The MULTY12F is a high-performance, two-way, multi-purpose loudspeaker featuring one 12-inch woofer and one 1-inch high-frequency driver. The woofer incorporates both MMSS (Mirror Mechanical Suspension System) and MALTCROSS technologies. MMSS technology ensures symmetrical positive and negative excursion of the moving assembly, thereby achieving significantly lower harmonic distortion. MALTCROSS represents our latest innovation in thermal management; our clear objective regarding heat dissipation is to ensure that the driver delivers consistent, reliable, and optimal performance within the system—maximizing overall Sound Pressure Level (SPL) while guaranteeing stability. The high-frequency driver utilizes PM4 diaphragm technology, which employs advanced polymer materials—previously unprecedented in the audio industry—to establish a stronger bond between the dome and the voice coil former. This design enhances the driver's performance during prolonged, high-power operation, resulting in a more natural and authentic sound reproduction.
