Description
4" High-Compliance Speaker with TLM-870 Transformer
High compliance 4 inch single cone driver with mounted 70V transformer provides wide frequency response and wide dispersion for paging and background music.
Lowell Model JR410 is a commercial industry standard 4" (EIA 5") speaker. that features a 10 oz. magnet for high power handling and sensitivity. It includes a 1" copper voice coil, plated steel basket, and high compliance treated cloth surround and is specifically engineered to provide wide frequency response and wide dispersion for solid performance in paging and background music systems. It's specified for reliable performance in commercial, industrial, and institutional applications including offices, public buildings, airport corridors, educational and medical facilities. The driver's small size and broad beamwidth of 170-degrees make it especially useful in rooms with low ceilings. The loudspeaker frame is stamped 20-gauge steel with a zinc-plated finish to prevent corrosion. For versatile application, the speaker is available with a selection of factory-wired transformers and will fit all standard 4" ceiling grilles and backboxes.
