According to AtlasIED, the SFMS also decreases installation time by up to 60 percent. Its mounting design is simple install steps without the need for any tools. A front mounted 70V tap selector allows installers to quickly adjust and set the 70V power taps. A removable four-pole euro-style connector allows for easy pre-wiring and daisy chaining of additional loudspeakers and subwoofers. The result is fewer labor costs and better profits. The improved waveguide design provides wider coverage than previous models. The benefit is cost savings due to fewer loudspeakers required, while still maintaining uniform sound throughout. Low-frequency response is enhanced and deeper bass definition is provided via the optimized low frequency tuning port. Additionally all models are safety listed to both UL1480 and UL2043.
