Description
The Bosch LC20-PC60G6-8E speaker system is a complete high performance two-way ceiling speaker package. The Bosch LC20-PC60G6-8E is ideal for background and foreground music, voice evacuation, paging, and sound reinforcement applications. The Premium Ceiling Speaker provides a unique combination of high acoustic output, superb coverage control, high power handling and wide dispersion, to cover virtually any size listening area.
The LC20-PC60G6-8 comes completely assembled with an integrated bezel assembly, grille, rear enclosure, 8-inch (200mm) coaxial two-way speaker and internal high power line-matching transformer. The speaker features a waveguide coupled true compression HF driver and a long excursion 8-inch (200mm) woofer. The LC20-PC60G6-8 speaker utilizes a 2nd order crossover network at 2.5 kHz, with a comprehensive protection circuit to protect the network, woofer, and tweeter drivers from excessive power levels. The LC20-PC60G6-8 utilizes a transformer that offers a selection of 7.5W (70-V only), 15, 30 or 60 watts delivered to the speaker system using either 70-V or 100-V lines, or 8 ohm bypass.
Selection is via a convenient switch on the front baffle. The perforated grille is fully zinc plated and finished in semi-gloss white powder-coated enamel. The baffle and bezel are constructed from fire rated ABS. The rear enclosure is constructed from zinc-plated, heavy gauge steel. The rear enclosure, with fiberglass damping material, provides an optimum internal volume for extended low-frequency performance. A rear cover, with provisions for a junction box fitting, provides access to a 4-pin terminal block that allows direct connection to the speaker with up to 12 gauge wire and provides pass through to additional speakers. For special voice evacuation installations a ceramic terminal block is provided and attaches to the speaker back can enclosure under the rear connector cover. Two adjustable metal tile bridges and metal “C” ring are included for safe suspension of the LC20-PC60G6-8 ceiling systems in a drop ceiling that uses mineral wool, or other fiber-based ceiling tiles
