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") aluminum voice coil and titanium
diaphragm plus a pole piece mounted copper
shorting cap for extended HF response.
Features
• All full range models feature a rotatable high-frequency
horn, enabling them to be utilized in a vertical or
horizontal configuration
• Available in either black or white finishes
• All full range and low-frequency enclosures employ the same
overall dimensions and identical attachment point locations
• All models constructed in a trapezoidal design of multi-ply
birch with a powder coated steel grille
