The MULTY15F is a high-performance, two-way, multi-purpose loudspeaker featuring one 15-inch weather-resistant woofer and one 1.4-inch compression driver. The woofer incorporates MMSS technology (Mirror Mechanical Suspension System), which ensures symmetrical positive and negative excursion of the moving assembly, thereby achieving significantly lower harmonic distortion. MALTCROSS represents our latest thermal management technology; in addressing heat dissipation challenges, our clear objective is to ensure that the driver unit delivers consistent, reliable, and optimal performance within the system—maximizing overall Sound Pressure Level (SPL) while guaranteeing stability. The compression driver utilizes a titanium diaphragm, capable of delivering exceptional SPL across an extremely wide frequency range to produce sound that is both clear and transparent.
