The model MS125S is an ultra compact low frequency loudspeaker system. The dual 15" JBL low frequency transducers combined with an acoustically optimized enclosure design provide powerful transient bass with minimum power compression and distortion. The internal low pass passive network replaces the need for an external electronic crossover when using with other Marquis Series systems in a complete installation.

The compact rectangular enclosure enables this system to be located in discrete locations or stacked together for maximum acoustic coupling.

The rugged plywood construction of the enclosure, along with a textured DuraFlex finish and a heavy duty zinc treated steel, foam-backed grille and treated cones enable this Marquis Series enclosure to meet with environmental test specifications.

Designed for permanent installation, the MS125S is part of the Marquis Series, a complete range of installation loudspeaker systems.

JBL continually engages in research related to product improvement. New materials, production methods, and design refinements are introduced into existing products without notice as a routine expression of that philosophy. For this reason, any current JBL product may differ in some respect from its published description, but will always equal or exceed the original design specifications unless otherwise stated.
