Description

The three FRB models covered in the manual were designed to accommodate a variety of Boston Acoustics round in-ceiling loudspeakers. They meet the stringent requirements of electrical codes throughout the country for fire and plenum rated enclosures. Such enclosures are often required by building codes in commercial

applications and in town homes or condominiums.

Each FRB model is made from heavy gauge steel that is both heat and fire resistant. A 2” layer of insulation lines the inside of the enclosure and provides up to 10dB of acoustical isolation between adjoining rooms. Each unit also includes internal mounting posts for 70/100 volt transformers for use in commercial applications or home audio systems where many speakers are used or where speaker wires must be run over long distances.
