Description
TOA F-1522SC Full-Range Ceiling Speaker 4" 25/70.7 V Transformer 6 W 8Ω
Product Details
The F-1522SC ceiling and wall-mounted speaker covers an extremely wide area and can be used for 25, 70 and 100 V line applications. Well-balanced sound can be heard uniformly at any location.
Drive components are 10 cm cone-type. Rated input is 6 W (High Impedance). Sensitivity is 88 dB (1 W, 1 m). Frequency response is 65 Hz - 18 kHz (-10 dB), 45 Hz - 20 kHz (-20 dB).
A multi-tap transformer lets it sit on a 70 V or 100 V distributed line, which is how a building-wide system runs many speakers from one amplifier; a low-impedance tap is there for a conventional installation. Supplied with panel x 1, paper pattern x 1. Weight is 1 kg.
Features
