The LS9900 is our flagship full-range tri-amped true line source array module. Its primary application is large venues that require the ultimate in high fidelity.

Two versions of the LS9900 are offered, LS9900 for permanent installation and LS9900T for touring applications. The touring version comes standard with a wheel tray and more advanced rigging for easier use in the criteria specific to its application.

The LS9900(T) high frequency section features two high performance PRD1000 planar ribbon transducers designed and manufactured by SLS Loudspeakers. The unique design and properties of the planar ribbon driver allows precise acoustical coupling of the array and hence, full utilization of line source (cylindrical waves) benefits.
The midrange section uses four 6 ½” drivers that are very similar to the midrange drivers used in the highly acclaimed S1065 and S1266 critical high output studio monitors. The low frequency section uses two high-powered 15” drivers carefully matched for coverage consistency and lower SPL deviations.
