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 vents with radiused 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.
