A mid-range issue on a Beovox S120 can sometimes come from dust or debris affecting the speaker area rather than a failed driver. Before opening the cabinet, it’s worth checking the grille, driver surface, connections, and amplifier output carefully. For small speaker openings, a gentle phone speaker cleaner can also be useful for removing loose dust without applying pressure to the driver. If the mid-range remains weak or distorted after cleaning, testing the driver and crossover components is the better next step rather than forcing higher volume.
