The MD (ModularDesign) Series Powered Loudspeakers

combine the superb loudspeaker performance of MD

with the latest generation of QSC’s legendary amplification

and signal processing technologies. For more detail about

the PM modules, see the rear page.

MD Powered 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 Powered is appropriate

anywhere there is a need for dependable high

performance loudspeakers with predictable coverage,

extended frequency response and the precision of

integrated power amplification and signal processing.

For design/build contractors and electroacoustic design

consultants, the MD Powered Series offers an effective

solution to the myriad of challenges encountered in the

design and implementation of permanently installed

sound reinforcement systems.

The MD-LP115 and MD-LP118, share the common

form factor of the full-range systems in the MD Powered

Series. All share the same 35" tall, 30° trapezoidal

enclosure as their passive MD Series counterparts.

The form factor common to all MD loudspeaker models

makes creating full range or combined full range/low-

frequency clusters painless. 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.
