the drawing. The document contains no visible text: no dimensions, tolerances, material callouts, part numbers, or title block information are legible. As one page of a multi-page set that includes sub box cut sheets, top and side views, and grille support frame drawings, this sheet serves as the visual reference for the perforated grille face of the speaker enclosure. Readers can learn the general hole layout/pattern of the grille and the approximate placement of speaker openings, but no measurements or specifications can be extracted from this page alone.
