QSC ModularDesign Subwoofer MD-S215 Specification Sheet

Features
• Flat response down to 24 Hz
• Sixteen 3/8"-16 threaded attachment points address all
suspension requirements
MD Subwoofers offer exceptional performance in
a wide variety of applications, including houses of
worship, performing arts facilities, hotels, casinos,
night clubs, and sporting facilities. For design/build
contractors and electroacoustic design consultants,
MD Subwoofers offer an effective solution to the
myriad of challenges encountered in the design
and implementation of permanently installed sound
reinforcement systems.
The MD-S215 and MD-S218 subwoofers offer dual
15" or 18" front-loaded transducers, respectively.
Large centrally located
terminations eliminate port turbulence and noise.
Transducers feature technically advanced 4" voice
coils assembled with proprietary high temperature
adhesives, vented ceramic magnet assemblies and
highly optimized motor design to provide high linear
excursion, low power compression, flat frequency
response and a very low distortion figure.
