The Adamson M15, multi-purpose cabinet, features an extremely low profile, symmetrical trapezoid design, with a 50-degree conical waveguide. This unique combination allows any two cabinets to work together in a mirror image monitor configuration. The cabinet is loaded with a single Adamson ND-15 Kevlar/Neodymium Driver, marking the launch of Adamson’s Advanced Cone Architecture – This breakthrough technology makes the ND15 the only 15” driver with zero axial modes in its entire passband, dramatically increasing the linearized mid-range response, while maintaining a rock solid bottom end (impossible to achieve with a 15-inch paper driver). The top end is covered by a 4-inch high frequency compression driver, giving it extremely high SPL throughout the bandwidth. The lightweight package (56.5lbs/25.63 g) is equipped with a switchable internal crossover, allowing bi-amped or passive operation.
