Metal Backbox, Cloud 12

C12BB3

Note: Picture shows backbox with grille.  Grill sold separately.

The Community C12BB3 professional steel ceiling loudspeaker backbox has been engineered to provide optimal performance with Community’s CLOUD Series 12-inch coaxial loudspeakers and 12- inch subwoofers. To provide unmatched low frequency performance, 21 L-shaped steel ribs are welded internally to rigidly brace the enclosure. A system of acoustical damping including a heavy mastic coating sprayed onto the interior steel surfaces and fibrous poly padding are provided to quiet undesirable metallic resonances like those found in other backboxes. 

Features:

• Best-in-class construction and acoustical
  performance.
• Welded steel enclosure (1.2 mm).
• Industry standard form factor.
• 21 welded, unitized steel rib structures for
  maximum enclosure rigidity.
• Two different-sized conduit knockouts are provided
  on each of four sides of the enclosure
  [1/2" (13mm) and 3/4" (19mm) nominal].
• Welded ¼-20 nuts on the rear panel accommodate
  Community’s optional 1/4EYBLTKIT accessory (kit
  of four forged eyebolts, 1" (25mm) ID, black) for
  suspended installation.
• Four slotted tabs accommodate mounting
  Community’s optional channel rail accessories for
  recessed ceiling enclosure support. 23.75", 30"
  and 47.75" channel rails (part nos. RAIL24-PR,
  RAIL30-PR and RAIL48-PR respectively), sold in
  pairs, are available.
• Enclosures are treated with a heavy acoustic
  mastic coating to minimize steel resonance.
• Each enclosure is padded with 1" (25mm) premium
  poly acoustic lining to minimize internal reflections.
• Low gloss black paint finish.
• Designed for use with Community’s CLOUD1266, CLOUD1299 and CLOUD12SUB 12-inch ceiling systems.
