RCF COMPACT M 04 Passive Speaker.A versatile two-way full-range coaxial speaker system, COMPACT M 04 is appropriate for a variety of applications. For the finest intelligibility in close-range applications, its balanced sound is a huge value. Due to the use of larger magnets, M 04 has a high sensitivity as well as an HI-FI sound quality with a smooth and wide frequency response. The M 04's SPL level of low-distortion audio considerably exceeds expectations for such a small solution. Even in environments with architectural restrictions, M 04 can be used because of its attractive and compact design and precise finishing. The M 04 may be installed on a wall or a ceiling thanks to the included wall mount bracket.
