Models RE84, MR8, TB8
The RE84 Ceiling Speaker Enclosure is a protective
enclosure for an 8" speaker, designed for recessed
installations, and for use with any of the Bogen ceiling
grilles. One-piece steel construction includes a
mounting ring and a foam insert to reduce metallic
resonance. The RE84 is finished in rust-resistant
primer and is tapered for easy stacking. UL approved. 
The MR8  Mounting Ring is a cold-rolled steel unit
which will mount any of the Bogen ceiling grilles, for
installations where the RE84 is not used.
The TB8 Tile Bridge is a load-bearing T-bar support
designed to sustain the weight of an 8" speaker, grille
and protective enclosure in suspended ceiling con-
struction. Use of the TB8 improves environmental
safety and eliminates unsightly sag in 2'-by-2' and 
2'-by-4' acoustic ceiling tiles.
