RCF COMPACT M 10 Passive Speaker.A versatile two-way full-range speaker system, COMPACT M 10 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 huge magnets and wave-guided compression drivers, the M 10 has great sensitivity, which is typical of professional audio cabinets. It also has HI-FI sound quality with a smooth and wide frequency response. The M 10 can deliver low-distortion audio at an SPL level that much exceeds expectations for such a small solution. Even in environments with architectural restrictions, the M 10's sleek and compact design and precise craftsmanship make it acceptable. M 10 can be installed on walls or ceilings with the help of optional mounting attachments.
