The RCF MB10N251 is a lightweight yet powerful 10-inch neodymium mid-bass driver designed for high efficiency, excellent linearity, and superior power handling. Featuring a 2.5-inch aluminum voice coil on a fiberglass former, it ensures precise low-frequency reproduction with minimal power compression. The M-roll surround and exponential cone geometry provide smooth response and controlled displacement, while the forced air ventilation system enhances heat dissipation for consistent performance.
