The IC-400-T is a 2-way speaker system housed in a durable ABS plastic enclosure with a paintable white grille. It uses a 5-inch polypropylene woofer for mid-bass frequencies and a 1-inch aluminum dome tweeter mounted in a controlled-dispersion pattern to provide a wide, even coverage area. The speaker is easy to install using a secure dog-leg mounting system. Its primary feature is the built-in multi-tap transformer, which allows installers to select different wattage taps (e.g., 2W, 4W, 8W, 16W for 70V systems) to effectively balance the sound levels across multiple speakers on a single speaker line, reducing wiring complexity and amplifier cost in commercial installations.
