The ModularDesign™ Series offers exceptional performance in a wide variety of applications, including houses of worship, performing arts facilities, hotels, casinos, night clubs, and sporting facilities. Specifying MD Series is appropriate anywhere there is a need for dependable high performance loudspeakers with predictable coverage and extended frequency response. For design / build contractors and electroacoustic design consultants, the MD Series offers an effective solution to the myriad of challenges encountered in the design and implementation of permanently installed sound reinforcement systems.
Designed as a family of modular, arrayable loudspeakers, the full-range MD family includes six models: three models with 12" LF sections, and three with 15" LF sections. Nominal coverage patterns of 60° x 40°, 90° x 40° and 120° x 40° are available with either low-frequency complement. In addition, two low-frequency only MD systems, the MD-L115 and MD-L118, share the common form factor of the full-range systems. All share the same 35" tall, 30° trapezoidal enclosure as their MD Powered Series counterparts.
The form factor common to all MD loudspeaker models makes creating full range or combined full range/low-frequency clusters painless. The enclosures are designed with 30° angles; wall-to-wall tight packing enclosures splay the 60° x 40° horns perfectly and provide uniform coverage in any multiple of 60° to 360°. No gaps or spacers are required and the radial form of the front surface of the enclosures forms a contiguous cylindrical surface for a clean and aesthetically pleasing appearance. Each enclosure is equipped with a total of fifteen 3/8"-16 threaded attachment points offering the installer tremendous flexibility in suspension and mounting.
Low-frequency transducers feature technically advanced 4" voice coils assembled with proprietary high temperature adhesives, vented magnet assemblies and highly optimized motor design to provide excellent dynamic range, flat frequency response and a very low distortion figure.
High-frequency compression drivers feature a Neodymium magnet motor structure and 65 mm (2.5") aluminium voice coil and titanium diaphragm plus a pole piece mounted copper shorting cap for extended HF response.
Clusters of MD speakers can provide up to 360 degrees of coverage.
