Professionals Go For Gold
It has often been said that Eminence professional loudspeakers are not expensive enough. A genuine American-built cast-frame high performance transducer must surely cost considerably more -- after all, most other premium speakers do.
The fact is that nobody else in the world makes quantities like Eminence and nobody else can waste as little during the manufacturing process. If they made fewer and rejected more, they could match their prices. Eminence Pro models have always been a remarkably good value. Following a series of detail revisions, they are now an even better value.
The major cause of failure in a loudspeaker is thermal overload. Expansion of moving parts -- even melting of parts -- is terminal. Some time ago, Eminence approached DuPont about formulating a special type of Kapton that could efficiently deal with extreme heat conditions. Except for rare accidental overloads, this material all but eliminated voice coil failures.
Eminence has further developed manufacturing techniques with this material and investigated other problem areas in transducer motor structures. The combined effect of a number of seemingly small adjustments to production techniques, component materials and adhesives has yielded dramatic improvements in power handling.
The transducers in the revised Pro range offer power handling improvements of up to 50%. The popular Omega Pro series, originally rated at 600W, is now rated at between 700W and 800W. The Kappa Pro 15LF, once rated at 400W, is now rated at 600W. To recognize these models, look for their gold back plate labels.
Now more than ever, selection from this range demands a more considered approach than simply reviewing power handling and sensitivity. It is recommended to consider the sensitivity chart and a review of the Thiele-Small explanations as a prelude to selecting samples for computer modeling of enclosure designs and listening tests.
The Eminence professional series represents a collection of the most widely used professional loudspeakers in the music industry. From indoor or outdoor concerts, to churches, night clubs, recording studios and arenas all over the world, Eminence has become well known for virtually all applications. Eminence earned this reputation from engineering and manufacturing transducers that incorporate incredible innovations in an affordable package. Why pay more for an over-engineered product?
