Q1.What does Murata do?
Murata is an electronics ceramics component manufacturer. Please go to http://www.murata.com/ to know more about Murata.
You can find components for variety of consumer electronics products.
Several years ago, one of the laboratory of R&D department developed a spherical ceramic ball with a grapefruit size letting it work as a omni-directional (or one point source) loudspeaker. This was origin of the Murata "Harmonic Enhancer."
Q2. What are the characteristics?
Please go to Overview and Specs ES105A.
Q3. Sound of 15kHz and higher? Can I hear? What is the advantage?
This question has been most frequently asked since we put this into market. However, most of them were convinced after they added ES105A to their speaker systems. 15kHz is hard to hear for most human kind. However, you can recognize the difference of the sound when you hear music with combination with other speaker systems. You feel the improvement in your bass and middle sound as well as the high tones. The soundstage certainly become clearer, larger, deeper, and closer.
Q4.Why is the transient faster than other tweeters?
Different from conventional dynamic type tweeters, ceramic spherical tweeter is designed to have self-resonant frequency at the higher side of its working frequency range. As known well, the vibration system that has higher resonant frequency shows faster transition characteristics compared with the one having lower resonant frequency. Thus, ES105A is able to achieve excellent transient response.
Q5.Why does this have wide dispersion?
This is what the breathing vibration of the spherical piezo ceramic does. The spherical figure vibrates just like a lung swell and shrink, breath. Thus, the sound energy is dispersed into wide angle in breathing vibration mode.
Q6.What is the transient? How fast is the transient?
Transient is a characteristic, which designates the time delay of output to the input. Actuality is the diaphragm movement to the input signal. Refer Q4 for more.
Q7.How should I place the tweeters?
If your speaker system has a flat surface on top, just place where you like the total sound best. If the top surface is not flat, place near by the speaker using appropriate speaker stand.
Q8.Does the sound get better for all kind of source?
Yes. They work well for all; CD, vinyl, SACD or even DVD audio. Naturally, the better-recorded album gives better sound. In any case, you will see the improvement by the Murata "Harmonic Enhancer.".
