| What's ribbon transducer? The ribbon transducer
is quite old as a concept, and was developed by European Acoustic
Laboratories in 1928.
Fundamental physics support the ribbon as the most perfect type
of transducer. A thin light metal ribbon is suspended in a powerful
transverse magnetic field. The signal current passes through the
current and magnetic field. The electromagnetic circuit has complete
control over ribbon motion. The ribbon itself projects the sound.
The ribbon serves both as voice coil and diaphragm. Every part of
the ribbon is driven directly and simultaneously without any energy
storage.
The ribbon transducer improves the performance of loudspeaker systems
for the following reasons:
| 1. |
No sound coloring, in usable frequency range output voice
always fidelity to input signal. |
| 2. |
Speed of response, start and stop in instantaneous, permit
it to maintain the leading edge of musical sounds and their
harmonics. |
| 3. |
Extremely low inter-modulation and harmonic distortion |
| 4. |
Extremely low mass device. |
| 5. |
Capable of the highest efficiency known in direct radiator
transducers. |
| 6. |
High rate of Young's modulus. |
| 7. |
Extremely wide, flat frequency response (800Hz through 100
KHz.) |
| 8. |
Flat impedance in usable frequency range that easy to design
X-over. |
Summary
The ribbon loudspeakers are superior to other transducers because
all design factors are correct. Other high range extenders do not
blend easily when added to loudspeaker systems because they add
their own distortion by transient smearing, energy and non-linear
response. The quality of materials used in ribbon speakers has the
ability to "clean up" and "open up" not only
the extreme highs, but also the middle tones without adding any
distortion. The addition of a pair of ribbon loudspeakers to any
quality speaker system is the most cost effective way to improve
the performance of a loudspeaker system.
