Delta Pro 15 Cast Frame Speaker:
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. 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.MADE IN THE USA:
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 the latest innovations in an affordable package. Why pay more for an over engineered product? Do what the professionals do: put Eminence Inside!

Comments about Eminence Delta Pro 15 Cast Frame Speaker:
First off, I used this with a couple of horns to make a full range cabinet to play a bass through, About a 5.5 cu foot box, ported at about 42 hz. The very first thing you will notice is the efficiency of the driver, the 100+db@ 1 watt is not at all over rated. It will produce hugh sounds almost effortlessly. There is very little color to the sound, natural and open with a but of a peak (guessing) at maybe 1000hz, this serves to make for very clear vocals. Now for playing a bass through, or guitar, a natural sounding speaker is the last thing people want. Color is the order of the day. I use a DSP effects / amp modeler. So for this it is GREAT. You don't want to simulate one cabinet through another cabinet, so this driver lets the DSP do it's thing without adding additional 'clutter' to the sound. If you were just replacing a bass cabinet driver, you might want to consider another unit specifically an insturment driver that will add the charicter you want, but for a full range, sounds clear and natural, you can not beat this driver, and if you are already using an amp simulator, this will be perfect.
