Frequently Asked Questions regarding the JMC Soundboard

What is different about it in comparison with traditional loudspeakers?
Loudspeakers generate a focal wave and it takes two of them for the listener to be at the intersection of two waves. The Soundboard generates an omnidirectional wave. Listeners can be near, far or even in another open space, and they can perceive the music on the same level of quality. The Soundboard is crafted in the tradition of musical instruments that actually play music for us. The impression is that of a concert, with a powerful presence, precision and a well-rounded sound. Music is heard and sensed in all its dimensions.

How does the stereo effect work?
The two signals from the two channels are physically mingled in the membrane. In terms of the rendering, when it comes to the presence of the music generated by the Soundboard, one could really speak of a three-dimensional rather than a stereo sound. The listener is literally enfolded in or immersed within the musical climate. While there is less panoramisation than in a conventional system, the Soundboard creates more sound levels and more depth of field. 

Is there enough bass?
Yes, like a musical instrument such as the piano, the naturally generated bass tones are clearly present. Just like a guitar with a resonance spruce soundboard that has to be regularly played for three years to develop its full potential, the Soundboard will further enrich its frequencies according to the number of hours of listening and vibrations. The position of the Soundboard can also enhance its ability to emit bass tones, such as installing it in an angle.


Where is the resonance chamber?
One can in fact see the all piece as a resonance chamber, and the Soundboard plays the role of a vibrating membrane. Despite what one reads on the topic of resonance chambers which are said to amplify sounds, they in fact mostly serve to enable listeners to hear all the frequencies emitted by the soundboard by reducing the acoustic short-circuit inherent to the moment when a membrane begins to vibrate. Moreover, the materials from which they are made have a strong influence on its timbre, which is a bad thing as far as the Soundboard is concerned, which is why it has been reduced to a totally muffled cover.

Are all Soundboards identical?
They are made in the same way, but they are nonetheless all a little different in that they are built from a living material, spruce. Like all musical instruments, they will evolve in their own particular way, depending on where they are installed, the music they play and the people for whom they play.

What equipment should be associated with a Soundboard ?
The Soundboard needs enough energy to reveal its full potential. The amp should deliver a minimum power of 2 x 80 watts under 8 Ohms. Obviously, the higher the quality of the input signal, the more the Soundboard will be appreciated. This instrument reveals all the details of your sources, which means you must be attentive to their quality (CD, player, Ipod, MP3 compression).

What is the best position for my Soundboard ?
The Soundboard is generally fixed flat against a wall, with its axis positioned about 1.5 metres from the ground. It should where possible not be placed too high, since one loses the sense of proximity and even companionship with this instrument. If placed in an angle, it will generate more bass tones, and less if it is placed on a stand well away from a wall.

How do I install my Soundboard ?
The Soundboard is very simple to install. Four screws and plugs (to be adapted according to the material) driven into the wall are enough to support its mounting. Connecting it is done in a conventional manner, by connecting the left and right channels of the amp terminals on the back of the Soundboard, exactly like on traditional loudspeakers.

How must I take care of my Soundboard?
It should ideally be kept in surroundings with a constant humidity rate of around 35%. It will evolve according to the type of music you listen to and the number of hours spent doing so. The wood as specially selected, gathered according to the season and the moon; it was then left to dry and stabilise for around five to eight years. Finally, we have created within the workshop a storage area with ultra-dry 12% hygrometry conditions. The Soundboard will thus not be liable to crack provided it is not exposed to full sunshine, nor placed above a radiator or a fireplace. A damp cloth is enough to clean it. You must not under any circumstances use a product containing silicon, an ingredient found in many wood-care products.


What guarantee does it come with?
JMC Lutherie offers a two-year guarantee on Soundboards, as well as a five-year effective guarantee on the membrane, provided the Soundboard has been properly maintained.
