RCF MB10N251 10" 300W 8 ohm Neodymium Mid-Bass Speaker Driver

The RCF MB10N251 is a lightweight, high-efficiency 10" neodymium mid-bass speaker designed for professional sound systems where linearity, precision, and durability are key. Delivering 600W program power with 97 dB sensitivity, it features a 2.5" aluminum voice coil on a fiberglass former for excellent thermal and mechanical performance. With a wide frequency range of 50 Hz to 3.5 kHz, the MB10N251 is ideal for compact, full-range enclosures or mid-bass applications. Forced air ventilation, an M-roll polycotton surround, and exponential cone geometry ensure precise low-frequency reproduction and extended reliability under heavy use.
