The 3017 BG17 full-range speaker from Visaton is designed with a relatively flat frequency response and high output, using a paper cone with whizzer cone and treated paper accordion surround. Typical applications for the BG17 include: small stage monitor, 70V and 100V distributed audio systems (with provisions for transformer mounting built-in), full-range open baffle speakers, or as an instrument speaker for guitars, keyboards, and organs.
